STOCKHOLM, Sweden -- PA Resources has completed the Didon-7 production well as part of its development program on the Didon oil field in Tunisia. The jackup ENSCO 85 drilled a pilot hole and a horizontal producer, and conducted production tests. Following well testing, the Didon-7 has been put on regular production at 12,500 b/d of oil.
According to the company, the pilot hole encountered the top reservoir 5 m (16.4 ft) higher than predicted. Wireline logs and pressure data confirmed good reservoir properties and a 30-m (98-ft) oil column. The horizontal section was drilled high in the reservoir to maximize oil recovery. A 500-m (1,640-ft) long drain was completed within the two upper layers of the reservoir at a horizontal level of 2,714 m (8,904 ft). The drain showed that the structure is about 6 to 8 m (20 to 26 ft) higher than predicted in this area of the field.
The Didon-5 well, which was shut in prior to start-up of Didon-7, is currently being hooked up for production and it will be back online at the end of June.
