Oil and gas innovation must be environmentally friendly
Tashkent, Uzbekistan (UzDaily.com) -- Innovative solutions in the field of oil and gas production can increase its efficiency by 4-5 times, without harming the environmental component of the sphere.
In particular, the ERIELL Group is working on the use of the hydraulic fracturing method (hydraulic fracturing), and at the same time a set of environmental measures is being taken together with leading global partners.
The company has developed and adopted a management regulation (standard) that defines the procedure for hydraulic fracturing and defines special requirements in the field of environmental protection, monitoring, and subsoil protection.
During hydraulic fracturing, there is the possibility of penetration of the fracturing fluid into the soil and the underground aquatic environment, which is taken into account by the “ERIELL Group”.
In this context, the company has prepared a special program that is being implemented with the American partners Halliburton International GmbH (hydraulic fracturing design, supervising and upper completion equipment) and Weatherford International Ltd. (lower completion equipment), as well as the Russian LLC Gasstream (technical operational work).
Thanks to such cooperation, for the first time in Uzbekistan, multi-stage hydraulic fracturing (MHF) will be carried out in individual wells with a horizontal well 1000 meters long and low permeability formations, each of which will carry out up to 10 hydraulic fracturing stages.
In recent years, multi-stage hydraulic fracturing (MHF) has become the main trend in the world when operating low-permeability hydrocarbon reservoirs in oil and gas fields.
ERIELL Group specialists, having studied the oil and gas saturation of all intervals of the fields being developed, and also taking into account their many years of experience in conducting hydraulic fracturing in Russia, Iraq, Bangladesh and other countries, came to the unambiguous conclusion that to increase the permeability of the bottom-hole zone of the reservoir due to formation of cracks or expansion and deepening in it of natural cracks, it is necessary to apply this method.
The shift in emphasis in favor of multi-stage hydraulic fracturing was associated with the high efficiency of such operations: during a one-stage hydraulic fracturing, the well flow rate in the first year after the operation can grow by 0.8-2.4 times (depending on the geological structure of oil and gas reservoirs, field development schemes etc.). When performing multi-stage hydraulic fracturing, the flow rate in the first year after the operation may increase by 5-6 times.
