Abstract: The disclosure relates to an emissions detector for monitoring methane emissions at one or more industrial facilities. The emissions detector includes: a pole; an enclosure mounted on the pole, wherein the enclosure houses at least one sensor, wherein the at least one sensor includes a gas sensor configured to measure concentration of methane in atmospheric gas that flows into the enclosure; and means for removably securing the pole to ground without the use of concrete.

Abstract: A monitoring system operable to monitor an oilfield additive system having multiple components. The oilfield additive system is operable to transfer an additive-containing substance for injection into a wellbore. The monitoring system includes sensors each associated with, and operable to generate information related to an operational parameter of, a corresponding one of the oilfield additive system components. The monitoring system also includes a monitoring device in communication with the sensors and operable to record the information generated by the sensors to generate a database. The database includes information indicative of maintenance aspects of the oilfield additive system and/or the oilfield additive system components.

Abstract: A technique facilitates use of tools downhole during well operations. According to an embodiment, the technique employs a frac stack which may be coupled to a wellhead. The frac stack may include a flow control device which opens and closes a bore extending through the wellhead. A lubricator may be coupled to the frac stack. The lubricator includes a tool trap which opens and closes to facilitate controlled movement of a tool along the bore. A tool position detection system is used to detect a position of the tool in the tool trap to ensure, for example, removal of the tool from the frac stack before closure of the flow control device.

Abstract: Systems and method for controlling wellsite equipment, including pumps and a manifold having a low-pressure (LP) manifold, having LP ports with LP valves, and a high-pressure (HP) manifold, having HP ports with HP valves and bleed ports with bleed valves. The pumps are fluidly coupled with the LP manifold via LP conduits and with the HP manifold via HP conduits. Communication is established between a controller and the LP valves, the HP valves, the bleed valves, the pumps, and sensors for monitoring pressure within the HP conduits. The controller is operable to, with respect to each pump, cause the LP valve to transition to a closed position, cause the HP and/or bleed valve to transition to an open position, and determine that the HP conduit is not pressurized based on the information generated by the sensors.
