Abstract: An artificial lift system for a well has a surface unit and a subsurface pump. The surface unit reciprocates a rod in the well, and the pump disposed in a tubular in the well is actuated by the rod. A barrel of the pump has a standing valve restricting fluid passage out of the barrel. The plunger is reciprocally disposed in the barrel and has seals with the barrel. A traveling valve of the plunger uses a sleeve and a bob. The sleeve is movable relative to the bob to restrict fluid out of the plunger's interior through a variable gap relative to the bob and the sleeve. The filter is disposed on the plunger between the seals and separates the plunger's interior from an annulus between the plunger and the barrel. The filter restricts particulate in the interior from passing into the annulus.

The support member is configured to isolate the FBG sensor from strain in the optical fiber.

Abstract: In a deviated wellbore, a pump system computes downhole data from surface data by solving a wave equation that takes both viscous damping and Coulomb friction into consideration. Mechanical friction between the rods, couplings, and tubing is considered in the calculation of downhole data in the deviated wellbore by modelling the wellbore's trajectory, parameterizing various deviated segments (build-ups, slants, drop-offs, etc.) in the trajectory, mapping the rod string to the segments, and incrementally evaluating position of the mapped string over time in order to compute drag forces and side loads experienced by the rod string during operation. These computed drag forces and side loads are then used in the solution of the wave equation to solve the surface load and position data and provide more accurate downhole position and load data.

Abstract: Aspects of the present relate to automated load cell identification. A method is provided. The method generally includes sending, from a load cell to a remote processing system, identification information associated with the load cell; and determining whether the load cell is valid for use during makeup of a threaded connection of a first threaded tubular to a second threaded tubular based on the identification information associated with the load cell. The load cell identification information may include a measurement range of torque values supported by the load cell. The method can include comparing the measurement range of torque values to a job defined range of torque values associated with the makeup of the threaded connection; and determining that the load cell is valid for use based on the comparison. The identification information can be used to detect the load cell type, range, and calibration data before tubular makeup to ensure data quality and safety at work.

Abstract: A jarring device includes a housing, a mandrel received within the housing, and a pressure chamber defined between the housing and the mandrel and filled with a hydraulic fluid.

Abstract: Angular position readings are obtained during rotation of an apparatus in a borehole, and angular rate readings are obtained over time of the rotation. The angular rate readings are adjusted based at least on the angular position readings. The angular position measurement does not require calibrated magnetometers or accelerometers to function. Additionally, a dynamic scale factor calculation for an angular rate gyroscope (ARG) allows the ARG to be used over a much wider operating range than without such a calculation. Finally, an integrated angular rate from the ARG calibrated for bias and scale factor fills in positional information between the magnetometers' zero crossings to deliver a high resolution hybrid angular position system capable of measuring precise angular position at high and irregular downhole rotation rates.
