ESPCP System Increased Run Life 433% in CongoLonger run life reduced production cost and decreased workover rate
Baker Hughes was approached by the operator of a problem well located offshore Pointe Noire, Congo. The well was experiencing a mean time between failure rate of 90 days with a rod-driven progressing cavity pump (RDPCP™). The operator initially selected PCP technology due to the challenging environment of aggressive sediment that could not be handled by other forms of artificial lift. However, this particular well was drilled with a high dogleg severity rate that caused parted sucker rods 13 times over three years.
Baker Hughes and the operator joined forces to find an alternative artificial lift form that could both handle the sediment production and high DLS. The conclusion was to install a Baker Hughes ESPCP™ system. This uses a PCP’s ability to handle high sand production while leveraging a field-proven downhole motor to drive the system and eliminate the sucker rod string.
To design the proper ESPCP system for this particular application, the Baker Hughes PCP applications engineering team simulated the reservoir conditions using Baker Hughes AutographPC™ software, the artificial lift industry’s most comprehensive and user-friendly design software, to select the most appropriate form of artificial lift for this well.
