ABSTRACT:
An oil well tool for installation in a production tubing string to provide valved gas communication between the interior of the tubing string and the annulus between the tubing string and casing for improving production from the well. The tool includes a thick walled tubular body for in-line threaded connection in a tubing string and includes valved passageways for the automatic transfer of gas from the annulus into the interior of the tubing string when the pressure in the annulus exceeds the pressure in the tubing string by a designed differential. The tool can be installed in the well in various arrangements for improving production of the well.
