Setting a hydraulic production packer: a comparative study on existing plugging methods in highly deviated wells and a proposed conceptual design

One of the challenges to complete a highly deviated well is to set hydraulically set production packers. A hydraulically set production packer is set by pressuring up the tubing string to create a differential pressure between the tubing string and annulus. The tubing string’s closed system can be a...
