Noble Energy appraisal well hits gas offshore Cyprus
HOUSTON -- Noble Energy, Inc. has announced that the A-2 appraisal well, drilled on the Block 12 discovery offshore the Republic of Cyprus, has successfully encountered approximately 120 ft of net natural gas pay within the targeted Miocene-aged sand intervals. The Cyprus A-2 well, which is more than four mi northeast of the A-1 discovery location, was drilled to a total depth of 18,865 ft in 5,575 ft of water.
Production testing procedures were performed over a 39-ft section of the upper Miocene reservoir. The test, limited by surface equipment, yielded a maximum flow rate of 56 MMcfd of natural gas.
Performance modeling indicates development wells in the reservoir should have capacity to deliver up to 250 MMcfd. Evaluation of drilling data, wireline logs and reservoir performance information has resulted in an updated estimate of gross resources of the field ranging from 3.6 Tcf of natural gas to 6 Tcf, with a mean of approximately 5 Tcf. The Cyprus A structure represents the third largest field discovered to date within the deepwater Levant basin.
Noble Energy operates Block 12 offshore the Republic of Cyprus with a 70 percent working interest. Delek Drilling and Avner Oil Exploration each have 15 percent working interest.
Noble Energy plans to move the Ensco 5006 drilling rig to Tamar SW, offshore Israel, at the completion of operations offshore Cyprus. The Tamar SW well, testing an exploration prospect offsetting the main Tamar field, is expected to reach total depth by the end of 2013. Noble Energy operates Tamar SW with a 36 percent working interest.
