Gazprom Neft increases its estimate of recoverable reserves at its Zhagrin field

Following analysis by the Federal Subsoil Resources Management Agency, recoverable reserves at Gazprom Neft’s Alexander Zhagrin field in the Khanty-Mansi Autonomous Okrug have been increased to 31 million tonnes of oil equivalent (mtoe), confirming the geological prognosis made by specialists on the oil-bearing area of the block, clarifying the previous provisional calculation and, under current oilfield classifications, placing the field, named in honour or Alexander Zhagrin, in the “significant” category.

The field was discovered in late 2017 at a promising licence block in the Kondinsky district of the Khanty-Mansi Autonomous Okrug-Yugra. In January 2018 this new Gazprom Neft asset was named in honour of Alexander Zhagrin, the former head of the company’s Oil and Gas Production Directorate.

Geological prospecting works at the licence block in the Kondinsky district of the Khanty-Mansiysk Autonomous Okrug-Yugra are being undertaken by Gazprom Neft subsidiary Gazpromneft-Khantos, with seismic works planned and undertaken, a geological model of the reservoir created, and a 3,000-metre prospecting and appraisal well drilled — completely autonomously, and in the shortest possible time. In testing the main exploration target the first prospecting and appraisal well delivered an inflow of dry crude with design flow rate of 50 cubic metres per day.
