STOCKHOLM, Sweden -- PA Resources has completed the drilling of a pilot hole as part of the development of new production wells on the Didon field in Tunisia. The pilot well confirmed excellent reservoir properties and proved a larger than expected vertical oil column, according to the company.
The Ensco 85 jackup drilled the pilot hole from the Didon platform, situated in the Gulf of Gabes, offshore Tunisia, to a reservoir location in the central parts of the Didon field. The pilot well was drilled to gather information on oil saturation and pressure across the reservoir section and serve as control for the drilling of the Didon-7 horizontal production drain.
The drilling of the pilot hole is now complete. The reservoir section came in higher than expected and the data gathered in the pilot hole has proven a larger than expected vertical oil column and confirmed the excellent reservoir quality expected in the area, according to PA Resources. The pilot well used the first section of the Didon-8 pilot well, which encountered a fault when it was drilled.
The pilot hole section will now be plugged before the horizontal production drain of the Didon-7 is drilled. The horizontal drain is planned to have a length of 550 m (1,804 ft) and will be placed along the top of the reservoir section. Once completed, the Didon-7 well is expected to increase the production significantly, according to PA Resources.
Following the drilling and completion of the Didon-7 production well, PA Resources will begin the drilling of the second production well targeting the western part of the field.
