Exillon announced that the appraisal well EWS-31 and production well EWS-34 have successfully found oil on a far eastern margin and western part of the EWS I field.
EWS - 31
The EWS-31 well, which was spudded on March 30, 2010, was designed to test an eastern margin of the EWS I field. The well flowed water-free oil naturally to the surface with a flow rate of 960 bbl/day on a 10 mm choke, and was drilled on a turn-key contract in 23 days for a total consideration of just $1.19 million. The well reached target depth within the Jurassic P reservoir at 1844 - 1850m, confirming the presence of 5.9 m of net oil pay within the Jurassic.
The well was drilled directionally 0.9 km to the north-east from the existing well pad 30 on the EWS I field, and is now being connected to existing production facilities.
EWS - 34
The EWS-34 well, which was spudded on March 25, 2010, was drilled on the western part of the EWS I field on a turn key contract in 22 days for a total consideration of just $0.98 million. The new well encountered the main producing Jurassic P reservoir at 1,807m. Results of wire line logging combined with oil shows and sample analysis while drilling, have confirmed the presence of 6.2m of net oil pay within the Jurassic. Testing of the Jurassic interval in the well will be completed by the end of May.
The EWS-34 well has also encountered the Pre Jurassic reservoir at 1817m. The well flowed water-free oil naturally to the surface with a flow rate of 320 bbl/day on an 8 mm choke from the Pre-Jurassic zone.
The well was drilled directionally 1.4 km to the east from the existing well pad 3 on the EWS I field. On completion of testing of the Jurassic interval the well will be connected to existing production facilities.
The Group has achieved 100% drilling success rate across three wells drilled in 2010, and is on schedule to complete ongoing drilling program.
