Geochemical interaction formation and injected water with fractured carbonate reservoirs

Authors: S.N. Popov (Oil and Gas Research Institute of RAS, RF, Moscow)

Key words: formation, technical water of oilfields, water flooding, core samples, fractured reservoir.

This paper describe the results of laboratory experiments in which a core samples with fracture, previously saturated with formation water filtered by floodwater. The changes of permeability of the samples, salinity and chemical composition of water filtered during experiments under the influence of a constant effective stresses corresponding to reservoir conditions shown in this work.
