Based on geological and technological factors, it is necessary to take into
account the gas extraction coefficient when calculating reserves for gas and gas condensate
fields. The increase in gas reserves should be drained only by recoverable reserves, which most
realistically reflect the availability of resources for the oil and gas industry. The purpose of the
work. Analysis of the dynamics of the development of the Surgil, East deposits. Berdakh-Uchsay,
Urga with the whole determination of the final volume of drained gas reserves, the assessment
of the gas recovery coefficient and the development of a recommendation on the methodology
for determining the gas recovery coefficient at the fields, with surocheins to the Jurassic
erogenous deposits. The gas extraction coefficient estimated according to the data of the
Ustyurt field development now is clearly underestimated in comparison with the well-known
ones according to literary sources for sand-clay reservoirs.
Therefore, it becomes an urgent task to estimate the maximum possible volume of gas
extraction and estimate the gas recovery coefficient. The magnitude of the gas output of productive erogenous reservoirs developed in the natural mode significantly depends on: the
reliability of determining the initial hydrocarbon reserves, the efficiency of the selected
development system; lithological features of the reservoir structure; the uniformity of the
structure of the reservoir pore space in terms of deposit area and section; the consistency of
reservoir layers in terms of power and the uniformity of their interlayers in terms of FEZ.
According to these factors, the acamu changes the final gas output of the deposits.
The criterion in this case was the data of the reserves assessment using the pressure drop
method, showing how much of the initial reserves is involved in drainage and how it changes
during operation. The results of the work and conclusions. The extracted gas coefficient, being a
purely economic concept, will be determined either by the results of hydrodynamic studies or
empirically by the results of the development of deposits similar to the one being studied. A
certain amount of gas due to the heterogeneity of the filtration and reservoir properties of the
reservoirs remains in their small pores or depends on technological factors associated with a
drop in reservoir pressure to a critical level-further development of the deposit becomes
unprofitable. Thus, the coefficient of extraction of gas deposits in various conditions associated
with either a geological or technological factor becomes lower than one
