Paper presented at the SPE Progressing Cavity Pumps Conference, August 25–27, 2013
Paper Number: SPE-165067-MS
... Investigated PCP failure cases of four wells A, B, C and D meet manufacturers’ minimum required pump conditions which have realized pump lifetimes beyond 5 years. Bind assumption is that the pump is correctly spaced out. This correlation results into two characteristics domains taking...

Paper presented at the SPE Progressing Cavity Pumps Conference, August 25–27, 2013
Paper Number: SPE-165648-MS
... Abstract An innovative ES-PCP system has been developed in conjunction with a major operator and has now entered field trials. The system enables rig-less deployment capability on coiled tubing, and is compatible with conventional jointed tubing. It fundamentally addresses many of the issues...

Paper presented at the SPE Progressing Cavity Pumps Conference, August 25–27, 2013
Paper Number: SPE-165650-MS
... Abstract Progressing Cavity Pumps (PCP) are positive-displacement pumps customarily employed in the petroleum industry for artificial lift of high viscosity oils, or fluids with moderate degree of gas and/or sediments. Basically, an elastomeric PCP consists of a metallic helical rotor...

Paper presented at the SPE Progressing Cavity Pumps Conference, August 25–27, 2013
Paper Number: SPE-165654-MS
... Abstract Although conventional rod driven Progressing Cavity Pumps (PCPs) have been in use since the early 1980‘s, the industry has continued to seek alternative methods of powering the system. Initial attempts were made using conventional electric submersible induction motors however...

Paper presented at the SPE Progressing Cavity Pumps Conference, August 25–27, 2013
Paper Number: SPE-165645-MS
... Abstract In a progressive cavity pump (PCP), the rubber stator is not only susceptible to damage, and thus is a major factor affecting the pump’s performance. To date, however, an experimental method to test the deformation and forced state of the elastomer of a stator under real operating...

... and monitoring their PCP pumps with digital downhole sensors. Without sensors monitoring the lift systems, the operator would not know what component downhole is causing lost production and if adjustments could be made at the surface to increase productivity. One year following the installation of the PCP...

Paper presented at the SPE Progressing Cavity Pumps Conference, September 12–14, 2010
Paper Number: SPE-137208-MS
... Abstract PCP technology has progressed to enable their application in high temperature environments. Typically PCP elastomers limited the temperature range for operation to approximately 150C, but the recent introduction of metal to metal pumps has removed this ceiling. Operation above 150C...

... of progressing cavity pump (PCP) wells, traditional PCP system design couldn’t meet the requirement of well logging for separated layer production. Since separate layer development technology is more and more popular in oilfield development, PCP logging technique has become a bottleneck issue which limited PCP...

Paper presented at the SPE Progressing Cavity Pumps Conference, September 12–14, 2010
Paper Number: SPE-136817-MS
... PCP is known for their simplicity of design and operation. The heart of the pump is composed of two parts, the stator and the rotor. The stator has a dual helical profile, while the rotor (which rotates inside the stator) has a single helical profile, designed to mate with the stator profile...

Paper Number: SPE-137168-MS
... For PCP in multiphase flow (test run at 90% gas void fraction (GVF)), the compression takes places in the last stages, near the pump delivery side. The temperature measured in this area increases dramatically as well. The hysteresis effect mentionned earlier becomes the number one cause for pump...

Paper presented at the SPE Progressing Cavity Pumps Conference, April 27–29, 2008
Paper Number: SPE-112881-MS
... Abstract Progressive cavity pumps (PCPs) are usually driven at surface through sucker rods. Due to the shear strength of sucker rods and the wear of the rod and tubing, the surface drive system limits its application in production rate and well depth, and in deviated and horizontal wells...

... pumping system was not as economic as other in blocks of Daqing Oilfield. As the result, PCP was put into production from 2005. Though all the four wells had a good performance with high pumping efficiency in the beginning, after several months' operation, rod strings suffered from severe oscillation...
