Essay

The thesis is devoted to the study of issues of increasing gas recovery of exhausted gas deposits by displacing residual gas from a porous medium with nitrogen and intensifying the operation of production wells. Improved technologies for increasing the final gas recovery and current gas production from exhausted gas deposits by displacing residual gas from the porous medium with nitrogen, choosing the number and size of perforation channels in the bottomhole zone depending on the permeability of the formation; a reasonably rational degree of reduction in the filtration resistance coefficients of the bottomhole zone of watered gas wells; improved methodology for calculating the parameters of gas-lift operation of waterlogged wells.
