Downhole Gas Separator
First Claim
1. A downhole gas separator for an artificial lift system, comprising:
- an outer casing joined to production tubing at one end and comprising a mount for a plug at an opposite end from the production tubing, wherein the outer casing comprises openings through the outer casing;
a dip tube extending through an interior of the outer casing, wherein the dip tube is fluidically coupled to the production tubing at one end, and is open to the outer casing at an opposite end, wherein the opposite end is proximate to the mount for the plug; and
the plug, disposed in the mount, wherein the plug comprises a latching device configured to allow the plug to be pulled through the production tubing to a surface.

Abstract
Systems and a method for efficient downhole separation of gas and liquids while providing well access are provided. An exemplary system provides a downhole gas separator for an artificial lift system. The downhole gas separator includes an outer casing joined to production tubing at one end and comprising a fitting for a plug at an opposite end from the production line. The outer casing comprises openings through the outer casing. A dip tube extends through the interior of the outer casing, wherein the dip tube is fluidically coupled to the production tubing at one end, and is open to the outer casing at an opposite end, wherein the opposite end is proximate to the fitting for the plug. The plug is disposed in the fitting, and comprises a retrieval bar configured to allow the plug to be pulled through the production tubing to the surface.
