Abstract: The present invention provides methods and apparatus for expanding a first, smaller diameter tubular into frictional contact with a second, larger diameter tubular or wellbore. In an embodiment, annular formations formed on an inner surface of a split ring (120) engage an outer surface of the smaller tubular. In one aspect, the smaller diameter tubular is provided with an annular recess there around, the annular recess including recessed grooves formed there around. Therefore, the split ring is disposable within the annular recess and the annular formations formed on the split ring are constructed and arranged to fit within the recessed grooves of the annular recess of the tubular. An outer surface of the split ring is provided with teeth (130) or some other grip-enhancing material or formation. The split ring also includes a split portion (140) permitting the ring to expand in diameter as that portion of the tubular is expanded in diameter.

Abstract: The present invention provides a pipe-handling machine (100) for picking up and laying down pipe, such as at a rig site. The machine first comprises three elongated and nested truss members. First, a trestle (200) is provided; second, a trough carrier (300) is received within the trestle; and third, a trough (400) is slidably received within the trough carrier. The machine next comprises an inclined ramp (500). A lower end of the ramp is pivotally connected to the trestle, while an upper end of the ramp extends upward to the rig floor. The length of the ramp is adjustable to accommodate rig floors of varying heights. A trestle transport mechanism (550) selectively moves a front end of the trestle upwards along the ramp, thereby delivering a joint of pipe to the rig floor. The trough may optionally be moved along the trough carrier and out over the rig floor to aid in delivery. Features (310) may optionally be incorporated to reduce the angle of approach of the joint of pipe relative to the rig floor after the trestle transport mechanism is actuated.

Abstract translation: 本发明提供一种用于拾取和铺设管道的管道处理机器（100），例如在钻机现场。 机器首先包括三个细长和嵌套的桁架构件。 首先，提供一个支架（200）; 第二，槽支架（300）被收纳在支架内; 并且第三，槽（400）可滑动地容纳在槽载体内。 该机器接下来包括斜坡（500）。 斜坡的下端枢转地连接到支架上，而斜坡的上端向上延伸到钻机底板。 坡道的长度可调，以适应不同高度的钻台。 托架运输机构（550）选择性地沿着斜坡向上移动托架的前端，从而将管道的接头输送到钻机底板。 槽可以可选地沿着槽载体移动并且在钻台底部上移动以帮助输送。 特征（310）可以可选地被结合以减小在支架传送机构被致动之后管道相对于钻台的接头的接近角度。

Abstract: Methods, apparatus and articles of manufacture are provided for a configurable downhole tool (100). The downhole tool (100) includes a plurality of devices (112 1, 112 2, ..., 112n) each of which is configured for one or more functions. At some point during operation (e.g., during system initialization), the presence of each device disposed on the downhole tool is detected. Each device may then begin performing its respective function or functions. For example, some devices (112 1, 112 2, ..., 112n) may be configured to collect environmental data while the tool is disposed in a wellbore. In one embodiment, the collected data is provided to a transceiver. The transceiver (339) then transmits the data from the downhole tool to some remote receiving unit (120), which may be located at the surface of the wellbore.

Abstract: An apparatus and method for expanding a lower string of casing into frictional contact with an upper string of casing, and thereby hanging the lower string of casing onto the upper string of casing is provided. The apparatus essentially defines a lower string of casing having a separation region formed in the top end thereof. The lower string of casing is run into the wellbore, and positioned so that the top end overlaps with the bottom end of an upper string of casing already cemented into the wellbore. The top end of the lower casing string is expanded below the depth of the separation region into frictional contact with the upper string of casing. At the same time, or shortly thereafter, the top end of the upper string of casing is expanded. As the portion of the lower casing string having the separation region is expanded, the casing severs into upper and lower portions. The upper portion can then be removed from the wellbore, leaving a lower string of casing expanded into physical contact with an upper string of casing. The separation region may be formed by heat treating the tubular at the point of desired severance. In another aspect, the separation region may comprise the connection between two tubulars. This involves connecting two tubulars to form the tubular to be expanded downhole. The tubular formed is then lowered into the wellbore and expanded at the connection to separate the tubular.

Abstract: The present invention generally relates to a flow-actuated valve for use in a wellbore. The invention includes a body having a closing member (127) and a seat (109). The closing member and seat are separable to open and close the valve, thereby allowing the flow of fluid through the valve. The invention further includes a retainer (205) to initially retain the valve in the open position absent a predetermined fluid flow rate in a first direction for a predetermined time period. A biasing member (140) thereafter urges the valve to the closed position, absent another fluid flow rate in the first direction.

Abstract: The present invention provides an expandable tubular having improved polished bore receptacle protection. The present invention further provides methods for completing a wellbore through the use of an expandable string of casing having improved polished bore receptacle protection. In one aspect, the invention includes a liner member (200) having an expandable section (225), and a polished bore receptacle (25) positioned below the expandable section. The expandable section is run into a wellbore (205), and is positioned to overlap with the bottom portion of a string of casing (210) already set within the wellbore. The expandable section is then expanded into frictional engagement with the surrounding casing. The expandable section optionally includes at least one sealing member (260) and at least one slip member (270) on the outer surface. In one aspect, a transition section (275) is provided between the expandable section and the polished bore receptacle. The transition section defines a sloped inner diameter which provides further protection for the sealing surfaces of the polished bore receptacle as tools, fluid, and tubulars are transited downhole through the polished bore receptacle.
