Locating sub system and method of orienting and/or positioning

The locating sub system and method for orienting and/or positioning a tool within a well-bore allow for orientation and positioning of one or more tools within a well-bore to perform precise operations within a well-bore. The locating sub apparatus can include a latching member that engages and causes a tubular member to rotate to a desired orientation and/or position for down-hole operations. The locating sub apparatus can further include a sacrificial sub that houses a latching member and a tubular member to traverse the well-bore to the site for down-hole operations. Upon completion of down-hole operations as desired or in an emergency, an upward force can be exerted upon the tubular member thereby disengaging an frangible member causing the tubular member to disengage from the latching member allowing for retrieval of the tubular member through the well-bore.

Description
FIELD

The locating sub system and method relates, generally, to locating apparatuses and methods for orienting and/or positioning a tool within a well bore.

BACKGROUND

When producing or completing a well, or performing other down-hole operations, a precise orientation and/or positioning of a tool is preferred to complete the desired down-hole operation. Performing multiple trips or procedures to complete the desired operation costs additional time, labor, money and resources. The improper positioning or orientation of a tool during an operation can cause irreparable damage to the casing or lining of a well or cause the collapse and loss of the well entirely. Additionally, the retrieval of stuck or lost tools down-hole can be a difficult and costly process. Other down-hole operations require precise positioning and orientation of tools to be performed correctly.

Known references, namely U.S. Pat. No. 6,568,480, describes the use of a coupling sub in conjunction with a well tool. The coupling sub is adapted to engage a receiver sub to orient and locate a well tool within a borehole. The coupling sub would then include an alignment key for engaging a certain azimuth profile. The alignment key is able to disengage when an upward or downward force is employed. The known implementation of an alignment key can create a problem whereby the coupling sub can slip out of the desired depth or location for well operations due to the ability of the alignment key to disengage so readily.

A need exists for a locator sub apparatus and method for orienting and/or positioning a well tool within a well bore that provides improved reliability and simplicity over conventionally available tools, while incorporating removal of the well tool from the well-bore.

A further need exists for a locator sub apparatus and method for orienting and/or positioning a well tool within a well bore that allows for a desired azimuth profile, orientation, direction or position more readily while preventing the disengagement of an alignment key.

The present locating sub system and method addresses these needs.

It is readily observed that the running tool 300 can pass through the upper portion of the sub 100A, through the latching member 200 and through the lower portion of the sacrificial sub 300. The locator sub system 20 is adapted for use such that it can be retrieved and reused. It is appreciated by those skilled in the art that different devices may be provided that would replace the sub 100A, the latching member 200 and the running tool 300 of the present disclosure. The replacements that achieve the same purpose and result as the sub 100A, the latching member 200 and the running tool 300 described herein would be within the scope and understanding of the present disclosure.

FIG. 12 is a flow chart illustrating a method or aligning a tool within a wellbore within the scope of the present disclosure. Further, provided by the present invention is a method for aligning a tool within a wellbore for performing a specific task. The method comprises the steps of engaging a latching member within a borehole at a specific depth and at a specific azimuth. Lowering a running tool into the wellbore such that the running tool passes the latching member. Pulling the running tool back toward the latching member and removeably engaging the running tool with the latching member such that the running tool is at the specific depth and at the specific azimuth defined by the latching member. Using the specific depth and the specific azimuth of the running tool to perform a specific task. Disengaging the running tool from the latching member for removing the running tool from the wellbore for reuse. This provides for the ability to make various measurements at specific locations and azimuths in the wellbore, provide perforations at specific locations and azimuths in the wellbore, and do other various and sundry tasks to better utilize resources.

Generally, in one embodiment of the locating sub system 10 (FIGS. 1-9), there is a latching member 200 that threadedly engages a sacrificial sub 100. It is to be appreciated that sacrificial sub 100 and sub 100A are interchangeable through out this disclosure. The latching member 200 of the preferred embodiment includes a slot or retainer 220 for engaging an arm or projection 352 of a running tool 300. The sacrificial sub 100 has an outer diameter smaller than an inner diameter of a wellbore or casing where the operations are to take place. The inner diameter of the sacrificial sub 100 is larger than an outer diameter of the running tool 300 that can operatively engage a well tool for performing operations downhole. The running tool 300 in the embodiment includes a projection or arm 352 that is pivotally secured to a body or enclosure 320 of the running tool and extends from within the inner diameter of the body or enclosure 320 through a window or opening 322 to protrude through the outer diameter of the enclosure 320. The projection 352 operates between an extended position and a retracted position. A biasing member 356 actuates the projection 352 such that the projection 352 is biased in an extended position. When in the extended position, the projection 352 operatively engages the latching member 200 when the latching member 200 is engaged to the sacrificial sub 100. The latching member 200 is positioned in the sacrificial sub 100 so as to allow the proper azimuth profile, depth profile or both for downhole operations. The sacrificial sub 100 of the disclosure includes channels or concaved portions 102, 104, 106 along the outer diameter surface of the sacrificial sub 100. The channels 102, 104, 106 allow lines, such as electrical line, wireline, slim-line, slickline or some combination thereof, to reach the well tool to provide power or control for the well tool while the locating sub system 10 is in the wellbore.

