Marathon Makes Discovery Offshore Norway

Marathon Oil has made an oil discovery on the company-operated Kneler 25/4-7 well. The discovery is located in production Deepsea Bergern license (PL) 203, which is approximately 140 miles from Stavanger, Norway in 390 feet of water. The well was drilled by Odfjell Drilling's semisub, Deepsea Bergen.

Commenting on the discovery, Philip Behrman, Marathon senior vice president of Worldwide Exploration, said, "We are pleased to have success on our first well as an operator in Norway. This discovery is the first part of a three well program designed to evaluate the West Heimdal area. The success realized with the Kneler prospect demonstrates the potential of this Marathon core area."

The Kneler well was drilled into the prolific Heimdal formation, located about 7.5 miles west of the Heimdal platform and drilled to a total depth of 7,425 feet below sea level. The well encountered a 155 foot gross oil column. Extensive down-hole samples, core and wireline logs were collected and are currently being analyzed. The next exploration well to be drilled is on the nearby Boa prospect in PL088BS, which will drill into the same formation.

The PL203 group includes Marathon as operator with a 65-percent working interest, ConocoPhillips with a 20-percent interest and DNO with the remaining 15-percent.
