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

14 March 2017

Gazpromneft-Yamal, a subsidiary of Gazprom Neft, has successfully completed 20-stage hydraulic fracking operations at its Novoportovskoye field, using “non-ball and socket” (Mongoose) technology — a method first used in developing hydrocarbon reserves on the Yamal Peninsula and based on the use of rapid-shift sleeves, allowing the opening and closing of individual frac ports. Such a system allows either individual fissures to be closed during well operation in order to prevent the ingress of water, or the closure of all fissures simultaneously, allowing subsequent multistage fracking.

Multistage fracking operations at two wells at the Novoportovskoye field have been undertaken by specialists from Gazpromneft-Yamal, with the support of the Gazprom Neft Science and Research Centre. The initial daily flow rate from a single well is 188 tonnes of oil. The second well is due to be commissioned shortly.

Vadim Yakovlev, First Deputy CEO, Gazprom Neft, commented: "Using the latest technologies in well construction and operation is allowing Gazprom Neft to bring new hydrocarbon reserves into development, meaning we can improve efficiency throughout the entire business. The successful testing of new technology using non-ball and socket (Mongoose) technology on Jurassic deposits at the Novoportovskoye field is further confirmation of our company’s openness to innovation and a further landmark in the development of a strategically important asset for us.
