Usinskoye field is located in Komi Republic. The Permian reservoir of the field has high-viscosity oil and is developed using thermal recovery methods.
Progress
Сommissioning of production wells, the optimization of cyclic steam injection technology, and efficient tapping of the reserves on the margins of the deposit contributed to stable production growth at the field.
High
profitability of oil production from the field's Permian deposit is explained
by the existing beneficial taxation of high viscosity crudes.
Various oil recovery technologies are used at the field such as drilling of directional production wells and construction of horizontal wells, including for the application of the steam-assisted gravity drainage (SAGD) technology.
The
introduction of day rate contracts helped achieve record commercial drilling
speeds, with an increase of over 30%. New small-diameter well designs
demonstrated good drilling efficiency and delivered cost savings of over 10%. A
full-scale rollout of this technology will yield significant capital
expenditures savings due to the high number of wells planned for drilling at
the field.
Oil recovery factor is also positively affected by the dispersed injection of steam in the areas of steam treatment, the operations of cyclic steam injection in certain production wells including combined treatment with chemical injection.
