Publication number: 20240044212Abstract: A downhole drilling tool, forming part of a subterranean drilling system, may include at least one plate secured to an exterior of an elongate body. Electronics may be disposed between the plate and the body to be protected by the plate while still readily accessible. A dynamic element may be radially extendable from the plate to engage an inner wall of a borehole being drilled. If this radially-extendable element becomes worn or damaged from this engagement, the plate may be replaced. More expensive components of the drilling tool may be contained within the elongate body, rather than the plate, thus reducing replacement frequency. Additionally, plates including unique features may be employed at different times without altering the underlying elongate body.Type: ApplicationFiled: October 23, 2023Publication date: February 8, 2024Inventors: Jonathan D. Marshall, Steven G. Villareal, Michael George Azar, Scott Richard Woolston