In another embodiment of the locating sub system 20 (FIGS. 5-7, 10-11), there is a latching member 200 that threadedly engages a sub 100A. The latching member 200 of the preferred embodiment includes a slot or retainer 220 for engaging an arm or projection 352 of a running tool 300. The sub 100A has an outer diameter smaller than an inner diameter of a wellbore or casing where the operations are to take place. The inner diameter of the sub 100A is larger than an outer diameter of the running tool 300 that can operatively engage a well tool for performing operations downhole. The running tool 300 in the embodiment includes a projection or arm 352 that is pivotally secured to a body or enclosure 320 of the running tool and extends from within the inner diameter of the body or enclosure 320 through a window or opening 322 to protrude through the outer diameter of the enclosure 320. The projection 352 operates between an extended position and a retracted position. A biasing member 356 actuates the projection 352 such that the projection 352 is biased in an extended position. When in the extended position, the projection 352 operatively engages the latching member 200 when the latching member 200 is engaged to the sub 100A. The latching member 200 is positioned in the sub 100A so as to allow a proper azimuth profile, depth profile or both for downhole operations.

In one embodiment of the locating sub system 10, a latching member 200 is included in the form of a tubular including an outer surface and an inner surface. The latching member 200 has an apex 212 at a first end and a connector portion 230 at a second end. The first end having the apex 212 and remote there from a guide 210 and a retainer 220. The retainer 220 may be in the form of a slot that extends from the outer surface through the inner surface of the latching member 200. In another embodiment, the central side terminates without the slot or retainer 220. In yet another embodiment, the central side terminates with a groove substantially situated along the inner surface while maintaining the integrity of the outer surface in the same location as the slot or retainer 220.

Further embodiments of the locating sub system 10 include a running tool 300 that has a tubular member or enclosure 320 having one or more end connections 310, 312, such as a threaded pin 310 or box end 312, for engaging one or more well tools, and an internal biasing member 356 connected to a moveable arm or projection 352. A frangible member 358, such as shear pin, screw, and/or ring, can be in operative association with the biasing member 356, such that the biasing member 356 can cause the arm to move between an extended position and a retracted position. The tubular member or enclosure 320 can also include a bore extending throughout the length of the tubular member 320 for use with one or more wire-lines, slim-lines, or a combination thereof

Further, the locating sub system 10 includes an arm or projection 352 pivotally secured to the enclosure 320 that is movable between a retracted position within or proximate to the enclosure 320, and an extended position for engagement with a slot or retainer 220 disposed within the latching member 200. The arm or projection 352 can also engage a groove situated on the inner surface at the low end of the first edge of the latching member 200. The arm 352 while in the extended position operatively associates with the first edge of the latching member 200 thereby causing rotation of the running tool 300 and any associated tool. In an embodiment, the arm or projection 352 operatively engages the slot or retainer 220 of the latching member 200 connecting the tubular member 200 to the latching member 200. In another embodiment, the arm or projection 352 may engage a groove set substantially on the inner surface of the latching member 200, thereby connecting the running tool 300 to the latching member 200.

The running tool 300, of one embodiment, includes a biasing member 356, such as by way of example one or more springs, that are in operative association with the arm or protrusion 352, such that the arm 352 is normally biased toward an extended position. While the frangible member 358, such as a shear pin, screw, and/or ring, is intact, the arm 352 is maintained in an extended position by the force exerted by the biasing member 356. Exerting an upward force in excess of the frangible member's 358 accepted limit upon the tool allows the frangible member 358 to disengage from the arm or protrusion 352. In one embodiment, a frangible member 358 shears when, for example, approximately one thousand pounds of upward force is exerted upon the locating sub system 10. It is appreciated by those skilled in the art that other embodiments may use a frangible member 358 of varying capabilities or types to provide the desired operative use for the particular situation, e.g., weigh, pressure, etc. Upon disengagement of the frangible member 358, the biasing member 356 causes the arm or protrusion 352 to move into the retracted position. This retracted position can cause the arm or protrusion 352 to be fully retracted into the running tool 300, or it can be substantially retracted while maintaining a portion of the arm or protrusion 352 substantially outside the inner diameter of the running tool 300. When the arm or protrusion 352 is in the retracted position, the running tool 300 disengages from the latching member 200 and allows for retrieval of a tool and the running tool 300.

