Energean PLC will drill additional structures after making a commercial discovery at the Hermes exploration well, offshore Israel. Preliminary estimates show 7-15 billion cu m (bcm) of recoverable natural gas resources. The discovery also de-risks the nearby Poseidon and Orpheus structures.
Detailed analysis of the data collected by the well is ongoing, with the aim of refining volumetric estimates and potential commerciality for both the discovery and the full area.
The well was drilled on Block 31 by the Stena IceMAX drilling rig which has now moved to Block 12 (Olympus area) to drill the Zeus structure about 20 km from Karish and 20 km from Tanin A, in a water depth of 1,769 m (OGJ Online, May 9, 2022).
Zeus is estimated to contain 10-12 bcm of gross prospective unrisked gas resources in the A/B/C sands and will enable Energean to gather additional data for refined resource estimates across the entire Olympus area, which is currently estimated at about 58 bcm of unrisked recoverable resources.
Energean has exercised its option to drill a sixth well with Stena Drilling Ltd. as part of its current drilling campaign. This well is expected to target the Hercules prospect, Block 23, offshore Israel.
