Strategic Report
for the Year Ended 31 December 2024


The directors present their strategic report for the year ended 31 December 2024.

Business Model

REVIEW OF BUSINESS
The results for the year and financial position of the company are shown in the annexed financial statements.

The company is a member PDS group of companies, Netherlands, has been delivering innovative software technologies, R&D and consulting services to the Exploration and Production Industry for nearly thirty years.

The profit for the year after taxation amounted to £277,110 Loss (2023: £151,159 Loss).
The company retains a positive combined bank balance of £850,876 (2023: £1,267,878).

The directors are satisfied with the results in the year under review in a progressively competitive industry with tough trading conditions.

PRINCIPAL RISKS AND UNCERTAINTIES
The company's principal financial instruments comprise cash, short term deposits and various items such as trade debtors and trade creditors that arise directly from its operations. The main purpose of these financial instruments is to fund the company's operation as well as to manage working capital, liquidity and invest surplus funds.

The directors continue to assess the risks facing the company, Both the securing of new business and maintaining existing relationship are key to the company's success.

From the perspective of the company, the principal risks and uncertainty are integrated with those of Petrotechnical Data System International Group and are not managed separately. Petrotechnical Data System International Group has single risk-based control framework to identify and manage risks. The Group’s framework applies to all wholly owned group member companies and accordingly the principal risk and uncertainties are discussed in Petrotechnical Data System International Holding B.V, the ultimate parent company. The group report does not form part of this report.

Other ongoing challenges are overhead cost control which is kept under regular review by the director.

MARKET
The company monitors the general economic and political changes in the information technology sector. The directors pay attention to these changes and tailor their services and agreement in order to maintain the level of income and profitability.

COMPETITIVE
The main competitive risks to the company arise from major systems integrators blocking niche suppliers. The company continues to invest in providing competitive technology and working in partnership with research establishments to develop innovative products with unique value propositions and competitive edge.

LEGISLATIVE RISK
On a regular basis the directors review the company legislative risk exposure and ensure that all applicable directions are observed

Strategic Report
for the Year Ended 31 December 2024

FINANCIAL INSTRUMENT RISK
The company has established a risk and financial management framework whose primary objectives are to protect the company from events that hinder the achievements of its performance objectives.The objectives aim to limit undue counterparty exposure, ensure efficient working capital exists and monitor the management of risk at a business unit level.

SECTION 172(1) STATEMENT
This statement sets out how i.e. Directors have approached and met their responsibilities under section 172 Companies Act 2006, acting in a way that they consider would most likely promote the long-term success of the Company for the benefit of members.

OUR CLIENTS
Delivering high quality software and excellence in customer service is critical to the success of the business. We conduct regular customer satisfaction surveys as part of our regular feedback process. This feedback is taken both in survey format and through formal meetings with customer representatives as well as in writing, in person and over the telephone. The Directors receive regular updates from the customer feedback to implement service improvements were applicable. This can range from improvements in the customer on-boarding process itself to changes in services we offer to our customers while they are progressing in their software implementations.

OUR SUPPLIERS
The company is a subsidiary of PDS group of companies, though which the company develops its main products. The Directors receive regular operational updates as part of Board meetings and any significant development in a key supplier relationship, such as strategic changes in the sector is escalated to the Board immediately. Supplier contracts are reviewed on an annual basis by Directors.

KEY PERFORMANCE INDICATORS
The directors have considered the use of the key performance indicators. However due to the relatively small size and niche market for the company's services, KPI's will not be pertinent for any decision making. The directors have considered that it would be better to use the parent company audited accounts to establish the relevant indicators

Accordingly, these factors represent a material uncertainty that may cast significant doubt on the company's ability to continue as a going concern. The directors have taken steps deemed necessary as disclosed in the Note 3, the accounting policies and notes to the accounts.

Report of the Directors
for the Year Ended 31 December 2024

ENVIRONMENTAL STATEMENT
The company is deeply committed to worldwide conservation. We believe that the preservation of our natural and cultural heritage is best accomplished through the sustained unification of environmental and economic goals.

Our goal is to provide long-term support for existing natural ecosystems to ensure that human populations, flora and fauna continue to survive and coexist successfully. Our vision includes working together with local people and regional non-government organisations to inspire and develop sound community health and conservation practices and assist in mitigating global climate change.

STATEMENT OF DIRECTORS' RESPONSIBILITIES
The directors are responsible for preparing the Strategic Report, the Report of the Directors and the financial statements in accordance with applicable law and regulations.

