摘要： Downhole plugs including a sensor, hydrocarbon wells including the downhole plugs, and methods of operating the hydrocarbon wells. The downhole plugs include a sealing structure, an actuation mechanism, and the sensor. The actuation mechanism is configured to selectively transition the sealing structure between a disengaged state, in which the downhole plug is free to move within a tubular conduit of a downhole tubular of the hydrocarbon well, and an engaged state, in which the sealing structure operatively engages with the downhole tubular, forms a fluid seal with the downhole tubular, and resists motion of the downhole plug within the tubular conduit. The sensor is configured to detect a sensed parameter within the tubular conduit and to generate a sensor signal indicative of the sensed parameter.

摘要： Evaluating annulus-tubing communication points in a production well having an annulus between a production string and a surrounding string(s) of casing. Determining a composition of production fluids produced from the well, and injecting one or more tracer materials into the annulus of the well under pressure as part of a lift gas. Each of the one or more tracer materials defines a material that is not native to the production fluids, and each has a different rate of diffusivity in the lift gas. The tracer materials are detected upon being produced at the surface. A mass spectrometer or other analyzer capable of detecting tracer materials at concentrations of less than 1,000 ppm is used. Determining injection points of the one or more tracer materials, and determining whether each of the injection points represents a gas lift valve along the production tubing.

摘要： Method for determining the depth of entry of lift gas into a production tube of a gas lift well includes the step of determining the concentration of GCOI endogenous to formation gas produced from the production tube of a gas lift well and absent from gas used as the lift gas in said gas lift well versus time after a perturbation of the rate of introduction of said lift gas into said production tube via one or more gas lift valves. The invention includes a system configured for evaluating the performance of gas lift well, including a separator, a flow regulation device, a measurement device for measuring over time the concentration of a GCOI in production fluids, a data collection and storage device for recording data from the measurement device, and a computer program product embodied on a computer-readable medium for analyzing the data collected by the measuring device.
