Sino Gas & Energy Holdings Limited has announced that a flow rate of 2.1 million ft3/d has been recorded from an upper zone of the LXDG-04 exploration well.
Exploration well LXDG-04 tested at 2.1 million ft3/d from an upper zone in the prospective exploration area of the Linxing (East) Production Sharing Contract (PSC). This stable flow rate was recorded at a wellhead tubing pressure of 760 psi over a period of 48 hours and is in addition to the rate of over 600 000 ft3/d recorded in a middle lower zone previously announced in the 3Q15 Activities Report.
Sino Gas estimates LXDG-04 could produce over 3 million ft3/d at standard field operating pressures. Linxing (East) first reserve bookings expected in year-end reserve assessment LXDG-04 exploration well is the third well in the Linxing (East) exploration area to yield production test flow rates above commercial thresholds following positive flow tests achieved on LXDG-03 and LXDG-05.
LXDG-02 is currently being tested. In addition, as previously announced, good log results have been received from LXDG-06 with 57.8 m of net pay identified. LXDG-07 and LXDG-08 are currently drilling and, if successful, is planned to be tested in 2016 along with LXDG-06.
In Sino Gas' most recent independent reserve and resource report assessment, RISC estimated 924 billion ft3 of gross deep gas P50 Prospective Resources in the Linxing (East) area (276 billion ft3 net to Sino Gas), based on a prospective area of 334 km2 as at 31 December 2014. From the results discussed above, Sino Gas expects the forthcoming assessment as at 31 December 2015 will result in the conversion of a portion of the prospective resources into the first reserve bookings for the Linxing (East) area.
The estimated quantities of petroleum that may potentially be recovered by the application of a future development project(s) relate to undiscovered accumulations. These estimates have both an associated risk of discovery and a risk of development. Further exploration appraisal and evaluation is required to determine the existence of a significant quantity of potentially moveable hydrocarbons.
