Seven Seas Initiates Pressure Build Up Test in Guaduas Oil Field; Testing Of El Segundo 6-E Redrill Continues, Testing of Tres Pasos 3-E Well Postponed HOUSTON, Nov. 30 /PRNewswire/ -- Seven Seas Petroleum Inc. (Amex: SEV - news; TSE: SVS.U - news) announced today that it has shut in the Guaduas Oil Field for a pressure build up test that will be used by its independent reservoir engineers to estimate year-end 2000 oil and gas reserves. The Company and its partners agreed to conduct a pressure build up test following the Guaduas Oil Field's production of over 400,000 barrels of oil since August 9, 2000. The total amount of oil produced by the Guaduas Oil Field to date is approximately 1.2 million barrels. The Company expects to resume Trucking Production in early January 2001. ``This pressure build up test will further enhance our understanding of the Guaduas Oil Field and aid us in refining the development drilling program we plan to initiate in 2001,'' stated Robert A. Hefner III, Chairman and Chief Executive Officer of Seven Seas. The Company also announced that testing of the El Segundo 6-E redrill has resumed and will continue for approximately one more week, as permitted by the Colombian Ministry of Mines and Energy. The El Segundo 6-E redrill will then be shut in and future operations will be determined following the evaluation of the production and pressure data from the well. Additionally, operations to test the Cimarrona formation of the Tres Pasos 3-E well have been postponed until after the Guaduas Oil Field pressure build up test. The Tres Pasos 3-E well was originally drilled in September 1998. The Cimarrona is the productive formation of the Guaduas Oil Field. Seven Seas Petroleum Inc. is an independent oil and gas exploration and production company operating in Colombia, South America. The Company's primary emphasis is on further exploration, development and production of the Guaduas oil field, located in Colombia's prolific Magdalena Basin.
