摘要： An elevator can include an elevator body, a set of ears on the elevator body configured for cooperative engagement with a set of bails, and another set of ears configured for cooperative engagement with another set of bails. A method of operating an elevator can include connecting a set of bails to a set of ears on an elevator body, and connecting another set of bails to another set of ears on the elevator body, the sets of bails being different from each other. A well system can include a lifting apparatus, an elevator including an elevator body, and one of two sets of bails connected between the lifting apparatus and the elevator. One set of ears on the elevator body being configured to cooperatively engage one set of bails, and another set of ears on the elevator body being configured to cooperatively engage the other set of bails.

摘要： A downhole assembly includes a tubular body having a bore and a downhole tool connected to the tubular body. The downhole assembly also includes a sensor assembly having a carrier and a sensor. A sensor adapter is used to couple the sensor assembly to the tubular body. The sensor adapter includes an adapter body disposed in the bore of the tubular body; an adapter shaft for connection with the carrier; and a plurality of channels formed between the adapter shaft and the adapter body.

摘要： A stage tool used in a wellbore has two sub-housings that couple together. A first sleeve is movably disposed in the tool and is held closed with a temporary connection relative to a side port. The first sleeve has a first seat of millable material. A second sleeve is also movably disposed in the tool and is held open with a temporary connection relative to the side port. The second sleeve has a second seat of millable material. An opening plug lands on the first seat so pressure can break the connection and shift the first sleeve open relative to the side port. After pumping cement out of the tool, a closing plug pumped to the second seat allows pressure to break the connection and shift the second sleeve closed. The first sleeve includes a bypass that allows for fluid to pass beyond the seated plug.

摘要： A catcher for use in a wellbore includes a housing and an insert disposed within the housing. A method of using the catcher includes disintegrating at least a portion of the insert while the insert is held rotationally stationary with respect to the housing by a taper connection between the insert and the housing.

摘要： A bottom hole assembly can include a mill and a whipstock having an upper end and an opening. A retractable pin extends from the mill into the opening. A section of the whipstock is separable from the whipstock in response to a force applied to the mill. The section is positioned between the opening and the upper end. A method can include positioning a bottom hole assembly in a well, the bottom hole assembly including a whipstock releasably secured to a mill, and then releasing the mill from the whipstock by separating a section of the whipstock from a remainder of the whipstock. Another method can include conveying a bottom hole assembly into a well, setting an anchor, then applying pressure to a hydraulic release mechanism, and then applying a force to the mill, thereby separating a section of the whipstock from a remainder of the whipstock.

摘要： A packer assembly includes a mandrel and a packing element disposed about the mandrel. Upper and lower recovery sleeves are disposed about the mandrel and extend between the mandrel and respective upper and lower ends of the packing element. The upper and lower recovery sleeves each have a recovery profile embedded within the packing element. Upper and lower backup assemblies are movably disposed about the respective upper and lower recovery sleeves, adjacent to the respective upper and lower ends of the packing element. The packer assembly includes at least one release mechanism. When setting the packer assembly in a bore, the packing element is axially compressed between the upper and lower backup assemblies to contact the bore wall, and the upper and lower backup assemblies splay outwards. Upon release, the packing element and backup assemblies retract, thereby facilitating retrieval of the packer assembly from the bore.

摘要： A stage cementing system (20) includes a stage cementing assembly (22) having a stage tool (24). The stage tool has an outer mandrel (62), an inner mandrel (64) coupled to and disposed inside of the outer mandrel, an annular chamber (66) between the outer mandrel and the inner mandrel, a first outer port (74) through the outer mandrel, and longitudinally spaced first (68) and second (70) inner ports through the inner mandrel. The stage cementing system further includes an inner string assembly (40) configured to be located inside the inner mandrel. The inner string assembly has a tubular body (104) including a central throughbore (106) and longitudinally spaced first (140) and second (156) side ports, a lower external seal element (120) below the first and second side ports, a middle external seal element (118) between the first and second side ports, and an upper external seal element (116) above the first and second side ports..

摘要： A gravel pack assembly for a borehole has first and second joints and a foil. The basepipes of the joints connect end-to-end, and both of the basepipes having filters for filtering fluid passage from a borehole into bores of the basepipes. Transport tubes are disposed along the first and second joint, and a jumper tube expands across the connected ends of the basepipes and connects the transport tubes together. The foil encloses an area across the connected ends. The foil has an external surface defining an annulus thereabout with the borehole. The foil has end rings abutting the filters of the joints. At least a section of the foil leaks fluid from the borehole to the area enclosed by the foil, and at least a filter portion of the assembly filters the leaked fluid from the area to at least one of the first and second bores.

摘要： A setting tool can include a hydraulic setting mechanism that actuates in response to a level of a pressure differential between a central flow passage and an exterior of the setting tool, and a check valve assembly that permits flow between sections of the central flow passage in one direction but prevents flow in an opposite direction. One of the sections is in fluid communication with an exterior of the setting tool. A method of setting a well tool can include deploying the well tool and a setting tool into a well, and applying a pressure differential across a check valve assembly of the setting tool, thereby setting the well tool. In the deploying step, the setting tool includes the check valve assembly.

摘要： A spider for handling/gripping well components of various sizes can include multiple slip assemblies distributed circumferentially about a central axis, each slip assembly including a slip carrier radially displaceable relative to the central axis, a slip displaceable relative to the slip carrier, and a slip actuator operable to displace the slip relative to the slip carrier, the slip actuator being disposed at least partially internal to the slip carrier. Each slip assembly may include a slip carrier actuator that radially displaces the slip carrier. A table assembly may mount to a well rig with an upper surface of the table assembly being flush with a rig floor of the well rig. Another spider can include a pipe guide assembly with multiple guides and guide actuators. Each guide actuator rotates a respective one of the pipe guides about a respective guide axis that is parallel to the central axis.
