Ball sealer diversion of matrix rate treatments of a well
Patent
·
OSTI ID:5723654
A method for sequential treatment of formation strats when treating fluid is pumped into a well at a matrix rate by temporarily closing perforations in the well casing. The perforations are closed by ball sealers injected into the wall during the treatment. The ball sealers are sized to plug the perforations and have a density less than the density of the treating fluid. The treating fluid is injected at a rate which transports the ball sealers to the perforation but which is sufficiently low to prevent formation fracture. 17 claims.
