... prediction model. This paper gathers, interconnects, and examines several available research works through data analytics. The results provide a fundamental source and a valuable guideline for downhole liquid-gas separation, particularly in artificial lift applications. drillstem/well testing...

... Abstract To deal with gas and sand problems in their conversion and rod pump wells an operator company in south Texas started introducing a combined technology of two-stages filtration with a modified poor boy gas separator obtaining excellent results. This paper explains the technology used...

... of the difficulty of separating downhole oil that is to be lifted to the surface from large volumes of gas especially in rod pumped wells. Many downhole gas separators are inefficient, and the percentage of liquid in the pump is actually less than the percentage of liquid in the fluids in the casing annulus...

... conditions as well as Russian State University of Oil and Gas (RSUOG) correlations for the performance of rotary gas separators. The first two set of correlations were developed using data acquired with TUALP experimental facilities but have not been tested against field data. The correlations developed...

... of having a pump capacity that exceeds the production rate of the well or having poor gas separation at the pump intake with a portion of the pump displacement being lost to gas interference. More efficient operations and lower cost will result, if these wells are operated with the pump filled with liquid...

... ABSTRACT A novel gas separator design has been developed and successfully tested in several beam pumped wells which were subject to severe gas interference. This paper presents a detailed description of various designs to cover various ranges of fluid production for the most common sizes...

... performance [1] to determine projected production. Corrections for free gas problems use a combination of Vogel procedures with Lea and Bearden's recommendations for gas separators [2] . For stable well conditions, the pump is designed to operate on the right of the curve. For dynamic well conditions...
