CLAY SWELLING AND NON-TARGET CONSUMPTION OF FRACTURING FLUID ADDITIVES: DIAGNOSTICS AND FIELD EXPERIENCE USING FORMATION WATER AT THE VOSTOCHNY MOLDABEK FIELD
The effectiveness of hydraulic fracturing (HF) largely depends on how well fracture conductivity is preserved after the fracturing fluid interacts with the reservoir rock. This paper systematizes the permeability-damage mechanisms related to the water sensitivity of clay minerals interlayer smectite swelling, osmotic e...
