As horizontal wells deplete, there becomes a greater need to reduce bottom hole flowing pressure. Methods such as gas lift and jet pumping can be run into the curve but are limited in ability to drawdown bottom hole pressure. On the other hand, rod pumps are most commonly used, but have difficulty running past a certain degree of wellbore deviation and suffer from gas locking and interference due to the slug flow. A new gas anchor system has been developed to deploy into the horizontal section of the wellbore and has shown efficient in gas liquid separation. The tool is simple and easily installed in wellbores.
