Delek Group subsidiary, Delek Energy, has announced that its subsidiaries, Delek Drilling and Avner Oil Exploration, have made a natural gas discovery under the Matan license at the Tamar-1 drilling prospect offshore Israel.

Noble Energy Mediterranean said that the drill conducted in approximately 1,680m depth of water, reached a total depth of 4,900m.

Formation logs, which were created as part of the drilling process, identified three reservoirs which included sand layers with a net total of more than 140m of natural gas. The thickness and quality of the reservoirs encountered were greater than the operator previously anticipated at this drill location, said Delek Energy.

According to the operator, initial indications show that the gas reserves identified in the well are substantial, equal to the pre-drill estimated gross mean resources of approximately 3.1 trillion cubic feet. The operator estimates that subject to the collection of additional data, the reserve estimate for Tamar could further increase.

The partners in the Tamar drill have decided to conduct drill extraction targets tests to establish the well’s daily natural gas production potential. The production tests are expected to continue for approximately three weeks, and are estimated to cost $20 million.
