FIELD: equipment and methods of product recovery from well; particularly, filtration of product recovered from gas and gas-condensate wells. SUBSTANCE: method includes lowering of well screen, washing-up of gravel filter into formation and into annular space between pipes, inducing gas inflow to well through gravel filter and well screen. Gas inflow to well is induced through screen filter-sleeve installed inside well screen through which gas is filtered from formation water. Rising formation pressure, in this case, is released through safety valve. Safety valve is located above well screen. EFFECT: efficient filtering of recovered product to remove formation water. 2 dwg
