Method and apparatus for placing a sand control device in an oil / gas well

摘要

A method for setting a gravel pack in an oil well through tubing situation includes the steps of running a tool body into the well using an electric wireline. The tool body is precisely positioned relative to the surrounding casing, and radially extending members attached to the tool are used to center the tool body in the well bore. Sand control media such as a gravel pack is disposed in the well annulus circumferentially about the tool body using a dump bailer. The use of radially extending members allow the tool body to pass through restricted diameter openings such as in production tubing, fittings, nipples, pressure control device, packers, valves and the like.
