P2437 is a 30th Round licence situated in the Rotliegend aged Lower Leman Sandstone play fairway, on the eastern edge of the Sole Pit Inversion. The Lower Leman Sandstone is the principle and proven petroleum system in the basin with offset fields including Barque, Mimas and West Sole.  One discovery has been made on the block (Sloop) which was drilled by well 48/08a-1. Three other prospects have been identified by previous operators.

Sloop Discovery

Well 48/08A-1 well discovered Sloop in 1989, a Lower Leman gas bearing sand in a heavily faulted structure. A 209.7m gross Leman Sandstone was encountered with certain sections reaching 12% porosity. Log analysis suggests a gas-water contact at 2908m TVDSS. The discovery has a gas initially in place of 17 to 54 BCF.

Selene Prospect

The Selene prospect is located on the northern limb of the Sole Pit Basin inversion axis and takes the form of a NW-SE elongated closure. The prospect is formed by two south-west dipping fault blocks, truncated at the NW region by De Keyser faults running SW-NE.

Well 48/08b-2 was drilled down-dip of the Selene prospect and was drilled near or on major faults, attributing to its lower reservoir quality than regional trends. During uplift these faults likely transmitted pore fluids saturated with carbonates etc. from Z1 and Z2 directly above the Rotliegendes, which led to both ferroan and non ferroan dolomite precipitating into the reservoir, resulting in 48/08b-2 to be a classed as a dry well despite seeing up to 4.9% gas peaks in the Leman Sandstone.

Endymion Prospect

Straddling block 48/08b and block 48/03 the Endymion prospect is a structural closure at Leman Sandstone. The structure is formed by the extension of the fault system that controls the Mimas field on strike to the southeast and is separated by a graben from Mimas, therefore likely to be an offset to Mimas. In addition, the proximity to infrastructure enables opportunities for a tie-back option.

Rig and Jib Leads

The Rig and Jib Prospect is a three-way dip closure against north-west trending normal faults. The Rig and Jib Prospect can be separated into two separate culminations. The Rig Prospect independently has an aerial closure of approximately 8km2, in comparison the Jib prospect has an area of 4km2.
