... Abstract Pumping artificial lift techniques, such as rod pumps and ESPs, are applied for gassy wells more than ever before. This has made the downhole separators a critical part of most such installations. There are multiple categories of downhole separators, with various techniques developed...

... 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...

... equipment. Although sand flow is greatly reduced following an initial period of flow (30 to 60 days), the slugging nature of horizontal wells provides a significant risk for unexpected large quantities of sand to damage permanent separation equipment, surface piping and valves. Installing sand probes has...

... Abstract This paper provides a simplified approach to sizing 2 and 3 phase separators in low GOR (<2000 scf/STB) applications. The paper will provide the facility engineer with a straight forward method for beginning the sizing of the separation system. Once the first pass sizing has been...

... 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...

... Abstract The premise that high annular velocities on rod pumped gas wells can cause liquid holdup in the casing is presented. A case is then made (using conventional vertical separator sizing equations) that the annular cross-sectional area is inadequate to allow gas-liquid separation to occur...

... Abstract This paper presents the results of field evaluation by Rosneft of correlations developed by the Tulsa University Artificial Lift Projects (TUALP) to predict the performance of the natural separation process and of Electrical Submersible Pumps (ESP) operating under multiphase flow...

... Abstract This paper presents the optimization study of a rotary gas separator (RGS) in ESP systems by improving the performance of the inducer part of the RGS. Using two-phase flow inducer model, sensitivity studies were performed to three inducer blade geometrical variables, i.e., tip diameter...

Minimum-net-positive-suction-head considerations limit artificial lift options. The dew point at low pressures allows large volumes of water to move as vapor—rendering mechanical separation...
