Abstract
A method for diversion in multistage fracturing, comprising the steps of identifying an isolation failure between stages in a wellbore due to a point of failure; pumping a diversion mixture into the wellbore; plugging the point of failure with the diversion mixture; pumping a spacer fluid through the wellbore; and pumping an acid stimulation fluid through the wellbore to a frac sleeve upstream of the point of failure.
Claims9
A method for diversion in multistage fracturing, comprising the steps of:
- identifying an isolation failure between stages in a wellbore due to a point of failure;
- pumping a diversion mixture through the wellbore, where the diversion mixture comprises water, date palm seeds and solid diverters, where the solid diverters comprise date palm seeds and rock salts;
- plugging the point of failure with the diversion mixture, where the solid diverters are solid at the point of failure;
- and
- pumping a spacer fluid through the wellbore.
(canceled)
A composition for diversion in isolation failure between stages, the composition comprising:
- date palm seeds;
- and
- rock salts,
- where the date palm seeds and rock salts are solid diverters at the point of isolation failure.
