One of the key strategic objectives of Rosneft Oil Company is the creation of tools to increase the company's efficiency at all stages of the production chain, including oil and gas production at the lowest cost. A significant factor affecting cost reduction is improving the efficiency of well production. The main focus of work to improve the efficiency of well operation is the search for the most efficient ways to operate low-yield wells (flow rate less than 20 m3/day), the number of which in Bashneft Company is more than 70% and is characterized by the highest unit costs.

In order to achieve the strategic goal, the following task was formulated - the abandonment of drives like sucker-rod pumps. To solve this task, significant work was carried out with the constant interaction of Bashneft and Rosneft services, which made it possible to implement and test a number of technical and technological solutions based on the use of plunger pump installations with a linear drive. The resulting solution characterized itself, during the pilot field tests, as a technology with high rates of service life and increased energy efficiency in relation to the known analogues. A number of technical and technological problems related to the introduction of plunger pump installations with a linear drive and its modifications were solved, and proven basic principles for ensuring trouble-free operation for this type of facilities were formed. This solution made it possible to use the advantages of the rodless method of operation using the volumetric type of pump, which has the greatest efficiency and high resource.
