摘要： A method can include, for a control action for a hydraulic fracturing operation of a well, using a trained machine learning model that predicts treatment pressure of the hydraulic fracturing operation, determining if the control action increases efficiency; if the control action increases efficiency, assessing viability of the control action with respect to one or more predefined criteria; and, if the control action is viable, issuing the control action for implementation during the hydraulic fracturing operation.

摘要： A system and method use a sensor embedded in flexible tape to monitor for corrosion of a structure, such as a conveyance line in a well. The system comprises the structure, a spool, a flexible tape, a sensor, a spool driver, and a processor. The structure includes a window adjacent to an element under test. The flexible tape is retained by the spool. The sensor is embedded in the tape, with the sensor being configured to detect a corrosion of the element and to generate corresponding sensor data. The spool driver is coupled to the spool and advances the tape from the spool to position the sensor adjacent to the window, thereby to position the sensor adjacent to the element to detect the corrosion. The processor is configured by code stored therein to receive the sensor data and to generate and output an alert of the detected corrosion.

摘要： Through-tubing, cased-hole sealed material density can be evaluated using gamma ray measurements. Density evaluation comprises detecting, by at least one detector positioned within a casing of a wellbore including a sealing material positioned between the casing and a subsurface formation, electromagnetic radiation generated in response to nuclear radiation being emitted outward toward the subsurface formation, determining an electromagnetic radiation count based on the detected electromagnetic radiation, selecting at least one of a first reference material having a density that is less than a density of the sealing material and a second reference material having a density that is greater than the density of the sealing material, adjusting the electromagnetic radiation count based on the density of the at least one of the first reference material and the second reference material, and determining a density of the sealing material based on the adjusted electromagnetic radiation count.

摘要： A method includes assembling a liner system by disposing a fiber optic cable circumferentially around an inner tube liner and locating an outer tube liner around the inner tube liner. The fiber optic cable is located between the inner tube liner and the outer tube liner. The method also includes spooling out the liner system, in a lay-flat state, into a conduit of a tubular structure positioned in the well, terminating spooling out the liner system when a select length of the liner system has been deployed in the conduit of the tubular structure, and securing the select length of the liner system deployed into the tubular structure at a surface above the well. The method further includes injecting a fluid into the inner tube liner of the liner system to radially expand the liner system to conform an outer circumferential surface of the outer tube liner to an inner circumferential surface of the tubular structure, protecting the inner circumferential surface of the tubular structure using the liner system, and measuring a property of the well using the fiber optic cable.

摘要： Methods, systems and devices are disclosed for controlling self-induced acoustic interference. In one embodiment, a first piezoelectric transducer to which a first excitation signal is applied, generates back side acoustic waves that are transmitted from a back side of the first piezoelectric transducer into a backing material layer. A second piezoelectric transducer coupled to a back side of the backing material layer generates a first calibration response to the back side acoustic waves. An interference signal profile is generated based, at least in part, on the first calibration response and may be used to filter interference signal components and/or to generate a control signal to be applied to the second piezoelectric transducer during measurement cycles.

摘要： A computerized method for management of a slurry injection well and the associated surface facility. The method utilizes real time and historical data of injection and slurry parameters in conjunction with computer simulations on a computer-modelled reservoir to predict well behavior during one or a series of injection events. The system determines optimized injection operation schedules, recommends and implements changes to an injection operation, including while in process such as through automated equipment control.

摘要： A method for predicting fracture treatment performance includes inducing tube waves in a well drilled through a formation to be fracture treated. A polarity of reflected tube waves in the well is determined, and using the reflected tube waves, hydraulic conductivity of at least one zone in the well hydraulically connected to the formation is estimated. The estimated hydraulic conductivity is compared to a selected threshold. The selected threshold is based on pumping parameters and pumping pressure behavior of at least one pumped hydraulic fracture treatment. A warning signal is generated when the hydraulic conductivity is below the selected threshold and/or the determined polarity indicates a closed boundary condition so that the treatment may be adjusted to avoid screenouts and other operational and treatment issues.

摘要： Tubular cut monitoring systems and methods to cut a tubular are presented. The method includes running a downhole cutting tool to a location in a tubular. During a cutting operation, the method also includes monitoring, with an inertial sensor of the downhole cutting tool, for stick slip vibrations produced by a cutter blade of the downhole cutting tool. The method further includes determining whether a total number of stick slip vibrations produced by the cutter blade within a threshold number of revolutions of the cutter blade is greater than a threshold number of tolerable stick slip vibrations. In response to a determination that the total number of stick slip vibrations produced by the cutter blade within the threshold number of revolutions is greater than the threshold number of tolerable tick slip vibrations, the method further includes ceasing the cutting operation.
