Abstract: A drilling system includes an internal assembly comprising a chassis, a flow diverter, or both, and a strain gauge coupled to the chassis, the flow diverter, or both, in which the strain gauge is configured to output a signal associated with a strain deformation of the internal assembly. The drilling system also includes a drill collar coupled to the internal assembly, in which the internal assembly extends along the drill collar, and the drill collar encloses the internal assembly of the internal assembly such that a strain deformation of the drill collar causes the strain deformation of the internal assembly.

Abstract: A cutting element assembly includes a cutter support including a cutter bore. A cutting element is in the cutter bore and a resilient element is integral with the cutter support. The resilient element is longitudinally compressible and has a displacement of greater than 0.1 mm and optionally less than 2 mm. Another cutting assembly includes a cutter support coupled to multiple cutting elements. A resilient element of the cutter support is compressible based on a force applied to the cutter support through one or more of the cutting elements. The resilient element can include a slit in the cutter support. A slit may, for instance, extend perpendicular or transverse to an axis of the cutting elements and allow the cutter support to flex and close off or reduce a size of the slit when forces act on one or more of the cutting elements.

Abstract: A method of identifying a geothermal reservoir of an earth formation comprises receiving engagement data from an engagement sensor. The engagement data corresponds to an engagement of the instrumented engagement element with a borehole in the earth formation. The method includes identifying environment data from a rotation sensor. The environment data corresponds to a downhole environment of the engagement data. The method includes mapping the engagement data to the environment data to generate mapped engagement data.

Abstract: In a drill bit which has hard-faced cutting or gauge protection elements positioned to be in direct contact with subterranean formation as the bit is rotated, at least one of these elements includes a window positioned to be in direct contact with the formation or cuttings from the formation as the bit rotates and moves forward to drill into the formation. Electromagnetic radiation with wavelength in the range from 100 nm to 2600 nm is transmitted through the window to the formation in contact with the window. Electromagnetic radiation such as fluorescence that returns through the same window is received by a spectrometer. The source and receiver of electromagnetic radiation are both accommodated within the downhole drilling equipment but spaced from the windowed element. The electromagnetic radiation travels along light guides from the source to the window and from the window to the receiver.

Abstract: Methods for drilling a wellbore into a subterranean formation include preparing a drilling fluid and circulating the drilling fluid in the wellbore while drilling in the subterranean formation, forming a filtercake from the drilling fluid, creating or encountering one or more fractures in the subterranean formation while drilling, and allowing a portion of the filtercake formed to at least partially seal the one or more fractures while continuing the drilling.
