TNG-Group and VNIGNI will Choose the Optimal Hydraulic Fracturing for Bazhen in Ugra
In 2023–2024, the VNIGNI Institute will continue to study the Bazhenov formation of the Zaozernaya area together with the geophysical company TNG-Group (part of Tagras-Holding). Other divisions of the TAGRAS oil service holding are involved in work in Khanty-Mansi Autonomous Okrug-Yugra. The Devon News Agency learned about this from a message from the press service of the All-Russian Research Geological Petroleum Institute.
Among the tasks are the study of the filtration properties of anomalously heterogeneous reservoirs of the Bazhenov formation, the selection of inflow stimulation methods for a promising interval. It is also necessary to perform a laboratory study of the properties of formation fluids.
Selecting the optimal hydraulic fracturing (fracturing) mode for Bazhen, controlled by microseismic monitoring, will maximize hydrocarbon production.
It is also planned to comprehensively study the properties of reservoirs and fluids of the anomalous Bazhenov formation. After this, methods and technologies for influx intensification will be selected. The research will be monitored using surface geophysical methods. This is a new type of work for VNIGNI.
In October 2023, reconnaissance was carried out at the prepared work site. The work was attended by specialists in well overhaul (workover), hydraulic fracturing, field geophysics and microseismic monitoring.
They inspected the wellhead equipment, outlined the area where the hydraulic fracturing fleet, workover crew equipment, and geophysical equipment would be located. The location of the residential town has also been selected. Logistics and technical solutions were worked out separately.
In 2021, VNIGNI built a parametric well with a depth of 3 km in the Zaozernaya area. This is the first well independently drilled by the All-Russian Research Geological Petroleum Institute.
