Russian Drilling Programs Poised to Best 2012 Highs

By Lada Ponomareva, March 5, 2013

an extensive analysis of shale oil drilling results this spring and decide on future drilling at the Bazhenov-Abalak formation at Krasnoleninskoye field based on results of the analysis. "Study of the Bazhenov-Abalak structure is designed to improve efficiency of the development of shale oil reserves - hydrocarbons located in the Bazhenov, Abalak, and Frolov formations in West Siberia that have extremely low permeability, but high oil saturation. These reserves are under explored," Gazprom Neft stated in a press release.

Gazprom Neft expects to increase capital investment from $5 billion in 2012, to $6 billion in 2013 and $7 billion in 2014. The company plans to invest in new field development and modernization of processing facilities. Between 2013-15, Gazprom Neft plans to spend approximately $23 billion on total investment, 44 percent of which will be used for the development of new onshore and offshore shelf projects, for the development of reserves in traditional fields, and for exploratory operations in Eastern Siberia.
Tatneft provided the most detailed report on well bore operations last year (for summarized results see Table 2). The company continued to increase drilling acreage (both development and exploratory), lateral and horizontal wells, and enhanced oil recovery methods (hydraulic fracturing, chemical treatment, etc.). Total incremental oil production resulting from these operations amounted to approximately 12 million tons.
