Key words: low-permeability formation, reservoir, filtrate, bottomhole area, water-oil-gas saturation.
ПThe paper describes methods and findings of experimental studies of mud filtrate invasion into a low-permeability reservoir. It is shown that the weight method of investigation of mud filtrate invasion into a low-permeability reservoir allows to control the rate of capillary imbibition in gas reservoirs.
