    Abstract: An intelligent drilling system is disclosed. The intelligent drilling system includes an inner drill pipe adapted to rotate around a longitudinal axis in a transversal plane of a wellbore to advance a drill bit during a drilling operation, an external drill string shield surrounding the inner drill pipe and coupled to the inner drill pipe via at least one bearing system, the at least one bearing system adapted to decouple the external drill string shield from a rotational motion of the inner drill pipe in the transversal plane such that the external drill string shield remains substantially stationary during the drilling operation, and an in-situ sensing system disposed on an interior wall of the external drill string shield to measure at least one downhole parameter of the wellbore.

    Abstract: A downhole sub has a body defined by a wall extending in an axial direction from a first end to a second end. An inner surface of the wall defines a flow path through the downhole sub and an outer surface of the wall defines an outer diameter of the downhole sub. A compartment extends from the outer surface into the wall to having a depth less than a thickness of the wall. A housing may be removably fixed in the compartment. One or more mobile devices may be disposed in the housing. Each of the one or more mobile devices includes a sensor encapsulated in a protective material. A control element may block an opening of the housing, the control element is made of a dissolvable material configured to dissolve at a predetermined depth in a wellbore and release the one or more mobile devices into the wellbore.

    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 method for plugging a lost-circulation zone in a subsurface formation includes introducing a drillstem including a drilling stabilizer into a wellbore during drilling operations, the drilling stabilizer including at least stabilizer blades and a pressure sensor. Each stabilizer blade includes at least an inner chamber, a light source, and a window. The method further includes injecting a lost-circulation fluid, including a plurality of lost-circulation particles, into the wellbore. Each lost-circulation particle includes a lost-circulation additive encapsulated by a photo-sensitive coating. The method further includes measuring a pressure differential with the pressure sensor and providing a pressure signal to the light source of each stabilizer blade, thereby actuating the light source to produce a light beam, which allows the light beam to contact the photo-sensitive coatings of the lost-circulation particles to release the lost-circulation additives. The method further includes allowing the lost-circulation fluid to plug the lost-circulation zone.