Company law requires the directors to prepare financial statements for each financial year. Under that law the directors have elected to prepare the financial statements in accordance with United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law), including Financial Reporting Standard 102 'The Financial Reporting Standard applicable in the UK and Republic of Ireland'. Under company law the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the company and of the profit or loss of the company for that period. In preparing these financial statements, the directors are required to:

-select suitable accounting policies and then apply them consistently;
-make judgements and accounting estimates that are reasonable and prudent;
-state whether applicable accounting standards have been followed, subject to any material departures disclosed and
explained in the financial statements;
-prepare the financial statements on the going concern basis unless it is inappropriate to presume that the company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the company's transactions and disclose with reasonable accuracy at any time the financial position of the company and enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

STATEMENT AS TO DISCLOSURE OF INFORMATION TO AUDITORS
So far as the directors are aware, there is no relevant audit information (as defined by Section 418 of the Companies Act 2006) of which the company's auditors are unaware, and each director has taken all the steps that he or she ought to have taken as a director in order to make himself or herself aware of any relevant audit information and to establish that the company's auditors are aware of that information.

AUDITORS
The auditors BBK Partnership are deemed to be reappointed under section 487 (2) and of the Companies Act 2006

ON BEHALF OF THE BOARD:





Ms V S O'Connor - Director


23 September 2025

Report of the Independent Auditors to the Members of
Petrotechnical Data Systems Limited


Opinion
We have audited the financial statements of Petrotechnical Data Systems Limited (the 'company') for the year ended 31 December 2024 which comprise the Income Statement, Other Comprehensive Income, Statement of Financial Position, Statement of Changes in Equity, Statement of Cash Flows and Notes to the Statement of Cash Flows, Notes to the Financial Statements, including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 'The Financial Reporting Standard applicable in the UK and Republic of Ireland' (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:
-give a true and fair view of the state of the company's affairs as at 31 December 2024 and of its loss for the year then ended;
-have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and
-have been prepared in accordance with the requirements of the Companies Act 2006.

Basis for opinion
We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditors' responsibilities for the audit of the financial statements section of our report. We are independent of the company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC's Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Material uncertainty related to going concern
The company's activities generated a loss of £277,110 and has a net liability of £3,126,985. The company's operational existence is still dependent on the ability to raise further funding from its parent company and other group members.

After making due enquires, the directors have formed a judgement that there is a reasonable expectation that the company can secure further adequate resources to continue in operational existence for the foreseeable future and that adequate arrangements will be in place to enable the settlement of their financial commitments, as and when they fall due.

For this reason, the directors continue to adopt the going concern basis in preparing the financial statements. Whilst there are inherent uncertainties in relation to future events, and therefore no certainty over the outcome of the matters described, the directors consider that, based upon the financial projections and dependent upon the success of their efforts to complete these activities, the company will be a going concern for the next twelve months.

Other information
The directors are responsible for the other information. The other information comprises the information in the Strategic Report and the Report of the Directors, but does not include the financial statements and our Report of the Auditors thereon.

Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.

Report of the Independent Auditors to the Members of
Petrotechnical Data Systems Limited


Opinions on other matters prescribed by the Companies Act 2006
In our opinion, based on the work undertaken in the course of the audit:
- the information given in the Strategic Report and the Report of the Directors for the financial year for which the financial statements are prepared is consistent with the financial statements; and
- the Strategic Report and the Report of the Directors have been prepared in accordance with applicable legal requirements.

Matters on which we are required to report by exception
In the light of the knowledge and understanding of the company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic Report or the Report of the Directors.

We have nothing to report in respect of the following matters where the Companies Act 2006 requires us to report to you if, in our opinion:
- adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or
- the financial statements are not in agreement with the accounting records and returns; or
- certain disclosures of directors' remuneration specified by law are not made; or
- we have not received all the information and explanations we require for our audit.

Responsibilities of directors
As explained more fully in the Statement of Directors' Responsibilities set out on page five, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the directors are responsible for assessing the company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the company or to cease operations, or have no realistic alternative but to do so.

Auditors' responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue a Report of the Auditors that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below.

