... 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...

... of the PCP system contributing to significant reduction in lifting cost per barrel fluid. The PCP has established its robustness being in operations for almost 30 years under varying well conditions such as increasing water-cuts and fluid production rates, decreasing reservoir pressures, fluctuating GOR's...

... Abstract The Cooper Basin is one of Australia's largest onshore resource projects. It is geographically located in central Australia in a remote and harsh area commonly known as the "Outback". On behalf of its joint venture partners, Santos operates more than 400 oil wells and 820 gas wells...

... and it’s been decided to accompany this pilot follow up with a dedicated software for Progressing Cavity Pumps (PCP) operations, called PCM Field Track. Significant Key Performance Indicators (KPI) and production parameters were identified and a uniform method for Failure Analysis has been implemented...

....) this program was unique in that it also assessed the performance of the same metallic PCP stator using two different PCP rotors, to mimic a rotor-swapping operation. Some of the challenges encountered during this test program including issues with the downhole completion, high levels of downhole vibration...

... Abstract The coal seam gas (CSG) industry is challenged to maximise gas recoverability while minimising the operational and maintenance costs of subsurface artificial lift technologies. Data acquisition is critical in both optimising assets and characterising early failure. Large data flows...

... Abstract Finding a reliable artificial lift pumping system for heavy oil thermal recovery has been a challenge mainly due to the high operating temperatures (>150°C). Available options such as Rod Pumps, Electrical Submersible Pumps (ESP) and Elastomer Progressive Cavity Pumps (PCP) have...

... 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...

... in the elastomeric stator. Thousands of data values were collected over a period of several months and evaluated to better understand rod stretch, torsion, and axial movement during start-up, shut-down and normal operating conditions and how these values change as a function of the interference fit of the pump...

... 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...
