OREANDA-NEWS. April 16, 2010. The number of subeconomic wells at fields operated by Sorochinskneft (part of Orenburgneft, a subsidiary of TNK-BP) was cut by 25% during March, reported the press-centre of TNK-BP.

According to Arkadiy Popov, head of Sorochinskneft’s field development section, production in most of the wells is subeconomic because of the high water-cut.

“After assessing the commerciality of the entire operating well stock together with the economics department, we compile a list of subeconomic wells and decide whether to perform well interventions or to shut in wells for subsequent suspension or abandonment”, says Popov. “During March 2010 the number of subeconomic wells was cut by 25%, or by 13 wells, 10 of them thanks to well interventions.”

It should be noted that Sorochinskneft monitors the performance of each well that is currently subeconomic on a monthly basis.

Popov noted that the monitoring programme will help to achieve annual savings across Sorochinskneft of around 6 million rubles.
