A series of core experiments has made it possible to establish that for fractured samples, reservoir properties decrease sharply as their stress state (effective pressure) increases. With a further decrease (or complete removal) of the stress state, reservoir properties are not recovered in fractured reservoirs. These experiments have scientific and practical importance for the optimization of practices of production-well operation in the Tournesian–Famennian fractured reservoirs.
