Fluid design for well stimulation applications
Patent
·
OSTI ID:5964121
A basic design concept of stimulating wells is to design the stimulation fluid to have a mobility that is equal to or less than that of the connate fluids within the subterranean formation. This design concept permits the stimulation fluid to push out ahead of it the connate fluids and possibly rewet the reservoir rock to the desired oil wetness or water wetness. Stimulation of a permeable, oil-bearing subterranean formation is effected by designing a micellar dispersion to have a mobility at least about 2 times the mobility of the combination of water and oil connate to the reservoir, then injecting from about 0.1 to about 10 bbl per vertical ft of oil-bearing formation of the micellar dispersion into the formation and injecting drive water to displace the micellar dispersion out into the formation.
