A powered well string positioner capable of actuation during the vertical reciprocal movement of a well string will increase or decrease the length of the downhole well string length below the wellhead seal upon detection of a string positioning condition within the tubular by a controller. The vertical reciprocal stroke of the power unit of the well is not changed as the downhole length of the well string is varied, and the well string can be adjusted during operation of the well without the need to disassemble the well string.

An apparatus for monitoring rod rotation in a rod lift system. The apparatus comprises one or more sensors that reside on the rod string of the rod lift system. The sensor is configured via a processor to generate a signal indicative of radial position of the sensor relative to an external frame of reference. The signal may be sent to a wireless I/O module, with the signals being indicative of at least partial rotation or, alternatively, a lack of rotation, of the rod-string. The processor is configured to generate an alarm if an absence of rod rotation is detected while the rod lift system is running and transmit this signal to the nearby wireless I/O module. A method for monitoring a reciprocating rod lift system is also provided.

An apparatus and method for use in an artificial lift system to provide under pumping mitigation functionality in which a sucker rod pump's pumping speed is adjusted through the use of a controller that determines whether: (a) the fillage level of the pump is equal to or above a pre-determined fillage level and (b) whether the fluid level in the wellbore in which the pump is positioned is not decreasing and increases the pumping rate of the pump if, over a given period, both (i) the fluid level is not decreasing and (ii) the pump fillage level is above the predetermined fillage level.

A computer-implemented method for determining an operational property of a drill-rod borehole pump. A load-distance diagram with curve points for the pump is ascertained by an analysis device using a detection device and is provided as an operational load-distance diagram with operational curve points. Wherein in a training mode, a load-distance diagram model for the pump with model curve points is generated and trained on the basis of machine learning, at least two specified analysis regions are determined in the load-distance diagram model, and a reference point is ascertained from the model curve points of at least one region. In an operating mode for the operational load-distance diagram, a check is carried out to determine whether the at least one reference point is contained within the surface contained by the operational curve points, and if so, the operational property of the conveyor pump is determined therefrom.
