Europe Based Energy Firms Make Discoveries in Trinidad, Norway
London-based Range Resources Limited and Norway’s Statoil Petroleum AS announced Wednesday that they had made oil and gas discoveries in Trinidad and Norway, respectively.
Multiple hydrocarbon bearing zones were identified on the MD 250 well in Trinidad by Range following initial log evaluations. These zones are scheduled to be tested to determine the well's producing potential.
Range will commence a production testing program by perforating and testing four sand intervals located in the lower zone of the well between 3,350 and 3,900 feet with an estimated net pay of over 40 feet. The relevant approvals have been submitted to the regulatory bodies in Trinidad. Once testing on the lower zone has been completed, the company plans to test further “promising” intervals of the well, located in the middle and upper zone between 1,350 and 2,700 feet, with an estimated net pay of over 100 feet, pending approvals from the regulatory bodies. The MD 250 well was drilled to a total depth of 4,100 feet, “significantly ahead” of the expected drilling schedule.
During last year, RRDSL completed the construction of a three-cellar drilling pad in Trinidad. Once production testing on the MD 250 well has been completed, the company will evaluate the possibility of drilling any follow-on wells from the drilling pad, dependent on the results from MD 250.
Statoil Petroleum AS, operator of production license 035/272, discovered petroleum in wildcat wells 30/11-11 S and 30/11-11 A offshore Norway.
The primary exploration target for wells 30/11-11 S and 30/11-11 A was to prove petroleum in Upper to Middle Jurassic reservoir rocks in two nearby fault blocks. The secondary exploration target was to prove petroleum in Middle Jurassic reservoir rocks.
Well 30/11-11 S encountered an 82 foot oil column in the upper part of the well’s Tarbert formation, of which 72 feet had moderate to good reservoir properties. Well 30/11-11 A found a corresponding reservoir in the Tarbert formation, which was aquiferous with traces of hydrocarbons. The well was classified as dry. A preliminary estimation of the size of the discovery in well 30/11-11 S is between 7 million and 17 million cubic feet of recoverable oil.
Wells 30/11-11 S and 30/11-11 A were drilled to respective vertical depths of 11,961 and 10,938 feet below the sea surface. The wells, which will now be permanently plugged and abandoned, are the twelfth and thirteenth exploration wells in production license 035.
