ADX Energy (ASX: ADX) has estimated 51 million barrels of mean contingent oil in place at Sidi Dhaher-1 in Tunisia, after completing the operator's revised mapping and volume calculations.
These calculations were made using a new seismic interpretation integrating well results from the recent Sidi Dhaher well.
ADX Energy said subsequent down hole pressure measurements and sampling confirmed the presence of an oil column.
The Sidi Dhaher discovery encountered a thick, porous and permeable Bireno reservoir of upper Cretaceous age overlaid with an 80 m sealing shale section. Subsequent down hole pressure measurements and sampling confirmed the presence of an oil column.
The company is currently finialising rig selection, which will then allow well testing to begin.
The Sidi Dhaher discovery is located in the 2,428 square kilometre Chorbane Exploration Permit in onshore central Tunisia near the port city of Sfax, and increasing the prospectivity it is surrounded by several producing oil fields and extensive oil and gas infrastructure.
