Gas. Its production under the terms of a production sharing agreement

Gas is associated with low-porosity and low-permeability reservoirs that lie at great depths (5-8 kilometers) mainly in parts of the depression.

In addition to low filtration and capacity properties, gas characterized, as a rule, by low well productivity, which requires constant drilling in large quantities, the need to use stimulation (fracking) and horizontal drilling, short well life and a rapid drop in their flow rate (by half in the first year).

Search, exploration and production of gas accumulations have its own specific features, which is why it is distinguished into a separate type.

To assess the possibility of producing basin-type gas, it is necessary to:

1) conduct a modern interpretation of available geological and geophysical materials and perform a scientific justification of the most promising areas of possible accumulations of gas;

2) perform a complex of geophysical studies, including seismic 3D modeling, identify traps and locations for parametric wells.

3) to drill parametric wells with full core sampling in the promising part of the section, as well as modern comprehensive petrophysical core studies to create interpretative models.

4) conduct a geological and economic assessment of priority oil and gas prospecting objects and prepare them for use;

5) implement the necessary technical regulation and economic incentives at the national level to attract investors to search for such resources.

Full implementation of these tasks will allow us to increase the natural gas resource base.
