LIFTEQ ESPCP Improved Run Time 800% in Harsh California WellESPCP system saved operator USD 232,000 in annual OPEX
A California operator drilled a new well into a moderately deep zone, approximately 4,500 ft measured depth (MD)/3,800 ft true vertical depth (TVD). The first electrical submersible pump (ESP) installation failed after 134 days due to scale plugging. The well was treated with acid and a new ESP was installed. This system failed after 170 days due to heavy scale.
Baker Hughes designed a LIFTEQ™ electrical submersible progressing cavity pump (ESPCP™) system to significantly reduce the chance of plugging off with scale while improving run life and reliability. The combination of a large cavity opening and the elastomer in the positive displacement pump allowed scale to more easily pass through without attaching to the pump’s internal components. Additionally, the rotor was able to withstand the initial exposure to organic acid used by the operator to remove scale already in the perforations and the formation.
The ESPCP was installed and ran trouble-free for 1,338 days, producing 30 BOPD before replacement. The customer was so pleased with the performance and reliability that an additional ESPCP was installed. Baker Hughes engineers optimized the new pump design based on performance of the prior pump, additionally increasing oil production to 40 BOPD, adding USD 30,400* revenue per month.
