Paper: OPTIMIZING ARTIFICIAL LIFT OPERATIONS THROUGH THE USE OF WIRELESS CONVEYED REAL TIME BOTTOM HOLE DATA

A field demonstration of the application of the bottom hole pressure data, as received from Real Time Diagnostics" wireless pressure transmission system, improved the efficiency of PanCanadian Petroleum Limited's 8A-19-38-Ol-W4m well in the North Bodo field of northeast Alberta, Canada. An illustration of servicing a typical North Bodo slant well on a pad of wells is shown in Figure 1. The Telemetry Acquisition Tool (TAS device, developed by Real Time Diagnostics (RTD), was installed in the production tubing below the producing zone perforations, where it was able to measure and accurately transmit bottom hole production pressures and temperatures of the well's producing horizon to the surface. The real time pressure data was relayed into a voltage loop and a surface computer which contained software designed to output an analog process signal. This signal was then sent to the Wermac Electric Limited's Variable Frequency Drive (VFD), which controls the speed and torque of the electric motor powering the bottom hole progressive cavity pump (PCP) system. PanCanadian was able to both increase the oil production and decrease the lifting costs per barrel by utilizing the actual bottom hole pressure response of the reservoir fluids flowing into the wellbore to optimize the daily rate of production.
