  • Publication number: 20240068364
    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.

  • Patent number: 9574938
    Abstract: An optical fluid analyzer tool may have an evaluation flowline which receives a flow of fluid from a geotechnical formation and may have a cleanup flowline which receives another flow of fluid from the geotechnical formation. A flow routing system may be connected to the evaluation flowline and may be connected to the cleanup flowline. The flow routing system may establish isolated flow or commingled flow for the evaluation flowline and may establish isolated flow or commingled flow for the cleanup flowline. A sample chamber may be connected to the evaluation flowline and may be connected to the cleanup flowline. A first pump module may draw the fluid from the geotechnical formation, and an optical fluid analyzer connected to the cleanup flowline and the evaluation flowline may analyze the fluid.

  • Patent number: 9097102
    Abstract: A downhole coring tool conveyable within a borehole extending into a subterranean formation, wherein the downhole coring tool comprises a housing, a hollow coring bit extendable from the housing, a first motor operable to rotate the coring bit, and a second motor operable to extend the coring bit into the subterranean formation through a sidewall of the borehole in a direction not substantially parallel to a longitudinal axis of the borehole proximate the downhole coring tool. A static sleeve disposed in but rotationally independent of the coring bit receives a portion of a core sample of the formation resulting from extension of the coring bit into the formation. The static sleeve comprises a protrusion extending radially inward toward the core sample sufficiently to mark the core sample.

  • Patent number: 8544553
    Abstract: An apparatus and a method to seal and prevent leakage within a downhole tool are disclosed herein. The apparatus includes a first body portion having a first fluid flow path formed therethrough and a second body portion having a second fluid flow path formed therethrough. The second body portion is movable between a first position and a second position with respect to the first body portion. The apparatus further includes a stopper connected to the second body portion and disposed within the first body portion. When the second body portion is in the first position, the stopper sealingly engages the first fluid flow path, and when the second body portion is in the second position, the stopper sealingly disengages from the first fluid flow path.
