Description
METHODS FOR NAVIGATING AND FOR POSITIONING DEVICES IN A BOREHOIE SYSTEM
BACKGROUND
[0001] In the hydrocarbon recovery industry, like other industries, maximum efficiency and gain for minimum input is an ever present goal. Some of the areas in which efficiency could be improved in the hydrocarbon industry is in navigating the increasingly complex multilateral wellbore environment and in placing downhole devices in desired positions and orientations relative to the boreholes. Current technology employs many different means for locating and orienting devices and often employs multiple runs to ensure proper placement. As will be appreciated this means rig time, equipment usage, personnel, etc. and is therefore costly. [0002] Beyond cost there is also a lack of certainty about where a tool is in a labyrinth of multilateral boreholes for a longer period of time than would be desirable. [0003] It would benefit the art to reduce rig time, increase certainty and accuracy of device placements and reduce costs of well completion or re-entry.
SUMMARY
[0004] Disclosed herein is a method for navigating a wellbore including running a string into the wellbore. The string includes an orientation measurement device and an operationally associated telemetry device wherein the string is configured to allow through passage of well equipment. The method includes gathering orientation data with the orientation measurement device and telemetering the data to a remote location.
[0005] Further disclosed herein is a method for positioning a junction. The method includes running a string having a junction mounted thereon and having an orientation measurement device and a telemetry device mounted thereon wherein the string is configured to allow through passage of well equipment. The method includes gathering data regarding orientation of the junction as the junction nears a selected depth and installing the junction.
[0006] Further disclosed herein is a method for running, setting and cementing a well structure including running the well structure into a borehole on a string including an orientation measurement device configured to allow through passage of
well equipment and a telemetry device in operable communication with the orientation measurement device. The method further includes gathering data on orientation of the orientation measurement device, which data is correlated to orientation of the well structure, telemetering the data to a remote location and setting the well structure in a desired orientation.
[0007] Further disclosed herein is a running string including a length of tubing, wherein an orientation measurement device and telemetry device is in operable communication with the tubing, the string being configured to allow through passage of well equipment.

DETAILED DESCRIPTION
[0019] In a first embodiment of the method disclosed herein, reference to
Figure 1 being made, a string is steerable through a multilateral wellbore system 10. The method includes assembling a string 12 with a bent or selectively angleable sub 18 for causing the string to enter a particular pathway. In the case of a bent sub, the string will enter a pathway when aligned therewith and in the case of an angleable sub, when the sub is angled toward that pathway selectively. The string also includes
an orientation measurement device 14 having one or more sensors therein such as those found in a commercially available MWD device such as a Baker Hughes Navi- Trak MWD device in order to determine orientation of a known fixed point on the tool relative to gravity, magnetic north, or other parsible environmental constant. Upon building the string it is known what the relative orientation of the bent sub 18 is to the orientation device. Therefore with knowledge by measurement of the orientation of the orientation device 14, the orientation of the bent sub 18 is easily calculable. The bent sub may be reoriented such as by rotation of a string upon which it is mounted to achieve a desirable result, that result being to enter a target lateral or primary bore at each junction encountered by the string. It should also be appreciated that a kickover device is employable to selectively kick the advancing string over to a desired leg. Kickovers may be spring type, hydraulic, etc. such as in Baker Hughes commercially available AutoTrak system.
