Abstract

Concerning ESP (or other artificial lift systems) for producing gas wells. This invention is for a 'liquid trap and gas bypass' system that reduces liquid loading, prevents gas-locking of the down-hole pump, and/or simply prevents loss of liquid volume to the down-hole pump (or other artificial lift method). The function is simple: gas pushes (or carries) liquid to the top of the trap and liquid travels back down the well-bore through an 'extension tube' while gas/liquid is flowing upward in the casing annular space. This system is simple and offers a greater gas handling capability for almost any gas well with utilizing a down-hole pump system. Applicable for any high flow or low flow gas wells (conventional or unconventional), gas well dewatering applications (vertical wells, horizontal wells, slant wells).

This system is simple and offers a greater gas handling capability for almost any gas well with utilizing a down-hole pump system. Applicable for any high flow or low flow gas wells (conventional or unconventional), gas well dewatering applications (vertical wells, horizontal wells, slant wells). The Problem: ‘Water gets in the way of gas flow’. 1. In gas wells which produce liquid (or gas well dewatering applications), it is desired to draw the well down to the lowest reservoir pressure as possible in order to maximize gas (and oil) production. The higher the liquid is in the well then the less production obtained. 2. In gas wells (or oil wells) that have extended reach laterals or horizontal sections, it is likely that gas may enter the wellbore in large gas slugs. These large gas slugs can push the liqui...
