Randeep Grewal, Chairman and Chief Executive of Greka Drilling, commented:

"China's undisputed vast resource of unconventional gas is the prize, the attainment of which has been thwarted by the lack of specific technology and aptitude to commercially extract this resource. In effect there are today and have been others previously, many 'gold diggers without the right shovels'. Converting the resource into reserves and hence revenue involved the development of the required technology to drill in the very complex, under-saturated, brittle, and heavily faulted coal beds with the world's highest gas content.

It took materially longer than we initially anticipated to unlock the unconventional gas resource potential, but unlock it we did and now our committed fleet expansion from 7 to 32 rigs makes us the largest dedicated unconventional gas driller within China and we have an ambition to be the same across Asia through continued expansion in the future."

Chairman's Statement

This is Greka Drilling's fourth year of operation and the first year as a public Company following the demerger from Green Dragon and listing on 8 March of this year. This demerger was designed to set us apart as a specialised unconventional gas driller capable of utilizing our drilling methodology for third parties as well as for Green Dragon. The Company's demerger was additionally intended to position the Company to capitalize on our first mover advantage and the growing demand for domestic unconventional gas production in China. All of which we believe we have successfully achieved in the first half.

China's undisputed vast resource of unconventional gas is the prize, the attainment of which has been thwarted by the lack of specific technology and aptitude to commercially extract this resource. In effect there are today and have been others previously, many "gold diggers without the right shovels". Hence, the value of this resource is far less reliable and predictable due to a lack of effective ability to convert the resource into reserves and hence revenue. Green Dragon acknowledged this void during its "long march" through the development of the required technology to drill in the very complex, under-saturated, brittle, and heavily faulted coal beds with the world's highest gas content. Our mission was to develop a scalable and repeatable methodology that overcame the geological issues associated with the strata.

It took materially longer than we initially anticipated to unlock the unconventional gas resource potential due to the required technology development, but unlock it we did. Green Dragon initially established its in-house drilling division out of necessity and, once the technology was mature, its need was to achieve gas production rather than to own the drilling services business which accordingly was demerged.

Our committed fleet expansion from 7 to 32 rigs makes us the largest dedicated unconventional gas driller within China and we have an ambition to be the same across Asia through continued expansion in the future.

Operationally, the organization is busy: drilling with all seven rigs running 24/7; hiring an additional 400 staff to man the upcoming new rig deliveries, with the first GD75-1 rig going into service this month and the balance 24 over the coming months; constructing a new staff complex in the field to accommodate up to 1,500 staff; commencing a stringent training program to ready the new staff; and concurrently adding the management and administration capacity required by this growth. It is indeed a very busy time!

Concurrently, discussions with potential third party customers have already begun. The majors in China are spending billions on overseas acquisitions aimed primarily at bringing technologies that will help in unlocking China's vast unconventional gas resource. As Greka Drilling is able to provide this acutely needed technology domestically now, it is unsurprising that unlike any other drilling contractor, we are experiencing significant demand for our drilling services from third parties. We expect that as our fleet expands and capacity becomes available we will selectively offer our services to this broader clientele. In line with the overall demand for energy in China, the demand for our services far exceeds our capacity and I expect this situation to continue for several years to come.

I look forward to leading the Company in this exciting growth with our tireless employees and management eager to achieve an ever higher plateau of operational and financial success. The Company is achieving this exciting growth profitably with a strong balance sheet. A discipline we intend to maintain.

Notes to Condensed Interim Financial Statements

1. GENERAL INFORMATION

The consolidated unaudited interim financial information set out in this report is based on the consolidated financial statements of Greka Drilling and its subsidiary companies (together referred to as the "Group"). The condensed consolidated financial information should be read in conjunction with the annual financial statements for the year ended 31 December 2010, which have been prepared in accordance with International Financial Reporting Standards (IFRS and IFRIC interpretations) issued by the International Accounting Standards Board except for IAS 34. The financial statements of the Group for the 6 months ended 30 June 2011 were approved and authorised for issue by the Audit Committee and the Board on 6 September 2011.

2. ACCOUNTING POLICIES

The condensed financial information for the six months ended 30 June 2011 and 30 June 2010 is unaudited and does not constitute the Group's statutory financial statements for those periods. The comparative financial information for the full year ended 31 December 2010 has, however, been derived from the financial statements for that period which are included in Group's admission document. The auditors' report on those accounts was unqualified.

Basis of preparation

After making enquiries, the directors have a reasonable expectation that the Company and the Group have adequate resources to continue in operational existence for the foreseeable future. Accordingly, they continue to adopt the going concern basis in preparing the half-yearly condensed financial statements.

The financial information is presented in United States dollars and all values are rounded to the nearest thousand dollars (US$'000) except when otherwise indicated.

