Gazprom Neft undertakes 20-stage fracking operations first ever in the Yamal Peninsula

* Hydraulic fracking is a means of increasing oil production. It involves the high-pressure injection of a mixture of fluids and a special proppant agent (proppant) into strata. The process of injecting the mixture creates highly conductive channels (“hydraulic fractures”) connecting the bore hole and the strata, resulting in oil inflow. Under multi-stage fracking, multiple fracking operations can be undertaken from a single horizontal well, allowing a manifold increase in the catchment area covered from that well.

The Novoportovskoye field is one of the most significant oil and gas condensate fields currently under development in the Yamalo-Nenets Autonomous Okrug. Recoverable C1 and C2 reserves are estimated at more than 250 million tonnes of crude and condensate, as well as more than 320 billion cubic metres of gas (including Palaeozoic deposits). The field is located in the south—east of the Yamal Peninsula, some 250 kilometres north of Nadym, and 30 kilometres from the coast of the Gulf of Ob.

Oil from the field is currently transported to the coast through a pressure-pipeline running to more than 100 kilometres in length. Infrastructure established at the field and on the shores of the Gulf of Ob allows the transhipment of up to 8.5 million tonnes of oil per year. The year-round shipment of crude is ensured through the Arctic Gates crude-oil loading terminal — the only such terminal in the world located in a freshwater zone of the Arctic Circle.

The characteristics of this new Yamal oil (named “Novy Port” crude) classify it as “medium-gravity crude”. Its low sulphur content (of around 0.1 percent) is lower than that of Russian Urals-blend crude.
