    摘要: An apparatus for providing pressure to a sample. The apparatus comprises a housing having a cavity, an elastomer within the cavity, and a means for providing pressure to the elastomer within the cavity. The housing and the elastomer are configured to allow a sample to be inserted into the cavity, such that the sample is surrounded by the elastomer and such that the elastomer and the sample together fill the cavity.

    摘要: An apparatus to simulate fluid loss through vugs in formations includes a housing defining an inner volume, and having a first end and a second end. The inner volume represents an inner region of a wellbore formed in a formation containing a vugular loss zone. The housing can receive wellbore fluid within the inner volume. A first cover late, which sealingly covers the first end, represents a first volumetric boundary of the inner region of the wellbore. A second cover plate, which sealingly covers the second end, represents a second volumetric boundary of the inner region of the wellbore. An outlet in the second cover plate can be switched between open and closed states. The outlet in the open state represents a vug in the inner wall of the wellbore. The apparatus includes a pressure port configured to transmit fluidic pressure in a direction of gravity within the inner volume and to apply the fluidic pressure to the wellbore fluid within the inner volume.

    摘要: A weld test plug has a flange; an actuator rod mounted to the flange, the actuator rod having: a part expander; an annular seal; and an axial stop; in which the actuator rod is connected to, during use, cause the part expander to actuate: the axial stop to move in a radially outward direction relative to the actuator rod; and the annular seal to radially expand and abut the axial stop. A method includes inserting an actuator rod into an open end of a vessel, the actuator rod carrying an annular seal, and an axial stop; sealing the open end of the vessel around the actuator rod; operating the actuator rod to actuate: the axial stop to move in a radially outward direction relative to the actuator rod; and the annular seal to radially expand to abut the axial stop and seal against an inner circumferential surface of the vessel.
