OSLO -- PA Resources has made an oil discovery at the Didon North prospect in the Zarat permit offshore Tunisia. The Didon North-1 exploration well was drilled to a total depth of 3,170 m (10,400 ft) and encountered 14 m (46 ft) of oil pay in the El Gueria formation.
The well was drilled to test two formations -- the El Gueria formation, which is a widely established reservoir formation in Tunisia including the producing Didon field, and the deeper Chouabine formation. The Chouabine formation is currently not a producing reservoir interval in Tunisia.
The top of the El Gueria formation was encountered at 2,797 m (9,176 ft) and the formation has excellent reservoir parameters, the company says. Porosities are in the range of 15 to 22%. Logging and pressure data across the reservoir interval and an oil sample prove the presence of an oil column of 14 m (46 ft). The company reports that the deeper situated Chouabine formation was found to be water bearing. Currently, the exploration well is being plugged and abandoned.
The recovered well data will be analyzed and reviewed in order to decide the next step for the exploitation of the Didon North discovery, the company says.
