摘要： The invention relates to methods of determining whether a wellbore sealing operation has been performed correctly, and to wellbore-lining tubing which facilitates the determination of whether a wellbore sealing operation has been performed correctly. The invention has a utility in determining whether cement has been correctly supplied into an annular region defined between an internal wall of a wellbore and an external surface of a wellbore-lining tubing located in the wellbore, or whether a packer has been properly set to seal such an annular region. One disclosed method comprises the steps of: locating a wellbore-lining tubing (140) in a wellbore (100), said tubing having at least one pressure sensor (80); performing a wellbore sealing operation in an annular region (178) defined between an external surface of said tubing and an internal surface (130) of a wall of the wellbore, or between an external surface of said tubing and an internal surface of another wellbore-lining tubing (118) in which said tubing is located, to seal said tubing in the wellbore; monitoring the pressure of fluid in the annular region using the at least one pressure sensor; and recovering data concerning the pressure of the fluid monitored by the sensor to surface, the pressure data indicating whether the wellbore sealing operation has been performed correctly.

摘要： A whipstock comprises a longitudinal axis, a first end and a second end, and a tapering deflection section extending at least part of the way between the first end and the second end. The deflection section has a rear face. The deflection section has a front face, which in use will deflect a milling arrangement in a direction having a component which is perpendicular to the longitudinal axis of the whipstock. The front face has first and second side edges and a width defined between the first and second side edges. A depth of the deflection section is defined as a distance between the rear face and the front face. At at least one point along the length of the deflection surface, the depth of the deflection section at a distance from the first side edge is greater than the depth of the deflection section at the same distance from the second side edge.

摘要： Bypass valve comprising a ported housing (1) and concentrical ported sleeve (2). Ported piston (3) is slidably arranged within the sleeve. Between sleeve and piston is a control system consisting of control element (5) fixed to sleeve (2) by means of plugs (7) passing through apertures (49) and holes (68). Noses (35) protrude into recesses (34) of drive element (4). Saw teeth (31) on drive element (4) interact with teeth (29) on rotatable timing element (6). Key (27) on element (6) interacts with teeth (32) on control element (5). Lower end (70) of key is abutting against ridge (67) formed on inner surface of sleeve (2). when key (27) is engaged to teeth (32), teeth (31, 29) on elements (4, 6) are misaligned. Pressure increase results in piston (3) and drive element (4) moving downward freeing key (27) from engagement with teeth (32). Teeth (31, 29) are forced into alignment with subsequent rotation of timing element (6). In this position, ports on piston and sleeve are partially aligned. Pressure decrease results in element (6) moving up key (27) moving to next notch of teeth (32). When key (29) coincides with slot (50), piston (3) moves further down, partially occluding piston ports. When key (27) coincides with slot (52) piston (3) moves even further down totally occluding piston ports.

摘要： A whipstock assembly for milling an aperture in a casing of an oil, gas or water well, the whipstock assembly having a whipstock with a deflection face (6) for deflecting a milling head of a milling device to cut through the casing. The whipstock has a plateau portion (7) raised above the plane of the deflection face to support the milling head as it engages the casing. The plateau can induce the milling device to pivot around one of the milling heads during some of the milling operations, which optimizes the stress applied to the heads of the milling device.

摘要： A downhole swivel joint assembly comprising an upper component and a lower component. The components may assume either of two stable positions relative to each other, namely an unactivated configuration in which the components are rotationally fast with each other by virtue of the inter-engagement of splines of the lower component with splines of the upper component and an activated configuration in which the respective splines are disengaged so that the upper and lower components can rotate relative to each other. In the activated configuration the upper component is supported relative to the lower component on a ball bearing pack. Movement of the components between the activated and unactivated configurations is controlled by a resiliently deformable latch member which is C-shaped in transverse cross-section. The latch member has an internal profile which co-operates with an external profile provided on the upper component mandrel to allow the upper and lower components to snap between the activated and unactivated configurations.

摘要： A downhole releasable swivel joint comprises a mandrel and a housing. A resilently deformable retaining device maintains the components in the illustrated first relative axial position until downward movement of the housing is stopped and a sufficient load is applied to the mandrel to overcome the retaining force of the retaining device whereupon the mandrel is able to move downwardly relative to the housing to adopt a second relative axial position. Apertures are provided in the wall of the mandrel and apertures are provided in the wall of the housing. When the mandrel is in the illustrated first relative axial position the apertures and are isolated from each other by a seal. When the mandrel is in the second relative axial position the apertures communicate with each other to permit flow from the interior of the mandrel to the exterior of the housing.
