Patent number: 9476285Abstract: A downhole tool for use in a multilateral wellbore includes a guide member on one end that selectively projects into a designated wellbore, where the designated wellbore can be a motherbore or a lateral wellbore. Pistons are set radially in a body of the tool that selectively push against an end of the guide member to pivot it into a designated orientation to guide the tool into the designated wellbore. The pistons are hydraulically actuated when probes that are on sides of the tool body extend outward into contact with a lateral wellbore. The probes block hydraulic flow when retracted, but when deployed outward they allow fluid communication to push the pistons against the guide member.Type: GrantFiled: October 25, 2013Date of Patent: October 25, 2016Assignee: Saudi Arabian Oil CompanyInventor: Shaohua Zhou

Patent number: 9441468Abstract: Method and apparatus for a hydraulic jet pump housing system for selective positioning of a slidable, ported inner sleeve using wireline shifting tools in a downhole condition which allows flow between the annulus and tubing string through the ported outer sleeve housing and ported inner sleeve when in the open position. When the ported inner sleeve is in the closed position, the annulus and tubing string are isolated from each other. The open position permits normal functioning of a hydraulic jet pump when seated in a standing valve in the same manner as a conventional hydraulic jet pump cavity assembly. The hydraulic jet pump can be extracted and inner sleeve shifted closed without using a blanking tool so that annular fluids are prevented from flowing into the production formation through the tubing string when the standing valve is removed.Type: GrantFiled: October 24, 2013Date of Patent: September 13, 2016Inventor: Barry E Pryor
