Abstract: A technique facilitates fluid flow measurement by providing a meter able to accurately monitor fluid flow of a liquid even if gas is present in the liquid. The meter may comprise a tubing with an internal flow passage and a wedge or other restriction extending into the internal flow passage. A first port is located upstream of the restriction and a second port is located downstream of the restriction to enable monitoring of a differential pressure across the restriction. The differential pressure can be used to determine the desired flow parameter, e.g. volumetric flow. The system facilitates separation of gas from the liquid and utilizes a gas bypass. The gas bypass routes the separated gas past the restriction, e.g. wedge, before directing the gas back into the fluid flow path.

Abstract: A progressive cavity pump (PCP) system includes a PCP with a rotor rotatably disposed in a stator, a permanent magnet motor, sucker rod(s), and a control system. The rotor is coupled to one of the sucker rods via a high-torque connection that allows for counter clockwise rotation without loosening the connection between the rotor and sucker rod. The control system operates the system in a production mode by rotating the rotor clockwise. Upon manual input by a user, or automatic triggering when protections settings of the control system call for a shutdown or cleanout or when the control system senses an imminent pump shutdown, the control system operates the system in a reverse mode by rotating the rotor counterclockwise. The reverse mode pumps fluids and suspended solid particles down into the well prior to pump shutdown to inhibit the solids from clogging the pump or preventing the pump from restarting.
