摘要： A whipstock (1) comprises a concave (2) which comprises a tapered support member (3) which accommodates a plurality of spacers (7). The spacers (7) can be moved from an inoperative position to an operative position in which they project outwardly from the tapered support member (3) to support the tapered support member (3). The spacers (7) are shaped and disposed so that when they are moved to project outwardly from the support member (3) they project by different distances from the support member (3).

摘要： A tool (1) for obtaining rock samples during drilling, comprising a hole opener assembly or underreamer (2) for attachment to a drill string with a coring assembly (3) mounted in a recess in the body of the tool (1). The coring assembly (3) is mounted on the tool body (1) so that it can pivot (5) and be deployed at a shallow angle to the longitudinal axis of the tool body (1). The hole opener assembly or underreamer (2) forms a ledge around the tool body (1) and the coring assembly (3) performs a coring operation on the ledge. Alternatively, the coring assembly (13) performs a coring operation in the pocket formed by an underreamer (12) where the coring assembly (13) is mounted within a cutting arm (12a) of the underreamer (12).

摘要： A disclosed effective porosity determination method for tight gas formations includes: obtaining a core sample sealed in a pressure-maintaining core vault during transport out of the borehole; coupling the core vault to a collection chamber; based at least in part on measured pressure, temperature, and fluid volumes in the collection chamber, deriving the number of moles of gas retrieved with the core sample; and combining the number of moles with a downhole pressure, a downhole temperature, and a downhole core sample volume to determine an effective porosity of the tight gas formation. A system embodiment includes: a coring tool having a core vault with a seal to provide pressure-preserved transport of a core sample from a tight gas formation; a collection chamber that attaches to the core vault to measure volumes of fluids and gas; and a processing unit that responsively determines an effective porosity of the tight gas formation.
