JETTING TOOL FOR BOOSTING PRESSURES AT TARGET WELLBORE LOCATIONS

摘要

Well systems including a wellbore lined with a wellbore lining and a pressure booster extendable within the wellbore on a conveyance whereby an annulus is defined between the conveyance and the wellbore lining. The pressure booster includes a body having a first end coupled to the conveyance, a jetting chamber defined within the body, one or more flow ports defined in the body and providing fluid communication between the jetting chamber and the annulus, and a jet nozzle in fluid communication with the conveyance. The pressure booster receives a first fluid through the conveyance and a second fluid from the annulus and mixes the first and second fluids to discharge a fracturing fluid below the pressure booster at a pressure greater than a pressure within the annulus above the pressure booster.
