摘要： A system includes a dispensing device having a material chamber to store an oilfield material and to fluidly couple to a wellhead, a plurality of flow control devices to control a flow of the oilfield material via the material chamber, a plurality of sensors to measure one or more properties related to the dispensing device, and a control system communicatively coupled to the dispensing device. The control system opens a first flow control device to fill the material chamber with the oilfield material, monitors a condition associated with the material chamber based on the properties measured via the plurality of sensors, opens a second flow control device to provide a high pressure fluid into the material chamber when the condition is present, and open a third flow control device, where the third flow control device fluidly couples the material chamber to the wellhead.

摘要： A wellhead alignment system includes a visual marker configured to be placed at a wellhead and a camera configured to capture an image that includes the visual marker. The wellhead alignment system also includes one or more processors configured to apply computer vision algorithms to identify the visual marker in the image and to calculate an offset between the wellhead and a drilling rig based on a position of the visual marker in the image.

摘要： Systems and methods presented herein generally relate to greenhouse gas emission monitoring and, more particularly, to a greenhouse gas emission monitoring workflow using various different types of sensors. For example, a system includes a plurality of sensors located within an oil and gas worksite. At least one sensor of the plurality of sensors is configured to detect a status of equipment at the oil and gas worksite. The system also includes a greenhouse gas emission analysis system configured to receive sensor data from the plurality of sensors. The greenhouse gas emission analysis system is also configured to correlate the sensor data from the plurality of sensors (e.g., using one or more reduced order models (ROMs) that reduce the computational complexity of computational fluid dynamics model simulations of previously collected data relating to operation of the oil and gas worksite). The greenhouse gas emission analysis system is further configured to determine an existence of a greenhouse gas emission within the oil and gas worksite, a location of the greenhouse gas emission within the oil and gas worksite, and a quantity of the greenhouse gas emission within the oil and gas worksite based at least in part on the correlation.

摘要： A fracturing fluid delivery system is provided. In one embodiment, the system includes a fracturing manifold and a fracturing tree. A fluid conduit is coupled between the fracturing manifold and the fracturing tree to enable receipt of fracturing fluid by the fracturing tree from the fracturing manifold through the fluid conduit. Further, the fluid conduit is an adjustable fluid conduit that provides a line-of-sight fluid connection from the fracturing manifold to the fracturing tree. Additional systems, devices, and methods are also disclosed.

摘要： 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.

摘要： 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.
