The EWS-31 well, 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 10mm choke, and was drilled on a turn-key contract in 23 days for a total consideration of just $1.19m.
The well reached target depth within the Jurassic P reservoir at 1844mt – 1850mt, confirming the presence of 5.9mt of net oil pay within the Jurassic.
The well was drilled directionally 0.9km to the north-east from the existing well pad 30 on the EWS I field, and is now being connected to existing production facilities.
The EWS-34 well, 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 $0.98m. The new well encountered the main producing Jurassic P reservoir at 1,807mt.
Results of wire line logging combined with oil shows and sample analysis whilst drilling, have confirmed the presence of 6.2mt 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 1817mt. The well flowed water-free oil naturally to the surface with a flow rate of 320 bbl/day on an 8mm choke from the Pre-Jurassic zone.
The well was drilled directionally 1.4km 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.
