... Abstract Determining artificial lift options in mid to late-life unconventional wells is paramount to the economic success of hydrocarbon recovery. This paper will compare two different artificial lift methodologies (HPGL & ESP) in wells in the same formations. Key comparisons of economics...

... Abstract Making high rates reliably with low costs from unconventional wells remains challenging. In 2017, SPE 187443 asked whether there was an opportunity to do this with high pressure gas lift (HPGL). In 2019, HPGL showed rates comparable to ESP's (SPE 195180). This paper presents results...

...Hipot Test The objective of this test is to verify the quality of the insulation in power cables, motor lead extensions (MLEs) with their connectors, motor windings, and connectors (in the case of MoBo or skid-mounted ESP, a Hipot test for their connectors is also mandatory). The test involves...

... the horizontal lateral and the vertical production tubing are the source of slugging, which creates fluctuations of fluid density in the wellbore both upstream and downstream of the ESP. Before diving into the case studies, the following is a review of the physics and literature on how an ESP is impacted...

... Abstract Dual Electrical Submersible Pumps (ESPs) have gained widespread adoption across the oil industry. While current applications are predominated by identical size systems to achieve the sole goal of extended run life, incorporating different-sized systems can open the door for expanded...

... Abstract The behavior and survivability of electric submersible pumping systems (ESPs) used for hydrocarbon production vary from one condition to another. Sour environment is generally known to bring about stress cracking of some sort in well completion assembly. Regrettably, the pattern...

... wear. Plugged stages occur when large amounts of sand clog the flow vanes to the point where the flow area is 100% blocked. Sand accumulating at the pump discharge creates a heavy plug with back pressure on the pump; it is sometimes difficult to overcome when attempting to restart the ESP. Restarts...