Our approach to identifying and assessing the risks of material misstatement in respect of irregularities, including fraud and non-compliance with laws and regulations, was as follows:
- the engagement partner ensured that the engagement team collectively had the appropriate competence, capabilities and skills to identify or recognise non-compliance with applicable laws and regulations;
- we identified the laws and regulations applicable to the company through discussions with directors and other management, and from our commercial knowledge and experience of the company's operating sector;
- we focused on specific laws and regulations which we considered may have a direct material effect on the financial statements or the operations of the company, including the Companies Act 2006, taxation legislation and data protection, anti-bribery, employment, environmental and health and safety legislation;

Report of the Independent Auditors to the Members of
Petrotechnical Data Systems Limited

- we assessed the extent of compliance with the laws and regulations identified above through making enquiries of management and inspecting legal correspondence; and
- identified laws and regulations were communicated within the audit team regularly and the team remained alert to instances of non-compliance throughout the audit.

We assessed the susceptibility of the company's financial statements to material misstatement, including obtaining an understanding of how fraud might occur, by:
- making enquiries of management as to where they considered there was susceptibility to fraud, their knowledge of actual, suspected and alleged fraud; and
- considering the internal controls in place to mitigate risks of fraud and non-compliance with laws and regulations

To address the risk of fraud through management bias and override of controls, we:
- performed analytical procedures to identify any unusual or unexpected relationships;
- tested journal entries to identify unusual transactions;
- assessed whether judgements and assumptions made in determining the accounting estimates set out in the financial statements were indicative of potential bias; and
- investigated the rationale behind significant or unusual transactions.

In response to the risk of irregularities and non-compliance with laws and regulations, we designed procedures which included, but were not limited to:
- agreeing financial statement disclosures to underlying supporting documentation;
- reading the minutes of meetings of those charged with governance;
- enquiring of management as to actual and potential litigation and claims; and
- reviewing correspondence with HMRC, relevant regulators including the Health and Safety Executive, and the company's legal advisors.

Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation.

A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at www.frc.org.uk/auditorsresponsibilities. This description forms part of our Report of the Auditors.

Report of the Independent Auditors to the Members of
Petrotechnical Data Systems Limited


Use of our report
This report is made solely to the company's members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the company's members those matters we are required to state to them in a Report of the Auditors and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company's members as a body, for our audit work, for this report, or for the opinions we have formed.

Significant judgements and estimates
In the application of the Company's accounting policies, the directors are required to make judgements, estimates and assumptions about the carrying amount of the assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimates is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

Critical judgements
The following judgements (apart from those involving estimates) have had the most significant effect on amounts recognised in the financial statements.

Revenue recognition
Revenue is recognised upon the date of the provision of services or from the agreement of the contract. The directors consider that this is when it is probable that the economic benefits associated with the provision of the service will flow to the entity.

Tangible assets
The directors determine whether there are indicators of impairment on the company's tangible assets. Factors taken into consideration in reaching such a decision include changes in market prices and expected future financial performance of the asset.

Key sources of estimation uncertainty
The estimates and assumptions which have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities are as follows.

Computer equipment
Tangible fixed assets are depreciated over their useful lives taking into account residual values, where appropriate. The actual lives of the assets and residual values are assessed annually and may vary depending on a number of factors. In reassessing asset lives and residual value assessments, the directors consider issues such as future market conditions, the remaining life of the asset and projected disposal values.

Loans and borrowings
Loans and borrowings are initially recognised at the transaction price including transaction costs. Subsequently, they are measured at amortised cost using the effective interest rate method, less impairment. If an arrangement constitutes a finance transaction it is measured at present value.

Revenue
Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Company and the revenue can be reliably measured. Revenue is measured at the fair value of the consideration received, excluding discounts, rebates and value added tax.

Revenue is recognised for software, consultancy and ancillary services as those services are provided to customers.

Tangible fixed assets
Depreciation is provided at the following annual rates in order to write off each asset over its estimated useful
life.

Computer equipment - 18% -33.33% on cost

Financial instruments
Cash and cash equivalents
Cash and cash equivalents comprises cash on hand and all deposits, and other short-term highly liquid investments that are readily convertible to a known amount of cash and are subject to an insignificant risk of change in value.

Foreign currency transactions and balances
Transactions in foreign currency are initially recorded at the functional currency rate prevailing at the date of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated into the respective financial currency of the entity at the rate prevailing on the reporting period date. Non-monetary items carried at fair value that are denominated in foreign currencies are retranslated at the rates prevailing on the initial transaction dates. Non-monetary items measured in terms of historical cost in a foreign currency are not retranslated.


