Unique wells with two holes were drilled in Kholmistoye field

The company «Gazprom Neft – Noyabrsk-neftegaz» drilled two unique wells with two holes in Kholmistoye field.

With consideration of horizontal parts the length of one of them makes 4800 meters, another – 4500 meters. Both wells were built on the following technology: a well is divided in two horizons on the depth of a deposit, and a bottomhole pump is situated higher than branching of holes. Usually builders strengthen only one of holes of a well, therefore, time of work of the second one is restricted with several months – a stratum is washed out, rocks falls in. This time with help of new Russian equipment the specialists conducted casing of both holes. The new technology will allow receiving long-term oil inflow. As it is informed in the press-service of the company «Gazprom Neft – Noyabrsk-neftegaz», both wells already exceeded project capacity, which makes 85 tons of oil per day. The first gives 98 tons, the second – 88 tons.