An embodiment of the locating sub system 10 includes a sacrificial sub 100 having a first end and a second end. The first end allows for the latching member to be disposed within the inner surface of the sacrificial sub 100. A preferred embodiment of the locating sub system 10 includes a sacrificial sub 100 that has a first end and second end each with threaded inner diameters for selectively engaging the latching member 200. Other embodiments of the sacrificial sub 100 can include other forms of operatively engaging the latching member 200 to the sacrificial sub 100, such as bolts, grooves and indentions, among other forms of engagement. The sacrificial sub 100 may include one or more channels 102, 104, 106 on an outer surface of the sacrificial sub 100 to accommodate a control wire to operate the well tool as attached to the running tool. Of course, other embodiments of the sacrificial sub 100 within the locating sub system 10 may not include these channels 102, 104, 106, as a well tool does not necessarily have to be attached to the running tool 300. Further, the sacrificial sub 100 allows for the latching member 200, while in operative engagement with the enclosure 320 of the running tool 300, to traverse a wellbore in a particular orientation and/or position in reference to the well-bore.

An embodiment of the locating sub system 20 includes a sub 100A having a first end and a second end. The first end allows for the latching member to be disposed within the inner surface of the sub 100A. A preferred embodiment of the locating sub system 20 includes a sub 100A that has a first end and second end each with threaded inner diameters for selectively engaging the latching member 200. Other embodiments of the sub 100A can include other forms of operatively engaging the latching member 200 to the sub 100A, such as bolts, grooves and indentions, among other forms of engagement. Of course, as shown in FIGS. 10 and 11, other embodiments of the sub 100A within the locating sub system 20 may not include exterior channels 102, 104, 106, as a well tool does not necessarily have to be attached to the running tool 300. Further, the sub 100A allows for the latching member 200, while in operative engagement with the enclosure 320 of the running tool 300, to traverse a wellbore in a particular orientation and/or position in reference to the well-bore.

Another embodiment of the locating sub system 10 can traverse a wellbore to reach the site of operations within the well-bore. Once operations are completed within the wellbore, such as a tool retrieval, perforation, cutting, among other operations known in the art, the operator may cause an upward force to be exerted upon the enclosure 320 of the running tool 300. Upon an exertion of an upward force in excess of the frangible member's 358 limit, the frangible member 358 will disengage causing the arm or projection 352 to move into the retracted position causing the enclosure 320 to disengage from the latching member 200 that remains disposed within the inner surface of the sacrificial sub 100. Upon disengagement of the running tool 300 from the latching member 200, the running tool 300, with or without another associated tool, may be retrieved by continuing to exert an upward force. Additionally, in other embodiments, the locating sub system 20 can include a sub 100A that is retrievable from the wellbore.

The method of orienting and positioning well tool in respect to a wellbore of the preferred embodiment includes the steps of providing the interior of the wellbore with a sub that is in operative engagement with a latching member, the sub being inserted in a particular orientation directed in the direction for well operations to take place down hole. The sub and latching member are lowered into the wellbore. The sub and latching member can be associated with the running tool before insertion of the locating sub system into the wellbore or the running tool can be engaged to the latching member after the sub and latching member have been placed into the wellbore. The arm of the running tool engages a slot disposed between the inner diameter and outer diameter of the latching member. When the locating sub system has been delivered to the desired location for well operations and when the locating sub system is ready for retrieval, the operator causes a force to be exerted on the running tool thereby sheering a frangible member which disengages an arm from the slot disposed on the latching member. The running tool is then disengaged from the sub and latching member and is able to be retrieved.

It is understood that the steps of the method described above or as claimed is not required to be performed in the order as disclosed. It is further understood that not all of the steps are necessary to carry out the claimed method and different embodiments of the method may not use all of the steps as disclosed above.

While the present disclosure has been described with emphasis on certain embodiments, it should be understood that within the scope of the appended claims, the present locating sub system and method could be practiced other than as specifically described herein. Thus, additional advantages and modification will readily occur to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus, and the illustrative examples shown and described herein. Accordingly, the departures may be made from the details without departing from the spirit or scope of the disclosed general inventive concept.
