摘要： Embodiments of the invention provide an untethered apparatus for measuring properties along a subterranean well. According to at least one embodiment, the untethered apparatus includes a housing, and one or more sensors configured to measure data along the subterranean well. The data includes one or more physical, chemical, geological or structural properties in the subterranean well. The untethered apparatus further includes a processor configured to control the one or more sensors measuring the data and to store the measured data, and a transmitter configured to transmit the measured data to a receiver arranged external to the subterranean well. Further, the untethered apparatus includes a controller configured to control the buoyancy or the drag of the untethered apparatus to control a position of the untethered apparatus in the subterranean well. The processor includes instructions defining measurement parameters for the one or more sensors of the untethered apparatus within the subterranean well.

摘要： A method for logging in a well is disclosed. The method includes securing a passive logging while levitating (PLWL) assembly to a bottomhole assembly (BHA) to form a logging assembly and running the logging assembly into a wellbore of the well. The method further includes detecting a deviation in the wellbore, detecting a fluid flow direction around the logging assembly in the wellbore, activating the PLWL assembly based, at least in part, on the deviation in the wellbore and the fluid flow direction, and levitating the logging assembly in a center of the wellbore. The method also includes determining whether the logging assembly has reached a target depth and performing logging in the well while the logging assembly is levitating in the center of the wellbore.

摘要： This disclosure discusses methods and apparatus for generating vertical seismic profiles of a subsurface formation though deploying an untethered downhole tool into a wellbore, the untethered tool including at least one seismic sensor, a ballast, and a first electromagnet in the untethered downhole tool to attach the untethered downhole tool to a casing of the wellbore at a predetermined depth. The method further includes transmitting a seismic signal into the subsurface formation from a source located above the subsurface formation, receiving the seismic signal with the at least one seismic sensor, deactivating the first electromagnet to release the untethered downhole tool from the casing of the wellbore, releasing the ballast from the untethered downhole tool such that buoyancy effects move the tool uphole, and retrieving the untethered downhole tool from the wellbore.

摘要： Implementations described and claimed herein provide systems and methods for isolation detection. In one implementation, an axial acoustic signal is obtained. The axial acoustic signal is captured using an axial sensor deployed in a structure in a subterranean surface. The axial acoustic signal is separated into a first wave region and a second wave region by applying velocity filtering. An axial symmetry of a portion of the structure is determined based on at least one of the first wave region or the second wave region.

摘要： Smart wellhead assemblies with sensors for detecting positions of components within the bores of the wellhead assemblies are provided. In some instances, the sensors can be used to detect one or more of landing, locking, or concentricity of hangers, packoffs, or other internal wellhead components within bores. In one example, a method of installing a hanger within a wellhead includes lowering the hanger within the wellhead and using one or more sensors to detect when the hanger is at a target location. The method can also include activating a locking mechanism of the hanger and using the one or more sensors to detect when the locking mechanism has secured the hanger within the wellhead. Additional systems, devices, and methods are also disclosed.

摘要： Implementations described and claimed herein provide systems and methods for isolation detection. In one implementation, a radial acoustic log is obtained. The radial acoustic log is captured using a radial sensor of an acoustic logging tool deployed within a first structure. The first structure disposed within a second structure in a subterranean environment. A radial symmetry is determined using the radial acoustic log. An eccentricity of the first structure relative to the second structure is determined based on the radial symmetry.

摘要： A method that includes storing automated drilling-related workflows (“ADRWs”) in an electronic database, with each including a set of instructions to be executed by a controller so that a task is executed from beginning to end. The set of instructions include a controller selecting a drilling parameter input via one or more database look-up procedures and each of the ADRWs comprises an automation configuration. The method also includes a controller: initiating execution of an ADRW; monitoring drilling performance output during the execution of the ADRW; comparing the drilling performance output to an expected drilling performance output; and based on the comparison, automatically altering, during the execution of the automated drilling-related workflow: the instructions for the controller to select the drilling parameter input via the one or more database look-up procedures; or the automation configuration associated with the automated drilling-related workflow.

摘要： A monitoring system includes a first transducer component configured to couple to a running tool that is configured to place an insert into a housing and a second transducer component configured to couple to the housing. One of the first transducer component or the second transducer component is configured to emit acoustic waves, and the other one of the first transducer component or the second transducer component is configured to output sensor signals indicative of a received portion of the acoustic waves. The monitoring system also includes one or more processors configured to determine that the insert is in a landed position in the housing based on the sensor signals.
