摘要： Systems and methods of the present disclosure relate to control of a downhole tool via at least one radio isotope. The radio isotope(s) is pumped from the surface to contact an isotopic analyzer of the tool. The isotopic analyzer reads the isotope and directs the tool to perform a specific action(s) in the wellbore based on the type of isotope read by the analyzer.

摘要： An untethered device includes a housing, a chamber wall extending from the housing and defining a buoyancy chamber, and a discharge door. The discharge door is configured to be placed in a closed position that isolates a ballast weight within the buoyancy chamber and an open position that allows a release of the ballast weight from the untethered device to reduce a bulk density of the untethered device.

摘要： A method for optimizing drilling performance of a drilling operation is discloses. The method includes determining, while advancing a drill bit during the drilling operation based on drilling parameters specified by a user, a rate of penetration (ROP), acquiring, using sensors disposed throughout a rig of a well, sensor measurement data related to circulation of drilling fluid, generating, using a drilling hydraulics model based on at least the sensor measurement data of the circulation of drilling fluid, modeled rig and bit hydraulics data, displaying, on a driller console of the rig, the modeled rig and bit hydraulics data as a real-time drilling hydraulics profile, in response to a user viewing the displayed real-time drilling hydraulics profile, receiving an adjustment to the drilling parameters from the user, and further performing the drilling operation based on the adjustment to optimize the ROP.

摘要： Systems and methods for instructing a device within a wellbore of a subterranean well includes a drill string with an actuator assembly extending into the subterranean. The actuator assembly has a first pipe member with a segment formed of a first material. A second pipe member is coaxially aligned with the first pipe member. A plurality of bearings are positioned between the first pipe member and the second pipe member. Each of the plurality of bearings includes a second material. The first material is reactive to the second material. Certain of the plurality of bearings are changeable bearings that include a dissolvable material. The actuator assembly is operable to instruct an operation of the device by generating an instruction signal by rotating the first pipe member relative to the second pipe member and interpreting a pattern of a reaction of the segment as a bearing rotates past the segment.

摘要： A system can flush a drilling fluid sample with a hydrocarbon blend, which includes a determined concentration of at least one chemical species to generate a flushed drilling fluid sample. The system can extract a dissolved gas from the flushed drilling fluid sample. The system can determine a concentration over time of at least one chemical species of the dissolved gas. The system can generate an area per concentration curve based on the concentration over time of the at least one chemical species. The system can determine at least one concentration value of the at least one chemical species. The system can modify the at least one concentration value based on the area per concentration curve. The system can then correct bias caused by the gas extractor and fluid sampling system.

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.
