Oil Production Technologies
Effective oil production management appears impossible without regular introduction of new technologies. When developing an oilfield, the goal is not only to find a petroleum accumulation and engineer the reservoir but to find a way to produce as much petroleum as possible with minimum operating expenses.
Gazprom Neft Science and Technology Center specialists are working to reduce operating expenses by optimizing downhole equipment operating parameters, increasing its trouble-free operation intervals, and well service life between repairs.The STC provides expert support to oil lift to surface and complex operations at pumping wells, carries out audits of compliance with the corporate standards in Gazprom Neft’s subsidiaries and technical audits of contractors and equipment manufacturers, develops and implements regulatory and methodology documents and training programs for Gazprom Neft’s subsidiaries personnel.
Together with the subsidiaries’ teams, the STC is working to meet the objective set by Gazprom Neft’ Upstream Division: annual production of 100 million tons of oil equivalent by 2020. To this end, the tasks related to development and replication of new technologies aimed at improving efficiency of mature fields, involving hard-to-recover reserves, and disseminating the best practices to optimize production and reduce the cost of proven technologies are being solved. Technology projects are being implemented to create a controlled shut-off valve for well maintenance operations, ensure oil production from low-yield uneconomical wells, prevent formation of asphaltene-resin-paraffin sediments on casing walls, and many more.
With the STC support, about 200 pilot projects to test new equipment and technologies at Gazprom Neft fields are held annually. In addition, information systems Electronic Asset Development: Artificial Lift, Shakhmatka and Tekhrezhim, and Knowledge Dissemination System are being implemented at all of Gazprom Neft’s assets. Automatic collection and analysis of production performance indicators facilitate work planning and making decisions aimed at improving production efficiency.
