摘要： A well system can include a completion string adjacent to a target formation and a service tool extending within the completion string. When the service tool is in an aligned position with respect to the completion string, the service tool can prevent fluid communication between the target formation and a return conduit to facilitate fluid slurry injection. In such an alignment, a reader of the service tool is positioned within a threshold distance of a tag of the completion string to receive an indicator from the tag. From the tag, the reader receives confirmation that the service tool and the completion string are properly aligned. A pulser of the service tool transmits a signal to a surface location to convey the confirmation. A user may then pump the fluid slurry through an internal fluid flow passage of the service tool to the target formation.

摘要： A method for drilling a new oil or gas well in a selected geographical location comprises extracting drilling modes from historic drilling data obtained from a group of drilled wells in the selected geographical location using a pattern recognition model. Each drilling mode represents a distinct pattern that quantifies at least two drilling variables at a specified drilling depth. The method also comprises selecting a sequence of drilling modes at positions along a reference well as reference drilling modes that represent more efficient values for a selection of one or more of the at least two drilling variables compared to other extracted drilling modes; associating drilling parameter settings with the reference drilling modes; and drilling the new oil or gas well applying at least some of the drilling parameter settings.

摘要： Methods, apparatuses, and computer readable medium including computer program products, are provided for determining the depth of water in a well. A method may include coupling a signal onto a cable connected to a submersible well pump. The method may further include monitoring the cable to determine a first time corresponding to a first reflection of the signal caused by the cable entering a water column between a water surface and the submersible pump. The method may further include monitoring the cable to determine a second time corresponding to a second reflection of the signal caused by an impedance mismatch between the cable surrounded by water and a motor in the submersible well pump. The method may further include determining a water height between the submersible pump and the water surface from the first time and the second time.

摘要： A system and method for downhole data communication using an infrasound wave generator (26) and receivers (28 ). The infrasound waves (30) have a low frequency and a wavelength that is much larger than the transverse dimensions of the well (10). When the infrasound waves (30) are directed down the well (10), the well (10) will act as a wave guide for low frequency excitations. The receivers (28) are operatively connected to inflow valves (23) and other downhole equipment, and receive the infrasound waves (30). If the waves (30) are of a predetermined frequency, the receivers (28) command the valves to open or close, or otherwise control downhole equipment. The infrasound waves (30) can also be used to probe well (10) geometry and to identify fluid properties within the well (10).

摘要： This disclosure relates to a system and method for detecting structural integrity of a well casing. The system may detect casing structural integrity events. The casing structural integrity events may include structural failures of the casing and/or potential structural failures of the casing. The well casing may be drilled and/or otherwise embedded into a geologic structure. The well casing may be subject to geologic forces generated by the geologic structure. Unplanned and/or unexpected forces and/or movement may pose a risk to the structural integrity of the casing. Forces and/or movement of sufficient magnitude may result in damage to and/or destruction of the casing. Damage to and/or destruction of the casing may cause a loss of the natural resources being extracted via the well associated with the well casing, contamination of areas surrounding the well, undesirable surface expression, and/or other negative effects.

摘要： A tubular assembly is disclosed for use in a wellbore (5) of an oil, gas or water well, typically for landing a downhole device in the wellbore. The assembly has a sleeve (1) adapted to receive the body of the downhole device. The sleeve is deployed into a conduit in the wellbore and expanded, so that the outer circumferential surface of the sleeve is radially expanded against the inner surface of the conduit. The sleeve has a bore with an inner circumferential surface comprising an inwardly facing formation adapted to engage with an outwardly facing formation on the body of the downhole device when the body of the downhole device is disposed in the bore of the sleeve. The sleeve is typically deployed in the wellbore at the desired location and is radially expanded by an expander device (2) that is deployed within the bore of the sleeve. The expanded sleeve plastically deforms and retains its expanded configuration after the radial expansion force is removed from the sleeve. The sleeve provides a modular anchoring or landing point in the wellbore that can be retrospectively set in the conduit at different locations, and various downhole devices can then be deployed into the sleeves at predictable depths and a reliable connection can be made with the sleeve. The assembly can typically pass through a smaller diameter before being morphed to seal and anchor in a larger diameter.

摘要： A method for drill pipe tallying includes detecting that a drill bit has tripped in through a rig floor and monitoring movement of a drawworks that supports the drill bit and a length of drill pipe. If a tag interrogating device does not detect a wireless tag associated with a set of slips, the method includes counting the movement of the drawworks toward a drill pipe tally. If a tag interrogating device detects a wireless tag associated with a set of slips, the method includes not counting the movement of the drawworks toward the drill pipe tally. The tag interrogating device is positioned at a fixed location relative to the rig floor.
