Abstract: Systems and methods presented herein include sidewall coring tool assemblies used to return core plugs of rock from a sidewall of a wellbore as part of a data collection exercise for exploration and production of hydrocarbons. A coring bit and a coring shaft of the present disclosure allow space for cuttings to move away from the bit face when drilling into a formation. In addition, certain embodiments include a plurality of inlets disposed circumferentially on an external surface at a first axial end of the coring shaft, a plurality of internal grooves disposed on an internal surface of the coring shaft, and/or a plurality of fins disposed on the external surface to direct flow of drilling and debris away from the coring bit. In addition to providing more space for cuttings to move away from the coring bit, the torque needed to drive the bit is lessened as the surface area of the bit contacting or engaging the formation is reduced.

Abstract: A tool for use in a borehole in a geological formation may include a chassis, a drill collar surrounding the chassis, a port plug coupled between the drill collar and the chassis, RF antennas carried by the drill collar, and a multi-chip module (MCM) electronics package(s). The electronics package(s) may include a hermetically sealed electronics housing positioned between the chassis and the drill collar, a substrate within the electronics housing, RF transmitter circuitry on the substrate to cooperate with at least one first RF antenna to transmit RF signals into the geological formation, and RF receiver circuitry on the substrate to cooperate with at least one second RF antenna to receive RF signals from the geological formation. Furthermore, an electronics housing mount may couple the electronics housing with the port plug, and the electronics housing mount may have a passageway extending therethrough for receiving the port plug.
