CUSTOMER OVERVIEW

·Green Dragon Gas, historically the largest client, curtailed its drilling program in the first half of the year until the favorable conclusion of its title issues. These have now been resolved and the Company has recommitted itself to reaching its production targets of 18bcf.

·CNPC Huabei Changzhi (CBM) has planned to drill 300 wells in its Anze Block, Shanxi Province. A total of 110 are targeted for this year. Of this program, the Company has completed two directional wells till date. In addition, an exploration well will be drilled by rig GD75-21 and a Horizontal well will be drilled by rig GD75-25. Following the results of these two wells, the Company expects to be awarded an additional 70 wells planned by CNPC Huabei Changzhi from their total program for this year.

·CNPC Huabei Jincheng (CBM) has contracted the Company to drill at its Jincheng Block, Shanxi Province in two locations. The Company successfully completed a LiFaBriC well earlier in the year which is currently on production and being evaluated. Presently, the Company is drilling a four directional well program using GD75-23, of which the second directional is currently being drilled.

·Sinopec Huadong CBM (BOFA) contracted the Company for one year program to drill 50 wells at Jixian, Shanxi Province. Sinopec Huadong CBM has a 3,000 well program with 600 wells in total planned for this year. Rig GD75-22, supported by Rig GS685-2, has completed three wells till date and the fourth is being currently drilled. During these test wells, the Company's performance continued to improve. The TVD for the third well was 1,214 m and the MD was 1,292 m. This was achieved in 10 days from spud to completion and compares with 19 days for the first, with a TVD of 1,225 m and MD 1,341 m. The Company expects to continue the drilling program and, subject to agreement with the client on drilling locations, drill the balance of the one year program as planned.

·Sinopec Huabei (Petroking) has planned for a 50 well program during the current exploration phase for unconventional oil within the Xunyi Block, Shaanxi. The Company is under contract to drill 100 wells subject to successful drilling of the first 20 drilled across the Sinopec Huabei acreage inclusive of the Xunyi Block. The Company¡¯s GD75-12 and GD75-14 are currently drilling under this program. Rig GD75-14 has completed one directional well and is currently drilling the second directional well of a seven well program. Additionally, GD75-12 spud the first Horizontal Well on 1st August which is currently being drilled in co-operation with Sinopec engineers.

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

"Our objective of diversifying the client base was well executed with current drilling activities progressing under five different customer contracts.

Notwithstanding the positive transition to a diverse client base, our historically predominant client, Green Dragon Gas, curtailed its drilling program. This negatively impacted our first half results but we are pleased that they have re-engaged in their programme, using Greka Drilling as their drilling partner. Whilst the success achieved in diversifying away from a single client has been a success, the time taken to fully capitalize on the increased customer base did not offset the effects of losses from the drilling campaign from the first customer. We expect to continue into 2014 with this diversified client base and a strong backlog."

CHAIRMAN'S STATEMENT

This year will be remembered as a year of transition and growth for the Company towards its independence from its predecessor parent Green Dragon. The transition, as with most, requires managing the related collateral issues which is precisely what the business did during the first half and will continue to during the course of rest of this year.

The Company did very well in penetrating the Chinese E&P market and is quickly being acknowledged as a viable drilling contractor with an environmentally progressive, and technologically advanced efficient drilling service. Our rigs are currently on China National Petroleum Corporation, Sinopec and Petrochina blocks which are the three largest on-shore E&P companies in China. Within this diverse customer base, we are drilling Coal Bed Methane vertical, directional, horizontal and LiFaBriC wells as well as directional and horizontal wells in Shale Oil & Gas. These clients have continuous large drilling campaigns across their various assets and thus the initial acceptance of Greka Drilling this year on a trial basis presents the foundation for significant growth potential in the years to come.

Our transition from a single client, Green Dragon, onto a broader client base and varied geologies is complete. The technical aptitude and competency of the Company's staff and equipment has been proved.

Notwithstanding the positive transition to a broader client base, our historically predominant client curtailed its drilling program which negatively impacted our first half results. In essence, the single client exposure crystallized and whilst we have gained new clients, the scale of the new business was not sufficient to offset the fall in Green Dragon's drilling

We expect the trial and exploration activities for our new clients to continue rest of this year as they did during the first half. We expect to enter 2014 with a significant backlog with all our five clients which is expected to be diversified in geology, geography and drilling service. We look forward to such diversification to mitigate concentration risk and achieve a higher utilization rate from our drilling rigs next year than in this transitional year.
