    摘要： The present application describes a method and modeling system for managing and modeling well completions. The method includes constructing a wellbore model of a completion. Then, the wellbore model may be applied to generate one or more simulated production profiles, wherein the simulated production profiles include two or more of pressures associated to depth, temperatures associated to depth, flow rates associated to depth, fluid flow velocities associated to depth, and any combination thereof. The completion and one or more sensors may be disposed into a well. Sensory data may be acquired or obtained from the sensors associated with the completion. The sensory data is examined to determine if production conditions have changed. If the production conditions have changed, one or more measured production profiles are generated from the sensory data and are compared to the at least one simulated production profile to determine a modification to the completion. Then, the completion is modified based of the determination. However, if the production conditions have not changed, well operations continue.

    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.

    摘要： A fluid control valve trim and seat with a valve plug of a radius of about 0.03 inch, when used in conjunction with a valve seat angle of about 75°, results in minimal unbalance area. The valve trim is provided with pairs of anti-cavitation notches. The notches are arranged such that notches of each given pair are angled with respect to one another, and may be further arranged such that adjacent pairs of notches are off-set relative to one another, so as to increase the time fluid spends in the plenum, resulting in proper staging and controlled pressure drop as fluid passes through the valve.
