UK-based United Oil & Gas and its partners have made an oil discovery at the Al Jahraa-8 (AJ-8) development well located in the Abu Sennan concession onshore Egypt.

Based on interpretations, the well has a total of over 40m of net oil pay across three different reservoir units in a sidetrack (AJ-8ST1).

United Oil & Gas said that the well is estimated to have more than 30m of net pay in two reservoirs, the Upper and Lower Bahariya, based on the preliminary results. This represents significantly above pre-drill expectations.

Drilling at the AJ-8 well, which started in May 2021, was targeted at the Abu Roash and Bahariya reservoirs in an undrained portion of the Al Jahraa field.

However, the inflow was into the well was observed following drilling to a measured depth of 4,071m through the Upper Bahariya, the firm said.

Although the well was brought under control, the partners have decided to plug the well back above the ARC and drill a sidetrack due to stability issues.

United Oil & Gas CEO Brian Larkin said: “This latest success from the AJ-8 development well will not only provide an uplift to our low-cost production base but also demonstrates the deeper potential that exists within the Bahariya Formation targets.”

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

According to pre-drill expectations, the Abu Roash E (AR-E) reservoir at the development well also ‘appears to have encountered net pay’.

United Oil & Gas said it has added a fully funded exploration well (ASX-1X) to the 2021 drilling schedule as a result of continued success at the Abu Sennan license.

Targeting multiple Abu Roash and Bahariya reservoirs, the ASX-1X exploration well is planned to be drilled using the EDC-50 rig following the completion of AJ-8 well operations.

Kuwait Energy Egypt operates the license with a 25% stake while United owns a 22% stake. Other partners include Global Connect (25%) and Dover Investments (28%).
