Schneider Electric’s three solution architectures are specifically designed for the digital oil field (DOF) and are ready for use in more than two million rod pump wells worldwide. Built upon Schneider Electric’s Rod Pump Controller (RPC) function, the solutions enable significant savings, improve productivity, decrease energy use and avoid superfluous maintenance costs by analyzing system operations and adjusting to changing demands and pump speeds. Equipment life is extended by reducing electrical/mechanical stress, temperature, negative torque, minimizing rod breaks, providing near-unity power factor at all speeds and loads to avoid utility penalties and achieving greater energy efficiency.

The three pump rod control solutions are designed to meet the needs of different well types as an independent system or combined with other Schneider Electric equipment and technologies to deploy a comprehensive DOF solution. The torque control rod pump solution is designed for shallow wells, and automatically adjusts to changing conditions – eliminating the need for a separate pump off control timer, ensuring minimum off-time and maximum recovery. The surface card control leverages data gleaned from an external load cell, enabling it to increase well-depth optimization and integrate third party analysis and operation functions.

The down-hole card control, optimizes well data, allows for visual system tuning and provides an advanced algorithm to maintain pump fill – fully optimizing production and equipment operation. This particular solution also analyzes each pump stroke, continually optimizing well performance even under changing conditions. The data gained from this function is able to be used for advanced diagnostics on well performance, and helps to identify issues which limit production or damage equipment.
