摘要： Some examples described herein relate to generating a non-fungible token on a distributed ledger, where the non-fungible token represents a machine-learning model for use in performing hydrocarbon extraction operations. The non-fungible token can also include one or more identifiers of one or more training datasets used to train the machine-learning model.

摘要： In various wellbore test systems, a probe mechanism that is extended to contact the formation within a wellbore, and retracted to allow movement of the test system, both rotationally and longitudinally, within the wellbore. A combination including monitoring an actuation fluid pressure used to actuate the probe mechanism to extend and to retract, and the use of one or more timers, provide information used to determine the position of the probe mechanism during the extension and retraction movements.

摘要： Wellbore equipment used in oil and gas operations can be negatively affected by corrosive fluids. Coatings can be applied to the equipment to help protect the equipment. A field test can be used at a wellsite to ensure the coating is effective. Due to the HSE risks of the corrosive fluids, a proxy fluid can be used instead. The proxy fluid can have similar chemical or physical properties and simulate the corrosive fluid that is anticipated to be present in the wellbore. The wellbore equipment that is coated can be sealed to create a containment area where an initial concentration of the proxy fluid is introduced into the containment area for a period of time. A final concentration of the proxy fluid can be measured after the period of time has elapsed. By calculating the percent change of the proxy fluid, the effectiveness of the coating can be determined.

摘要： Aspects of the subject technology relate to systems and methods for optimizing telemetry schemes with a constant insensible group delay. Systems and methods are provided for receiving an acquisition including compressed data and dummy data from a downhole logging system, determining a prior decompressor queue size based on the acquisition for a plurality of time intervals, determining a decompressor data size based on the acquisition for the plurality of time intervals, and determining a delay where the prior decompressor queue size is continuously greater than or equal to the decompressor data size for the plurality of time intervals.

摘要： A body of a shear pin can be positioned in a pad stopper of a steering pad of a rotary steerable system. The rotary steerable system can be used to steer a drill in a wellbore. The steering pad can be positioned on the rotary steerable system such that a head of the shear pin is coupled with a lateral pad of the rotary steerable system. The head of the shear pin can deactivate the steering pad by preventing the steering pad from actuating. A fluid pulse can be output in the wellbore to break the shear pin for enabling the steering pad to actuate to cause the rotary steerable system to steer the drill in the wellbore.

摘要： System and methods of petrophysical modeling are disclosed. Measurements of formation parameters are received from one or more measurement tools during a first stage of a downhole operation within a reservoir formation. A correlation between each of the formation parameters and a target parameter of the formation is determined based on the measurements. One or more formation parameters are selected as input parameters for a symbolic regression model, based on the correlation. A symbolic regression model is trained to generate candidate formation models representing the target parameter, based on the selected input parameters. One or more optimizations are applied to the candidate models to determine a target petrophysical model of the formation. Values of the target parameter are estimated for at least one formation layer, based on the target petrophysical model. A second stage of the downhole operation is performed within the formation layer(s) based on the estimated values.

摘要： A downhole sample extractor includes a sample container chamber that holds a sample container containing a downhole sample. The downhole sample extractor also includes a sample extraction chamber having an internal chamber that is partially filled with a carrier solution, wherein the downhole sample is mixed with the carrier solution in the internal chamber of the extraction container. The downhole sample extractor further includes a first piston that, when actuated, inserts the sample container into the internal chamber of the sample extraction chamber.
