摘要： A method for 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： Methods and systems for controlling a drilling operation based on an MSE value calculated for a depth increment are disclosed herein. In an exemplary method, drilling parameters characterizing a drilling operation in a subterranean formation are received in a control system. The drilling parameters are used by the control system to calculate a depth-based mechanical specific energy (MSE) based on some amount of energy expended by at least a portion of a drilling assembly while drilling at least one identified depth sub-interval of a depth interval of a subterranean formation. The control system uses the calculated depth-based MSE to control the drilling operation.

摘要： A method for completing a wellbore in a subsurface formation includes providing a first base pipe and a second base pipe. Each base pipe comprises a tubular body forming a primary flow path. Each base pipe has transport conduits along an outer diameter for transporting fluids as a secondary flow path. The method also includes connecting the base pipes using a coupling assembly. The coupling assembly has a manifold, and a flow port adjacent the manifold that places the primary flow path in fluid communication with the secondary flow path. The method also includes running the base pipes into the wellbore, and then causing fluid to travel between the primary and secondary flow paths. A sand screen assembly is also provided that allows for control of fluid between primary and secondary flow paths.

摘要： A system for downhole telemetry employs a series of communications nodes spaced along a tubular body such as a pipe in a wellbore. The nodes allow for hybrid wired-and-wireless communication between one or more sensors residing at the level of a subsurface formation, and a receiver at the surface. The communications nodes employ electro-acoustic transducers that provide for node-to-node communication partially up a wellbore, and then high speed data transmission using a wire for the remaining distance up to the surface. A method of transmitting data in a wellbore uses a plurality of data transmission nodes situated along a tubular body to deliver wireless signals partially up the wellbore, and then wired signals the remaining distance.
