Provisional Application Ser. No. 60/496,151 filed Aug. 19, 2003, the entire contents of which is incorporated herein by reference.
BACKGROUNDIn 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.
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.
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.
SUMMARYDisclosed 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.
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.
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.
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.
BRIEF DESCRIPTION OF THE DRAWINGSReferring now to the drawings wherein like elements are numbered alike in the several Figures:
In a first embodiment of the method disclosed herein, reference to
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 re-configure. 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.
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.
Referring to
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.
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.
It is desirable to place the orientation measurement device as indicated in
Referring to
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.
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
In the
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.
