Abstract: Systems and methods presented herein include sidewall coring tools used to return core samples of rock from a sidewall of a wellbore as part of a data collection exercise for exploration and production of hydrocarbons. In particular, the systems and methods presented herein perform sidewall coring of a subterranean formation using a combination of rotary and percussive coring. More specifically, the systems and methods presented herein rotate a coring cylinder of a sidewall coring tool back and forth less than a full rotation while pushing the coring cylinder of the sidewall coring tool against a bore wall of a wellbore, and push the coring cylinder of the sidewall coring tool into the subterranean formation to enable extraction of a core sample of the subterranean formation.

Abstract: The systems and methods presented herein include a sidewall coring tool assembly that includes a coring shaft having an internal cavity and configured to be coupled to a coring motor shaft of a coring motor at a first axial end of the coring shaft. The coring shaft includes a plurality of scoops disposed circumferentially on a first external surface of the coring shaft. Each scoop of the plurality of scoops forms a conduit from an exterior of the coring shaft to an interior of the coring shaft. The sidewall coring tool assembly also includes a coring bit coupled to the coring shaft at a second axial end of the coring shaft. The sidewall coring tool assembly further includes a static sleeve coupled to the coring motor and disposed radially within the internal cavity of the coring shaft.

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.
