Abstract:

Purpose. Development of a new methodology for calculating gas reserves for gas wells of any productivity.

Methodology. The calculation method was developed using the theoretical provisions of gas dynamics. It is based on the actual data from the study on gas wells in one developed mode.

Findings. For the first time, a methodology for calculating gas reserves was proposed during the development of one study mode. In parallel with the calculation of gas reserves, the possibility of analytical calculation of a significant number of gas-hydrodynamic parameters opens up.

Originality. The developed methods for calculating the value of the initial gas reserves and gas-hydrodynamic parameters of the studied gas objects have no analogs in domestic and world practice. The first of the methods is distinguished by the simplicity of calculation and the availability of the initial data for its use. The second is based on the differential, differential-integral, and integral methods to improve the accuracy of the calculated results.

Practical value. The new methods for calculating gas reserves will make it possible to quickly assess hydrocarbon raw materials in the investigated object. The availability, minimization, and accuracy of the initial data for calculating gas reserves are undoubtedly signs of the optimality of the method. The simplicity of the calculation makes it possible to widely use the technique. The use of a new methodology for interpreting the results of gas well research in one mode will make it possible to depart from the traditional research method. Due to this, the number of research modes is reduced by several times. It also means a reduction in emissions to the atmosphere if the well is not operated with backpressure at the wellhead. A significant reduction in the cost of the research process due to the reduction in research time is also a factor in significant savings in research funds.

Keywords: well survey, method for calculating gas reserves, gas-saturated formations, gas-hydrodynamic parameters
