United Oil & Gas achieves further success at Abu Sennan licence

United Oil & Gas has reported that, following the drilling of the Al Jahraa-8 (AJ-8) development well in the Abu Sennan concession, onshore Egypt, initial interpretations indicate a total of over 40 m MD of net oil pay across three different reservoir units in a sidetrack (AJ-8ST1), after the initial hole was plugged back due to stability issues.

United holds a 22% working interest in the licence, which is operated by Kuwait Energy Egypt.

The AJ-8 well commenced drilling on 2 May, targeting the Abu Roash and Bahariya reservoirs in an undrained portion of the Al Jahraa field. After drilling through the Upper Bahariya and reaching 4071 m MD, inflow into the well was observed. The well was brought under control, but due to hole conditions in the highly deviated well, a decision was made to plug the well back above the ARC, and drill a sidetrack.

Preliminary interpretations indicate the sidetrack encountered net pay in the AR-E, and over 30 m of net pay across the Upper Bahariya and Lower Bahariya Upper reservoirs. Due to hole conditions in the sidetrack, a decision was made to run liner at 4314 m MD and TD the well without reaching the Lower Bahariya Lower reservoir that had been a pre-drill target.

With initial interpretations suggesting over 40 m net pay encountered, the Al Jahraa-8 well has further demonstrated the potential within the currently producing fields of the Abu Sennan licence. In particular, the net pay that was encountered in the Upper Bahariya is above pre-drill expectations.

The well now be completed and tested across the three hydrocarbon-bearing reservoirs.

After completing the AJ-8 well, the EDC-50 rig will move c.7 km to the north of the Al Jahraa field to drill the ASX-1X exploration well. This is a similar structure to the nearby discovery that was recently made at ASD-1X, with targets in the Khoman, Abu Roash and Bahariya reservoirs.

This is expected to be the final well of the 2021 campaign, with longer-term plans for unlocking the additional potential that exists in the Abu Sennan licence currently under discussion.
