Study of Gas Separation Conditions during the Commissioning of a Rod Pumping Unit

Abstract

This article presents the outcomes of an investigation on gas separation inside the intake of pumps used in wells using the rod pump technique. Experimental investigations indicate that the gas separation coefficient is affected by both the geometric configuration of the pump intake and variations in gas flow rate. An empirical formula was constructed from the analysis of experimental data to ascertain the separation coefficient at the pump input. The calculations conducted indicate that the suggested formula allows the determination of the separation coefficient with enough precision.
