Oil Dynamics GmbH has recently upgraded the first two of ten production wells for an oilfield operator who decided to renew and enhance pumping equipment at its site near Hannover, Germany.
Oil Dynamics upgraded the wells from Progressing Cavity Pumps (PCPs) to Electric Submersible Pumps (ESPs). Adam Waniek, sales manager Europe at Oil Dynamics, said that when comparing the same sizes, ESPs can deliver higher flowrates and heads, are more energy efficient and longer lasting than PCPs.
ESP installations also have smaller footprints and emit no noise. Unlike PCPs, an ESP does not need any drive shaft going through the wellhead nor mechanical seal, which makes ESP completions safer, especially for the environment.
Both ESP-systems commissioned to the client were equipped with pump sensors. The downhole sensors constantly deliver important values to the surface such as downhole pressure and temperature.
Oil Dynamics also built and commissioned new Variable Frequency Drives (VFDs). The ElektroMotion smartDRIVEs were built with selected high-quality industrial components and equipped with DC-link chokes for the intermediate circuit and du/dt sinusoidal wave filters on the output side.