[0020] The orientation sub further is configured to take other data while running which may be used for many purposes but specifically with respect to this method is employed to verify location of the orientation sub in the wellbore. Such data includes original drilling and well data, the parameters of which, when encountered again do indeed verify location. Orientation with respect to some constant and well logging information very effectively enable steering in a multilateral wellbore system providing that information is made available to a control center 20 capable of rotating the bent joint or causing the angleable joint to reconfigure. Such control center may be a downhole control center such as a processor or may be a surface location proximate the well head (not shown) or more remote. [0021] Delivering data gathered by orientation device 14 to the control center
20 is effected by telemetering device 16. Telemetering device 16 may employ a wireless or wired form of communication. Wireless forms of communication include ultrasonic transmissions, electromagnetic (EM) transmissions, pressure pulse telemetering. "Wired forms" as intended to include electrical, optic, etc. Data transmissions may be from periodic to continuous as desired. The foregoing provides for efficient, rapid and confident steering of a string through a wellbore. [0022] Referring to Figure 2, an alternate embodiment is disclosed which orients a junction or other well structure for deployment. Junction 30 may be of any type; the particular type of junction is not dispositive of the effectiveness of the method. It is notable however that the method is employable for junctions ranging
from level 3 to level 6 junctions of the TAML system of classification. In the illustrated embodiment, a level 6 junction is to be installed at a lateral borehole. Junction 30 is run in the hole on a string which includes and places within or downhole of the junction 30, an orientation measurement device configured for through passage of another downhole tool (not shown) such as a tripping ball, completion string, etc.
[0023] The string 12 is run in the hole and orientation measurements taken as in the previous embodiment. Rotation is imparted to the string as necessary to properly orient the junction for deployment. The employment of the components as noted significantly improves the likelihood of achieving a correct orientation of the junction in a single advancing movement of the string. In the event conditions downhole prevent correct orientation the first time, the string may be picked up and the process repeated as would be done in the prior art, however, in the using the method and devices disclosed herein, the orientation measurement device and telemetry device allow for pickup and re-rotation to be more precise thereby enhancing resultant placement.
[0024] As in the foregoing embodiment, orientation telemetry may be commenced when the junction is nearing target depth, may be periodic , may be continuous, or any other frequency or timing the particular installation or application requires or may be benefited from.
[0025] It is desirable to place the orientation measurement device as indicated in Figure 2 or Figure 2A because it provides a slightly earlier indication of misalignment. This facilitates realignment while the string is still running further downhole. Such is advantageous because it is less effective to rotate a junction without axial movement simultaneously. By placing the orientation measurement device downhole of or within the junction as stated, positioning/orientation thereof is more precise and simpler in operation. This is not to preclude however a placement above the junction, as illustrated in Figure 2B.
[0026] Referring to Figure 3, another embodiment hereof is discussed. In this embodiment the string 12 having orientation measurement device 14 and telemetry device 16 as set forth and utilized with respect to the foregoing embodiments is employed to assist the orientation and deployment, including running, setting and cementing of a hook liner hanger system 40 or other liner hanger system. In such a string, the orientation measurement device 14 may be mounted as part of the liner
immediately above or below the hook hanger or as part of the running string. Operation and telemetry of the orientation of the string is selectable as in the foregoing embodiments.
[0027] Because the orientation measurement device as used herein has a through bore as noted above, setting and cementing operations can be undertaken conventionally without additional runs in the well.
[0028] It is further contemplated herein to configure embodiments such that the orientation 14 and telemetry 16 devices are mounted in locations that provide the benefit of the devices as described above but are also not within the pathway of the tubing string. More particularly and referring to Figures 4, 4A, 4B and 5, one of ordinary skill will appreciate the locations of orientation 14 and telemetry 16 devices as appurtenant structures to the string 12 or junction 30. Since orientation 14 and telemetry 16 devices do not exist within the string, there is more leighway regarding their construction while not impacting well equipment movement through the string. [0029] In the Figure 4 embodiment, dead space in a splitter arrangement is employed to house the orientation and telemetry devices. This space is about 90° to the leg #1 and leg #2 as shown. Figure 4A is an end view of the Figure 4 device and illustrates both the orientation and telemetry devices in one of the dead spaces available. It will be appreciated that this could also be on the other dead space shown at 15. Figure 4B is an alternative arrangement where both of the previous dead spaces are used, one for each of the orientation 14 and the telemetry 16 devices. They may be located as shown or reversed with no distinction in effectiveness. Figure 5 illustrates an alternative where the orientation 14 and telemetry 16 devices are appended to string 12. Again, the devices are not an impingement on well equipment run through the tubing but still achieve the desired results. [0030] While preferred embodiments have been shown and described, modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way of illustrations and not limitation.
