A well logging instrument deployment device according to this aspect of the invention includes a housing configured to be coupled to a pipe string. A latch disposed in the housing and is configured to retain a well logging instrument in a first longitudinal position inside the pipe string. An actuator is configured to release the latch to enable longitudinal movement of the well logging instrument inside the pipe string. A signal detector is operatively coupled to the actuator and is the configured to detect a command signal for operating the actuator.

Method and apparatus for pipe-conveyed well logging

A wireline configurable well logging instrument is connected to a drill pipe carrier and movable from a retracted position to an extended position. The drill pipe carrier is positioned on a pipe string that may comprise a portion of wired pipes communicatively coupled at each joint. Communication between the drill pipe carrier and the well logging instrument includes the use of inductive couplers, wires and combinations thereof.

System and method for communicating between a drill string and a logging instrument

An apparatus, a system and a method for motion compensation use wired drill pipe to transmit downhole measurements from downhole tools to the surface. The wired drill pipe may transmit control signals from a terminal located at the surface to the downhole tools. In response to the control signals, a motion compensation component may enable the drill string to compensate for motion, such as, for example, heave. The motion compensation component may change a length of the drill string. A downhole tool having arms may be connected to the drill string and the wired drill pipe. The control signals may direct the downhole tool to move between an extended position and a retracted position.

A wellbore instrument system includes a pipe string extending from earth's surface to a selected depth in a wellbore. The pipe string includes at least one of an electrical conductor and an optical fiber signal channel. A power sub including an electric power source is coupled proximate a lower end of the pipe string. At least one electrically powered wireline configurable wellbore instrument is coupled to the power source in the sub.

Power systems for wireline well service using wired pipe string

A coiled tubing connection system is used in a well. A connector having an engagement end is used to couple a wellbore device to the end of a coiled tubing. The connector is spoolable, and the engagement end comprises engagement features that facilitate formation of a connection that is dependable and less susceptible to separation.

System and method for forming a coiled tubing connection

A wellbore instrument system includes a pipe string extending from earth's surface into a wellbore. The pipe string includes at least one of an electrical conductor and an optical fiber signal communication channel. A power sub is coupled to at least one wireline configurable wellbore instrument. The power sub is also coupled to the pipe string. The instrument is configured to receive electrical power from the power sub. The instrument includes at least one sensor responsive to at least one of movement of the instrument, change in a instrument operating condition and an environmental condition proximate the instrument. The sensor is configured to transmit signals therefrom over the communication channel.

A pipe conveyed well logging assembly is provided that includes a pipe string; a carrier assembly connected to the pipe string; and a memory logging tool carried by the carrier assembly and movable from a removably latched retracted position, protected within the carrier assembly, to a removably latched extended position, at least partially protruding from a lower end of the carrier assembly.

Latchable carrier assembly for pipe conveyed well logging

A pipe conveyed well logging assembly is provided that includes a pipe string; a carrier assembly connected to the pipe string and having an inner housing and an outer housing; and a memory logging tool carried by the carrier assembly and movable from a retracted position, protected within the inner housing; and an extended position, at least partially protruding from a lower end of the carrier assembly.

Carrier assembly for a pipe conveyed well logging assembly

A method of performing a pipe conveyed well logging operation is provided that includes providing a pipe conveyed well logging assembly having a pipe string, a memory logging tool and a memory module; deploying the assembly into a wellbore; operating the memory logging tool to perform a logging operation to obtain logging data from the wellbore; and retrieving the obtained logging data prior to withdrawing the pipe string from the wellbore.

Methods of retrieving data from a pipe conveyed well logging assembly

A well completion method performed in a single trip into a well includes inserting a service tool into the well to a desired location; gravel packing the well; and circulating fluids within the wellbore through the service tool to dislodge and remove filter cake residue. A method of completing a subterranean well performed in a single trip into a wellbore includes running a service tool into the well, the service tool defining multiple, selectable flow paths; gravel packing the well; selecting a different flow path of the service tool; removing a filter cake from the wellbore by circulating a fluid through the service tool; spotting specially fluids within the wellbore at desired locations; and removing the service string from the well.

Circulation tool for use in gravel packing of wellbores

A circulation tool includes a housing having a longitudinal bore therethrough, a wall, and at least one lateral port through the housing wall and at least two sliding sleeves. At least one circulation flow passage is disposed within the housing wall. A plurality of circulation paths are created by the selective positioning of the at least two sliding sleeves.

A full bore set down tool assembly provides a housing attached to a packer in a wellbore and aligned with the production zone. A service tool of the tool assembly is attached to a tubing string extending to the surface and is adapted for selective, removable attachment to and positioning within the housing. The tool assembly defines a downstream flow path and a return flow path when the service tool is attached to the housing. A ball valve that is selectively shiftable from the surface opens and closes the return flow path to define a circulate position and a squeeze position. The housing, service tool, and ball valve also define a reverse position. The tool assembly facilitates gravel packing of the annulus between the wellbore casing and the service string including the tool assembly.

A system for isolating a production pipeline string from the flow of fluids includes an isolation pipe string assembly. The isolation pipe string assembly is positioned by a shifting collet assembly so that in a first position fluids are allowed to the well bore through a sand control production screen. The shifting collet assembly is then used to position the isolation pipe string assembly in a second position wherein seals are placed both above and below the sand control production screen so that fluids are not allowed to re-enter the well bore.
