Abstract: A system includes a hanger with a radially-outer surface with a hanger surface texture. The system also includes a sensor configured to detect vibrations induced by the hanger surface texture as the hanger moves through a housing of a wellhead. The system further includes a controller configured to receive signals indicative of the vibrations from the sensor and to process the signals to determine a position of the hanger within the housing of the wellhead.

Abstract: A fracturing fluid delivery system having a fracturing line with a flexible liner is provided. In one embodiment, a method includes moving a flexible polymeric liner through a bore of a fracturing line to a position in which the flexible polymeric liner extends along an inner wall of a flexible pipe body of the fracturing line. The method also includes securing the flexible polymeric liner in the bore of the fracturing line, such as by attaching the flexible polymeric liner to an opposing surface of the fracturing line. Additional systems, devices, and methods are also disclosed.

Abstract: A system including a valve. The valve includes a valve body having an interior volume and a bore along a first axis. A stem extends along a second axis and a flow control element couples to the stem. The stem selectively moves the flow control element through the interior volume between a closed position and an open position relative to the bore. A valve insert system retains a pressurized lubricant in the interior volume.

Abstract: A technique facilitates greasing of valves on a well tree, e.g. a frac tree, according to a simple process which enables selected, individual valves to be greased when desired. In some applications, the greasing process may be automated and controlled via a greasing control system. According to an embodiment, a greasing system is connected with grease ports at a plurality of actuatable valves located in a well tree. The greasing system has a plurality of grease valves which may be associated with each of the actuatable valves, e.g. with each of the grease ports. A pump is used to pump grease to the grease valves and the grease valves are selectively actuated to open positions to provide controlled greasing of desired actuatable valves so as to remove debris from and to lubricate selected actuatable valves.

Abstract: A system that includes a wellhead. The wellhead defines a bore. A hanger system is positioned within the wellhead. The hanger system includes a piston angled relative to a longitudinal axis of the bore. A first spring biases the piston in a first direction. The piston contacts a slip segment to couple the slip segment to a casing string.

Abstract: Smart wellhead assemblies with sensors for detecting positions of components within the bores of the wellhead assemblies are provided. In some instances, the sensors can be used to detect one or more of landing, locking, or concentricity of hangers, packoffs, or other internal wellhead components within bores. In one example, a method of installing a hanger within a wellhead includes lowering the hanger within the wellhead and using one or more sensors to detect when the hanger is at a target location. The method can also include activating a locking mechanism of the hanger and using the one or more sensors to detect when the locking mechanism has secured the hanger within the wellhead. Additional systems, devices, and methods are also disclosed.

Abstract: A technique facilitates performance of well operations. According to an embodiment, the technique employs a modular assembly configured for coupling with a wellhead assembly. The modular assembly may have a production subassembly and a fracturing subassembly. By way of example, the production subassembly may comprise a connection block positioned for coupling to the wellhead assembly, a production outlet fluidly connected to the connection block, and a valve between the connection block and the production outlet. Additionally, the fracturing subassembly may be releasably coupled to the production subassembly. According to an embodiment, the fracturing subassembly comprises an inlet for receiving fracturing fluids, an outlet coupled to the connection block, and a bore between the inlet and the outlet for communicating a fracturing fluid to a well.

Abstract: A flowmeter body assembly includes a flowmeter body defining a central bore and a plurality of angled connectors extending from a sidewall of the flowmeter body. The flowmeter body and the plurality of angled connectors form a one-piece structure that is devoid of welded joints, and each of the plurality of angled connectors is configured to support a respective sensor to enable measurement of a flow rate of a fluid across at least one chordal plane of the flowmeter body.
