Specialists from RN-Purneftegaz, a subsidiary of Rosneft, have implemented modern technology that improves well productivity and extends production period. The development is based on the use of directed gas-dynamic effects on the bottomhole formation zone. As a result of pilot tests, the volume of additional oil production at four inclined injection wells amounted to 1,500 tons since the start of the first well in early February 2019.
The introduction of the best practice and new technologies is one of the key areas of the Rosneft-2022 Strategy. The Company pays special attention to innovative development, recognising technology leadership as a key competitive factor on the oil market.
Operating principal of the new technology is to create gas pulses of varying intensity in the reservoir with the use of a special generator, which is lowered into the well. Pulse ontime is from 0.3 to 1.5 seconds. The pulse cleans the bottomhole formation zone, therefore improving the permeability of the rock and increasing well flow rate.
The entity plans to test the application of innovative technology in wells with horizontal completion to rebound their productivity. In the next three years, the share of all promising technologies will be up to 25% of the total number of operations in the bottomhole formation zone treatment at RN-Purneftegaz.
