Sino Gas And Energy Holdings Limited (ASX:SEH) Signs Strategic Development Focused Agreement
Perth, Nov 23, 2011 AEST (ABN Newswire) - Sino Gas And Energy Holdings Limited (ASX:SEH) continues to move closer to the transition from explorer to developer in China following the signing of a Strategic Cooperation Framework Agreement (Agreement) with the Bohai Downhole Drilling Company (BHDC) relating to the development of the Sanjiaobei PSC project.

BHDC is a subsidiary of CNPC, the Chinese Oil and Gas major, and a full service provider of gas and oilfield services throughout China and in international markets. In particular BHDC has extensive experience delivering successful oil and gas projects in China including the Dagang and Huabei oil fields and the Sulige gas field, in cooperation with CNPC and international oil and gas major TOTAL.

During 2011, Sino Gas accelerated the appraisal activity on its Sanjiaobei PSC Project and recently announced a 153% increase in Reserves and Contingent and Prospective Resources on this Project to 1.15 Tcf. The increase raised Sino Gas's total Reserves, Contingent and Prospective Resources on all its Projects to 2.9 Tcf.

Sino Gas's Executive Chairman, Gavin Harper, said that the Company is currently working to complete the Chinese Reserves Report on the Sanjiaobei Project, and as part of completing the Overall Development Plan (ODP) has commenced extensive development planning. The Agreement with BHDC is a key step in that process and Sino Gas will benefit from the ability to undertake integrated planning and implementation of the Development.

Sino Gas's Chief Operating Officer, Frank Fu added "BHDC has already drilled 3 wells for Sino Gas and is currently completing the SJB2 well. We have been particularly impressed with their capability and professionalism and we welcome the opportunity to partner with BHDC and work closely with them in the development of the Sanjiaobei Project".

Significant Operational Success Continues

Sino Gas continues to achieve excellent operational success on its Linxing and Sanjiaobei Projects.

SJB2 well (Sanjiaobei PSC): now at total depth with multiple gas pay zones encountered Sino Gas has reached total depth on its SJB2 well as planned and is currently logging the well.

The initial analysis of the logs, which is subject to further review, has indicated the presence of gas in multiple pay zones consistent with Sino Gas's expectations. Side wall core samples will now be taken from these pay zones to enable Sino Gas to determine the most appropriate testing program for the well.

SJB1 well (Sanjiaobei PSC): initial flow back achieved after stimulation Sino Gas has now successfully fracture stimulated a lower pay zone in its SJB1 well and is flowing back the frac fluid from the zone to determine the stable gas rate.

Following the perforation of the zone, gas was observed at surface and Sino Gas's testing contractor CCDC Changqing Downhole Services Company proceeded with a hydraulic fracture stimulation as planned.

The well is currently flowing gas and continues to be 'flowed back' in order to remove the frac fluid from the formation. Forward operations are to continue to clean up and then to measure the gas flow and other sub-surface parameters.

TB10 well (Linxing PSC): drilling underway with current depth 550 meters Sino Gas is drilling the TB10 well on its Linxing Project to evaluate the same payzones that were encountered in the nearby TB06 well (initial flow estimated at around 1,000,000 scf/day).

Following the completion of the site preparation the well was spudded (drilling commenced) and the rig is currently at a depth of around 550 meters and drilling ahead.
