Gazpromneft-Khantos Improves Efficiency in Oil Production in the Khanty-Mansi Autonomous Okrug

Gazprom Neft subsidiary Gazpromneft-Khantos has, for the first time, undertaken high-tech fracking using a polyacrylamide-based mixture — this new approach increasing individual well production by up to 20 percent.

Polymer-based fracking was used at the Yuzhno-Priobskoye field in the Khanty-Mansi Autonomous Okrug, with polyacrylamide** being used as an alternative to the guar-based fluid traditionally used.*** Injected into the well, the mixture prevents the fissures formed in the strata under fracking from closing up.

Using a synthetic polymer makes it possible to create a predictable fissure system, increasing depth by 15 percent as well as increasing reservoir coverage and oil inflow. Using polyacrylamide does not incur any additional costs, while the mixture’s unique properties, moreover, increase production of liquid hydrocarbons under fracking by up to 20 percent per well.

Gazpromneft-Khantos plans to increase its use of polyacrylamide in fracking, in the future, and to roll-out its successful experience in using it at its remaining fields in the Khanty-Mansi Autonomous Okrug.

«The company faces a serious challenge in making sure non-traditional, hard-to-recover reserves are developed profitably. The main driver behind efficient oil production at low-permeability reservoirs is high-tech fracking — something we are constantly improving.»
