Pilot production has begun at Gazprom Neft’s Tympuchikanskoye field, located in Eastern Siberia. The project includes operation and testing of well 96P.
The oil produced at the field is trucked to points of sale. The region’s geographical and climatic condition will allow only seasonal shipment of crude, from December through April, during the next few years.
Last year, five previously drilled wells were reactivated and retested at Tympuchikanskoye field. The flow rates reached 110 cubic meters of oil per day. 3D seismics were also shot covering a 300 square kilometer area. There are plans to continue seismic surveys in 2013, including further reactivation and retesting of the old well stock, as well as drilling three exploratory wells and one prospecting and appraisal well. Approximately 450 square kilometers will be covered by the seismics. Most of the area will be studied using the innovative technology UniQ, which is being applied here for the first time in Russia.
Tympuchikanskoye is one of the fields of the Chona project that Gazprom Neft is implementing in Eastern Siberia. Vakunaiskoye and Ignyalinskoye fields, which are adjacent to Tympuchikanskoye field, are also included in this project. All of the fields are located on the border of Irkutsk Oblast and the Sakha Republic (Yakutia). In mid 2012, Gazprom Neft executed an agreement with the Japanese firm JOGMEC for joint geological study of the Ignyalinsky site. The company is conducting geological exploration at the two other fields independently. The license for the Tympuchikansky site was obtained in 2005, and that license belongs to LLC Gazpromneft Angara. The Chona group fields are located within 80 kilometers of the Eastern Siberia-Pacific Ocean (ESPO) pipeline.
In late 2011, as the result of geological exploration and reinterpretation of extant geological data, Gazprom Neft increased its reserves estimate in the Chona group to over 125 million tons of oil and 225 billion cubic meters of gas, all belonging to categories C1 and C2.
