    Abstract: A method for actuation of a downhole device includes rotating a drill pipe relative to a cylindrical pipe disposed coaxially within the drill pipe. First segments including a first material are disposed on the inner surface of the drill pipe. Second segments including a degradable material are disposed on the outer surface of the cylindrical pipe, with each of the second segments aligned with a corresponding first segment. The first material and the degradable material are insoluble in the downhole fluid, and a solubility of the degradable material in a solvent is greater than a solubility of the first material in the solvent. The method includes generating a first electrical signal pattern during rotation of the drill pipe; introducing the solvent into the drill pipe, in which the degradable material degrades responsive to introduction of the solvent; and generating a second electrical signal pattern after introduction of the solvent.

    Abstract: A downhole device that drills a wellbore includes a stabilizer which has a body and blades. The blades are disposed on a surface of the body and each blade has a hollow space. The blades each include a dissolvable window that is disposed on a surface of each of the blades and a light source that emits light to the wellbore. The dissolvable window blocks light emitted from the light source thereby reducing or eliminating light from being transmitted to the wellbore. The dissolvable window dissolves upon exposure to a fluid containing a dissolving medium, thereby allowing the light source to transmit light to the wellbore. Methods of using the downhole device to activate downhole chemicals are also provided.

    Abstract: A testing device that includes a wear testing device, a sensor array, and a controller. The wear testing device includes a sample rotation element configured to hold and to rotate a sample; and a cutting element holder configured to hold a cutting element and to engage the cutting element with the sample as the sample rotates. The sensor array includes an acoustic emissions (AE) sensor configured to measure an acoustic signal generated during engagement between the cutting element and the sample; and a load sensor. The controller is communicably connected to the sensor array and configured to determine a toughness and a wear resistance of the cutting element using the acoustic signal, the applied load, and a wear state of the cutting element.

    Abstract: A system including one or more hardware processors for automatic evaluation of a cutting element in a wear testing device. The system includes an access module to access cutting element event analysis results from a sensor array. The system further includes a first model trained to classify a cutting element event of the cutting element according to a supervised machine learning algorithm, and output a predicted event type of the cutting element event. The system further includes a second model trained to classify a cutting element event of the cutting element according to an unsupervised machine learning algorithm, and output a predicted behavior of the cutting element event. The system further includes a controller to determine a toughness and a wear resistance of the cutting element. The system also includes an output module to generate and display a work order on a user interface of a client device.
