Gazpromneft-Noyabrskneftegaz, one of many main producing amenities of the Gazprom Neft Group, has recognized two new promising clusters, with reserves in place estimated at 80 million tonnes of oil equal (mtoe), throughout geological prospecting works on the Vorgensky license block (Yamalo-Nenets Autonomous Okrug)
Company specialists shall be enterprise 3D seismic works, along with exploratory and appraisal drilling, as a way to make clear the blocks’ full useful resource potential by 2025.
Geochemical prospecting had beforehand been undertaken over a 7,000 km space on the Vorgensky block, with the purpose of evaluating fluid sorts (oil, gasoline condensate and gasoline) — the outcomes obtained, along with 2D-seismic information, having made it doable to establish a 1,300-km space with potential for extra detailed investigations.
“The Vorgensky block is presently the biggest in Noyabrskneftegaz’s asset portfolio. Outlining oil-bearing strata will result in better success in exploratory and appraisal drilling, and speed-up the following improvement of this space, which shall be a significant factor not simply within the additional improvement of our enterprise, however for oil manufacturing in Yamal, as a complete.” mentioned Gazpromneft Noyabrsk neftegas CEO.
Covering an space of 11,700 sq. kilometres, the Vorgensky license block is situated within the Krasnoselkupsky District of the Yamalo-Nenets Autonomous Okrug, 320 km east of Noyabrsk. It varieties a part of Noyabrskneftegaz’s Otdalennaya group of fields, and adjoins the Vorgensky discipline, underneath improvement since 2010.
Surface geochemical surveying is a technique for evaluating floor concentrations of hydrocarbons, based mostly on the assumption that hydrocarbon molecules situated at depths of two to a few kilometres can migrate and kind geochemical fields. Detecting these molecules makes it doable to establish the boundaries (borders) of oil-bearing areas, and to evaluate the part composition (fluid content material) of the hydrocarbons inside such deposits.
