The oilfield operator last year decided to renew and upgrade their pumping equipment, including 10 production wells. Oil Dynamics convinced the customer with its modular technical concept being able to cope with wide variations of reservoir pressure. The tailor-designed and 100%-tested equipment has been commissioned by Oil Dynamic’s factory-own Field Service, which also established a data connection to the client’s control system.
Meanwhile the first two wells were upgraded from Progressing Cavity Pumps (PCP) to Electric Submersible Pumps (ESP) and are running. “Comparing the same sizes, ESPs can deliver higher flowrates and heads, are more energy efficient and longer lasting than PCPs”, said Adam Waniek, Sales Manager Europe at Oil Dynamics. ESP installations have smaller footprints on surface and emit no noise, he said. Unlike PCPs, an ESP does not need any drive shaft going through the wellhead nor mechanical seal, which makes ESP completions safer, not least for the environment.
Both ESP-systems commissioned to the customer near Hannover were equipped with pump sensors. Those downhole sensors constantly deliver important values to the surface such as downhole pressure, temperature, etc. When this information is properly processed, Oil Dynamics guarantees a better reservoir management, production control and pump protection are guaranteed, among other things. To power and control the ESPs Oil Dynamics also built and commissioned new Variable Frequency Drives (VFDs). The ElektroMotion smartDRIVEs in use were built with selected high-quality industrial components from the global market. Also, the delivered VFDs were equipped with DC-link chokes for the intermediate circuit and du/dt sinusoidal wave filters on the output side. These additional components improve the power quality on both sides of the VFD, extending the service life of the pump motor and neighbouring electrical systems.
