摘要： A flow meter system and method are provided for monitoring gas flow in a conduit. The flow meter system includes a plurality of components including: a sensor for sensing a flow rate of the gas flow; a communication device for transmitting information corresponding to the sensed flow rate to a remote device; an energy harvesting device for producing electrical energy from the gas flow to power operation of the communication device or other component of the flow meter system; and an energy storage device for storing electrical energy generated by the energy harvesting device.

摘要： System/method for real-time monitoring and control of pump operations at a well provide a pump control system that uses pump fillage with a proportional-integral-differential (PID) based algorithm to control positive displacement pump operations. The pump control system/method obtains measured or inferred pump speed from available pump speed data and, using certain pump characteristics provided by the well operator, calculates a theoretical fluid flow rate based on the pump speed. The pump control system/method thereafter compares the calculated theoretical fluid flow rate to a measured or observed fluid flow rate to calculate a pump fillage. The calculated pump fillage is then provided as a process input to the PID based algorithm along with a desired pump fillage from the well operator. The PID based algorithm processes the calculated pump fillage and the desired pump fillage using tuning parameters to determine an optimum pump speed based on the desired pump fillage.

摘要： A single pump control system monitors and controls oil and gas production operations at multiple wells. The pump control system analyzes operation data from multiple well pumps to independently and concurrently control operation of each well pump. The system obtains the operation data from sensors mounted at suitable locations around the wells. The data is then processed by pump control algorithms in the pump control system, each control algorithm applicable to and operable on a separate well pump. The pump control algorithms determine whether a well pump should be started, stopped, continue to run, and an optimal speed at which each running pump should run to maintain a cost-effective operation. Such an arrangement allows a single pump control system to automatically and independently control multiple different well pumps to optimize oil and gas production at each well.

摘要： Systems and methods provide real-time optical monitoring and control of well operations using digital cameras and image analysis. The systems and methods deploy one or more digital cameras in place of or in addition to conventional sensors to capture images of a well pump during well operations. The images may then be analyzed using image analysis algorithms and programs to measure a height, position, shape, and other measurements for certain components of the well pump relative to previous images. These image-based measurements may then be used to determine various operational parameters, such as pump speed, pump load, and other operational parameters. The operational parameters may then be processed by a pump control system to optimize pump operations based on the operational parameters.

摘要： Systems and methods for providing power to devices at a well site employ a linear alternator to generate power at a well site. The linear alternator is mounted on a pump at the well site and uses the up-and-down motion of the pump to generate power. The pump may be a nodding donkey head pump or other sucker rod pump mechanisms that operate based on linear vertical motion. The linear vertical motion drives a linear rotor back and forth through a linear stator to induce current in the linear alternator. This allows the linear alternator to convert a portion of the mechanical work performed by the pump into electrical energy that can be supplied to the devices. In some embodiments, the pump-mounted linear alternator can be equipped with a position sensor to directly measure a vertical position of the pump as the alternator travels up and down with the pump.
