Exillon Energy plc is pleased to announce that well EWS-35 and well EWS-101 have successfully found oil on an eastern part of the East EWS I field and on a north-eastern part of the EWS II field.
EWS – 35
The EWS-35 well, which was spudded on 23 April 2010, was drilled on an eastern part of the East EWS I field. The well flowed water-free oil naturally to the surface with a flow rate of 470 bbl/day on a 12 mm choke. Whilst the average net oil pay within the East EWS I field according to the Miller and Lents May 2010 reserves report is 8.2 m this new well has 14.6m of net pay within the Jurassic. The well reached target depth within the Jurassic P reservoir at 1837m.
The well was drilled directionally to the north-west from the existing well pad 30 on the East EWS I field, and is now being connected to existing production facilities. The well was drilled on a turn-key contract in 43 days for a total consideration of 1.7 million.
EWS – 101
The EWS-101 well, which was spudded on 26 May 2010, was drilled on the north-eastern part of the EWS II field on a turn-key contract in 18 days for a total consideration of $1.1 million. The new well encountered producing Jurassic J2-3 reservoir at 1957m, and producing Jurassic J4 reservoir at 1970m. Results of wire line logging have indicated the presence of 4.6m of net oil pay within the J2-3 horizon and 9m within the J4 horizon. Testing of the well will be completed in Q1 2011 due to the absence of infrastructure at the EWS II field.
Whilst the average net oil pay for the Jurassic reservoir within the EWS II field according to the Miller and Lents May 2010 reserves report is around 9m, this new well indicatively has 13.6m of net pay within the Jurassic.
The well was drilled directionally to the north-east from the existing well pad 1 on the EWS II field. On completion of testing of the Jurassic interval the well will be connected to production facilities.
The Group has achieved 100% drilling success rate across seven wells drilled in 2010, which is the result of the continued application of 3D seismic combined with a thorough understanding of reservoir geology.
