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 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: A service tool that may be inserted into a tubular, the service tool includes an anchoring system. The anchoring system includes a body having a first end, a second end, and an opening extending along a portion of the body between the first end and the second end and a gripping assembly housed within and coupled to the body. The gripping assembly may anchor at least a portion of the service tool to the tubular, and the gripping assembly includes a plurality of anchor arms disposed within the opening and that may move relative to the body. The anchoring system also includes an actuator disposed within a central bore of the body and coupled to the gripping assembly. The actuator may apply a first axial input force in a first direction and a second axial input force in a second direction opposite the first direction to the gripping assembly, At least a portion of the gripping assembly translocates relative to the body in the first direction in response to the first axial input force to position the plurality of anchor arms in a radially expanded anchoring configuration, and the portion of the gripping assembly translocates relative to the body in the second direction in response to the second axial input force to position the plurality of anchor arms in a radially contracted configuration.

Abstract: Methods and systems for evaluating the subterranean formation of a wellbore are provided. In one embodiment, a geographical orientation of a downhole tool relative to Earth may be determined. The downhole tool may include a coring tool positioned to extract a core sample from a formation of the Earth. The orientation of the core sample with respect to the downhole tool also may be determined. Further, based on the geographical orientation of the downhole tool and the orientation of the coring sample, a geographical orientation of the core sample with respect to the Earth may be determined.

Abstract: Methods comprising conveying a downhole tool within a wellbore penetrating a subterranean formation, wherein the downhole tool comprises a first pump and a second pump, and wherein at least one operational capability of the first and second pumps is substantially different. A fracture is initiated in the subterranean formation by pumping fluid into the formation using the first pump. The fracture is propagated in the subterranean formation by pumping fluid into the formation using the second pump.