Trade debtors
Trade debtors are amounts due from customers for merchandise sold or services performed in the ordinary course of business. Trade debtors are recognised initially at the transaction price. They are subsequently measured at amortised cost using the effective interest method less provision for impairment. A provision for the impairment of trade debtors is established when there is objective evidence that the company will not be able to collect all amounts due according to the original terms of the receivables.


Trade creditors
Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Accounts payables are classified as current liabilities of the company does not have an unconditional right at the end of the reporting period to refer settlements of the creditor for at least twelve months after the reporting date. If there is an unconditional right to defer settlements for at least twelve months after the reporting date they are presented as non-current liabilities. Trade creditors are recognised initially at the transaction price and subsequently measured at amortised cost using the effective interest method.

Borrowings
Interest-bearing borrowings are initially recorded at fair value, net of transaction costs. Interest-bearing borrowings are subsequently carried at amortised cost, with the difference between the proceeds, net of transaction costs, and the amount due on redemption being recognised as a charge to the Profit and Loss Account over the period of the relevant borrowing. Interest expense is recognised on the basis of the effective interest method and is included in interest payable and similar charges. Borrowings are classified as current liabilities unless the Company has an unconditional right to defer settlement of the liability for at least twelve months after the reporting date.

3. ACCOUNTING POLICIES - continued
Taxation
Taxation for the year comprises current and deferred tax. Tax is recognised in the income statement except to the extent that it relates to items recognised in order comprehensive income or directly in equity.

Current or deferred taxation assets and liabilities are not discounted.

Current tax is recognised at the amount of tax payable using the tax rates and laws that have been enacted or substantive enacted by the balance sheet date.

Deferred tax
Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the statement of financial position date.

Timing differences arise from the inclusion of income and expenses in tax assessments in periods different from those in which they are recognised in financial statements. Deferred tax is measured using tax rates and laws that have been enacted or substantively enacted by the year end and that are expected to apply to the reversal of the timing difference.

Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits.

Research and development
Expenditure on research and development is written off in the year in which it is incurred.


Foreign currencies
Assets and liabilities in foreign currencies are translated into sterling at the rates of exchange ruling at the statement of financial position date. Transactions in foreign currencies are translated into sterling at the rate of exchange ruling at the date of transaction. Exchange differences are taken into account in arriving at the operating result.

Going concern
The company's activities generated a Loss of £277,110 (December 2023: £151,159 loss) and has a net liability of £3,126,985 (December 2023: net liability of £2,849,875). The company's operational existence is still dependent on the ability to raise further funding from its parent company and other group members.

After making due enquires, the directors have formed a judgement that there is a reasonable expectation that the company can secure further adequate resources to continue in operational existence for the foreseeable future and that adequate arrangements will be in place to enable the settlement of their financial commitments, as and when they fall due.

For this reason, the directors continue to adopt the going concern basis in preparing the financial statements. Whilst there are inherent uncertainties in relation to future events, and therefore no certainty over the outcome of the matters described, the directors consider that, based upon the financial projections and dependent upon the success of their efforts to complete these activities, the company will be a going concern for the next twelve months.

Provision
Provisions are recognised when the company has a present obligation (legal or constructive) as a result of a past event, it is probable that the company will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period, taking into account the risks and uncertainties surrounding the obligation. Where the effect of the time value of money is material, the amount expected to be required to settle the obligation is recognised at present value using a pre-tax discount rate. The unwinding of the discount is recognised as a finance cost in profit or loss in the period it arises. The Company recognises a provision for annual leave accrued by employees as a result of services rendered in the current period, and which employees are entitled to carry forward and use within the next 12 months. The provision is measured at the salary cost payable for the period of absence.

Leases
Rentals payable and receivable under operating leases are charged to the profit and loss account on a straight line basis over the period of the lease.

Employee benefits
When employees have rendered service to the company, short-term employee benefits to which the employees are entitled are recognised at the undiscounted amount expected to be paid in exchange for that service.

The company operates a defined contribution plan for the benefit of its employees. Contributions are expensed as they become payable.

Impairment
Assets not measured at fair value are reviewed for any indication that the asset may be impaired at each balance sheet date. If such indication exists, the recoverable amount of the asset, or the asset's cash generating unit, is estimated and compared to the carrying amount. Where the carrying amount exceeds its recoverable amount, an impairment loss is recognised in profit or loss unless the asset is carried at a revalued amount where the impairment loss is a revaluation decrease.

4. TURNOVER

The turnover and loss before taxation are attributable to the one principal activity of the company.
