An integrated approach has been formed to justify the designs of planned gas wells, taking into account the accumulated experience in the formation of a strategy and technology for the development of the turonian stage. A decision matrix has been created for choosing the optimal well completion method depending on saturation (pure gas and water gas zones) and reservoir properties (in particular Kh). An express assessment has been developed for choosing a well completion method for poorly explored and undrilled zones.

Materials and methods
By forming and performing many calculations on sector hydrodynamic models depending on saturation (pure gas and water gas zones) and reservoir properties (in particular Kh), individual well designs, the number of stages of hydraulic fracturing and tonnage proppant are recommended for each of the typical zones of the productive formation
according to the created decision matrix.
