Gazprom Nedra Continues Geological Exploration at the Chayandinskoe Field

Gazprom Nedra LLC continues work on additional exploration of the Chayandinskoe Oil and Gas Condensate field (OGCF) in the Republic of Sakha (Yakutia) — the primary resource base for the main gas pipeline Power of Siberia. During tests of Borehole No. 321–105, drilled to a depth of 1,725 meters, an industrial flow of gas was obtained. In addition, the borehole also produced oil inflows from the Khamakinskiy Productive Horizon. The test results will be processed and will make it possible to refine the geological and geophysical model of the structure of the deposits of the Khamakinskiy Horizon, determine the boundaries of the distribution of reservoirs, and also increase the reserves of the field.