The entities which comprise the Group did not include an overall holding company and did not form a legal group in the periods before 8 March 2011. However they have been under common management and control in those years. The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Company (its subsidiaries). Control is achieved where the Company has the power to govern the financial and operating policies of an invested entity so as to obtain benefits from its activities. The results of subsidiaries acquired or disposed are included in the consolidated income statement from the effective date of acquisition or up to the effective date of disposal, as appropriate.

International Financial Reporting Standards as adopted by the European Union ("IFRSs") do not provide for the preparation of combined financial information and accordingly in preparing the combined financial information certain accounting conventions commonly used for the preparation of historical financial information for inclusion in investment circulars as described in the Annexure to SIR 2000 (Investment Reporting Standard applicable to public reporting engagements on historical financial information) issued by the UK Auditing Practices Board have been applied. The application of these conventions results in the following material departures from IFRSs. In other respects IFRSs have been applied.

The combined financial information has been prepared by aggregating the assets, liabilities, results share capital and reserves of the relevant entities, after eliminating intercompany transactions, balances and unrealised gains on transactions between the combined entities. Consequently it is not meaningful for the Company to present share capital. Instead "Capital reserve" is presented which represents the aggregated share capital and share premiums and capital reserves of the companies making up the Group.

The combined financial information has been prepared in accordance with the requirements of the AIM Rules for Companies and in accordance with this basis of preparation. The basis of preparation describes how the financial information has been prepared in accordance with IFRSs except as described above.

Except as described above, the financial information has been prepared in accordance with IFRSs as adopted by the European Union, that are effective for accounting periods beginning on or after 1 January 2010. The principal accounting policies adopted in the preparation of the financial information are set out below. The policies have been consistently applied to all the years presented, unless otherwise stated.

The preparation of financial information in conformity with IFRSs requires the use of certain critical accounting estimates. It also requires management to exercise its judgment in the process of applying the Group's accounting policies. The areas involving a higher degree of judgment or complexity or areas where assumptions and estimates are significant to the financial information are disclosed in note 2 to the financial information. Actual results may differ from these estimates.

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

3. REVENUE AND SEGMENTAL INFORMATION

The Group has one reportable segment as set out below. The operating results are regularly reviewed by the Group's chief operating decision-makers ("CODMs") that are used to make strategic decisions.

Drilling services revenue represents the net invoiced value of contract drilling services provided to one customer. The amounts of each significant category of revenue recognised during the periods ended 30 June 2011, 31 December 2010 and 30 June 2010 are as follows:

4. FINANCE INCOME

5. FINANCE COSTS

6. TAXATION

Taxation for the Group's operations in the PRC is provided at the applicable current tax rate of 25% on the estimated assessable profits for the period.

The reasons for the difference between the actual tax charge for the periods and the standard rate of corporation tax in the Cayman Islands applied to the (loss)/profit for the periods are as follows:

7. EARNINGS PER SHARE

Basic earnings per share is based on the profit after taxation of US$405,000 (first half 2010: loss for the period, US$899,727) and the weighted average number of 398,245,758 ordinary shares in issue during each period.

In accordance with IAS 33 the weighted average number of shares for prior periods has been adjusted as if the Group reconstruction occurred at 1 January 2010.

8. PROPERTY, PLANT AND EQUIPMENT

During the period, the Group incurred approximately US$2,165,663 on additions to plant and equipment (30 June 2010 - US$72,220, 31 December 2010 - US$3,108,985).

9. DEFERRED TAXATION

There were no unrecognised deferred tax assets or liabilities in the period.

10. INVENTORIES

11. TRADE AND OTHER RECEIVABLES

12. TRADE AND OTHER PAYABLES

13. LOANS AND BORROWINGS

The bank borrowings are fully repayable within eight months of the end of each reporting period and are secured on the Group's building situated in Zhengzhou.

14. SHARE CAPITAL AND CAPITAL RESERVE

On 7 February 2011 Greka China Ltd subscribed for one share for a subscription price of US$50m.

On the same date 398,245,757 shares were transferred to Green Dragon Gas credited as fully paid. On 8 March 2011 these shares were distributed by Green Dragon Gas to their shareholders.

On 15 February 2011 the inter group balances owing to Green Dragon Gas and its subsidiaries amounting to US$27.2m was capitalized into one share of Greka Technical Services ("GTS"), a subsidiary. This share was then transferred to the company.

15. RELATED PARTY TRANSACTIONS

Saved as disclosed in notes 11, 12 and 14, there were no other related party transactions that are required to be disclosed. Transactions between the Company and its subsidiary undertakings which are related parties, have been eliminated on consolidation and are not disclosed in this note.
