TagraS-RS Achieves Successful Breakthrough: Hydraulic Fracturing at the Vostochno-Padinskaya Area Opens New Opportunities
In the dynamic world of the oil and gas industry, where each day brings new challenges and opportunities, production stimulation technologies play a critical role. They not only enable increased hydrocarbon production, but also make it possible to bring even the most complex and previously inaccessible reserves into commercial development.
A vivid example of the successful application of such advanced technologies was the recent hydraulic fracturing operation at the Vostochno-Padinskaya area, carried out by Frac Fleet No. 10 of the Hydraulic Fracturing Division of TagraS-RS.
The success of the project at the Vostochno-Padinskaya area, specifically at Parametric Well No. 3-VP, where production was stimulated within the Achimov formation intervals, became possible through the application of a comprehensive scientific and technical approach.
As experience has shown, such detailed and multidisciplinary analysis is essential for achieving efficiency when working with low-permeability formations, including the Achimov reservoirs. These geological formations, created in deepwater marine environments, are characterized by a complex structure consisting of alternating sandstone-siltstone and clay layers. Their reservoir properties, combining high porosity with low permeability, present a major challenge for conventional production methods.
The implemented project was the result of meticulous preparation and coordinated teamwork among specialists. The operation was supervised by leading hydraulic fracturing engineers of TagraS-RS — Airat Gazetdinov and Ildar Khanov.
During the preparation phase, more than 10 different fracturing designs were developed, featuring varying proppant volumes and pumping technologies. Following detailed analysis and calculations performed with the participation of leading experts from Gazprom PJSC, Gazprom VNIIGAZ, Gazpromnedra, and the Hydraulic Fracturing Division of TagraS-RS, the team selected a hydraulic fracturing technology involving the injection of a combined buffer stage. During the main fracturing operation, 69.1 tonnes of proppant were successfully pumped into the formation.
“We would like to thank the entire crew of Frac Fleet No. 10, led by Supervisor Ilya Demakhin and Engineer Aydar Ayupov, as well as Project Manager Irek Idiyatov and leading engineers Airat Gazetdinov and Ildar Khanov from the Hydraulic Fracturing Division, for their dedication and high level of professionalism, which made the successful execution of this operation possible,” said Gulnaz Valiullina, Hydraulic Fracturing Development Project Manager at TagraS-RS.
