Problems of deep drilling in abnormally pressured zones of the Kara Sea continental shelf
There are discussed results of drilling operations in shelf hydrocarbon areas of the Far North of Tyumen Region (Kharassavieskaya, Bovanenkovskaya and Krusenshternskaya ones) and on the Bely Island. The author describes equipment and technologies used, problems arising in the process of operations and possible ways of solving them. Application of the results discussed in the report seems rather attractive in connection with possible realization of joint projects on development of the mentioned areas. Thus, Amoco Eurasia plans to participate in development of Bovanenkovskoye and Novoportovskoye fields. Well planning for Amoco has been done of specialists of ZapSibBurNIPI. Experience of Russian drilling companies in the Yamal area (Far North of Tyumen Region) has proved that well planning for shelf areas requires special attention as drilling-in both overpressured zones (Bovanenkovskoye field) and underpressured ones (Novoportovskoye field) is done actually in balance. Investigated are reasons for such drilling problems as kicks and lost circulation. Taking them into consideration will help to decrease considerably the cost of well drilling in shelf areas.
