摘要： The disclosure provides a drill bit including a bit body and a blade extending form the bit body. The blade includes a first element protruding from a surface of the blade and a second element protruding from the surface of the blade. The first element and the second element are each configured to extend or retract relative to the surface of the blade and are coupled to each other such that when the second element retracts relative to the surface of the blade, the first element extends relative to the surface of the blade. The first element is disposed within a first pocket formed in the surface of the blade, and the second element is disposed within a second pocket formed in the surface of the blade. A communication channel is formed between the first pocket and the second pocket.

摘要： Downhole neutron generators, downhole logging tools that utilize neutron generators, and methods to auto tune downhole neutron generators are disclosed. While a neutron generator is deployed in a borehole of a wellbore, the method includes determining whether an oscillation cycle of an ion beam current generated by the neutron generator is stable. After a determination that the oscillation cycle of the ion beam current is stable, the method includes determining proportional, integral, and derivative parameters of a proportional-integral-derivative controller that is operable to adjust an amount of power supplied to generate ions. The method further includes adjusting a replenish voltage of a replenish power supply of the neutron generator based on the proportional, integral, and derivative parameters.

摘要： Systems and methods of the present disclosure generally relate to correcting isotope ratio calculations during wellbore operation. A method for correcting isotope ratios during a wellbore operation, comprising: receiving a flow-in fluid sample from a wellbore; receiving a flow-out fluid sample from the wellbore; passing each sample to an analytical instrument operable to determine isotopes in each fluid sample; outputting a signal intensity or signa area: assigning a depth to the signal intensity or the signal area; and determining a corrected isotope ratio by subtracting a signal for the flow-in fluid sample from a signal for the flow-out fluid sample.

摘要： A system is provided including a coiled tubing reel apparatus including a reel drum for storing a coiled tubing string spooled on the reel drum and a hydraulic reel drive motor that controls rotation of the reel drum. The system further includes a reel controller that determines an estimated reel back tension for a portion of the coiled tubing string between the reel apparatus and the injector based on a set of parameters related to a coiled tubing operation. The reel controller determines a target reel back tension to be applied to the portion of the coiled tubing string by adjusting the estimated reel back tension based on a historical job dataset. The reel controller then determines and sets a target hydraulic pressure of the reel drive motor to achieve the target reel back tension in the portion of the coiled tubing string.

摘要： Methods to operate an NMR tool, methods to simulate a numerically-controlled oscillator of an NMR tool in real time, and downhole NMR tools are presented. A method to operate an NMR tool includes determining a phase shift of a sinusoidal wave, determining a number of look-up tables and a number of terms of Taylor Expansions performed to obtain a value corresponding to a phase angle of the phase shift, and separating the phase angle into a first component and a second component. The method also includes obtaining a first value corresponding to the first component from the number of look-up tables, performing the number of terms of Taylor Expansions on the second component to obtain a second value corresponding to the second component, combining the first value and the second value to obtain the value of the phase angle, and generating the sinusoidal wave having the phase shift.
