    Casing Backoff Tool
    Perform casing backoff in vertical and horizontal wells

    Applications

    Replacing worn or damaged sections of uncemented casing, in vertical or horizontal wells

    Benefits
    ■ ■

    Provides backoff solution for horizontal wells Simplifies operations by eliminating need for lefthand?drillstring Facilitates operations by leaving threaded connection for re-engaging new casing string after worn casing is?removed Supports further drilling by eliminating reduced casing drift diameter resulting from internal casing patches Contributes to operational safety by maintaining original casing strength and integrity Hydraulic anchors eliminate need for drill collar weight to achieve backoff Tool generates up to 60,000 ft.lbf Tool design eliminates need for overtorquing connections in a left-hand workstring on a “blind” backoff from surface







    Features


    ■ ■

    The casing backoff tool facilitates backoff of uncemented casing stumps at a selected coupling location downhole after a section has been cut and retrieved. The tool is effective in vertical or horizontal wells. The tool features nine subassemblies, including two hydraulic anchors and a torque generator. The hydraulic anchors allow the backoff tool to be used in horizontal wells because drill collar weight is not required to hold the anchors open. The tool is cycled, and, using hydraulic pressure only, the torque generator and anchors work in tandem to breakout and unscrew the casing threaded connectors with approximately one-half turn per cycle. When connection torque is sufficiently lowered, the backoff tool is pulled out of the hole, and a casing spear is run to complete the unscrewing and recovery of the casing stump. A threaded connection remains downhole for the new casing string to be stabbed into and made up. Schlumberger can also supply subs for aligning the old and new casing strings to facilitate proper makeup?downhole.

    External Casing and Tubing Patches
    Repair casing in regular or slimhole wellbores

    Applications Benefits
    ■ ■

    Restoring integrity to damaged tubulars in regular or slimhole sections Simple, economical installation Minimal impact on further drilling because it does not restrict casing?ID Lead or packer-type sealing mechanisms available Extensions for underwater wellhead applications available for packer-type patches Corrosion-resistant alloys (CRA) and low-yield alloys available for sour service wells by special order Regular or slimhole versions available

    Features
    ■ ■





    External casing and tubing patches are designed to repair damaged casing or tubing strings quickly and economically, without reducing the ID. The casing or tubing string must be removed to a point below the damaged section. The top of the casing or tubing stub is then dressed with a milling tool, and the patch is run over the casing or tubing to a depth sufficient to engage the slip. The external casing patch is available in standard and slimhole types. The slimhole version is ideal for small, restricted wellbores or for use below a restriction.

    Internal Casing Patch
    Applications


    Repairing downhole casing damage from corrosion or wear Sealing old perforations and leaking?connections Providing added protection to weak casing?points Reduced rig time for patch setting Minimal casing ID restriction once set Positive anchoring system during all subsequent operations Reliable PLI anchoring subassembly Effective without high expansion ratios





    Prior to setting the inner casing patch, it is recommended to perform a cleanout run. Brushing, scrapping, milling out previous plugs, and de-burring perforations should be handled during the cleanout run. Once the casing has been cleaned, a caliper or casing drift is recommended to ensure proper patch?size. The patch setting process involves tripping to the desired depth and dropped an activation ball. Once the ball is engaged, pressuring up to 1,800 psi initiates the anchor setting, and is completed in 1 to 2 minutes. Pressure then is increased to 2,000 to 3,000 psi for completion of the anchor setting. Once the anchor is set, increasing pressure to 2,500 psi shears the ball seat. Once the ball seat is sheared, picking up the workstirng with 25,000 to 30,000?lbf releases the setting tool from the casing patch body. When the workstirng is pulled through the patch with a force of 35,000 to 45,000 lbf, the patch expands and creates a seal across the repaired casing interval. Total pickup distance from start to finish is approximately?24?ft.

    The TMC fishing accelerator tool improves jar impact and provides a supercharged blow directly above the fish. Used in conjunction with the TMC fishing jar, the TMC accelerator tool maximizes jar impact regardless of depth because it can either replace pipe stretch as the energy source in shallow holes, or supplement the pipe stretch energy in deeper wells. The TMC accelerator tool’s robust design, materials quality, and comprehensive QA requirements ensure reliable performance in the harshest of fishing conditions.
    Note: The Jar-Pact fishing program should be utilized to optimize performance of accelerator tools and TMC?jars. Schlumberger recommends that the TMC fishing accelerator tool be used in conjunction with this tool. Contact Schlumberger for more information.

    Impression Blocks
    Impression blocks are used to determine the position and condition of the top part of fish or junk obstructing the borehole. Impression blocks feature a steel body that’s lower end is fitted with a block of soft material, typically lead. The tool is made up on the running string and lowered without rotation to make contact with the obstruction. The resulting contact with the obstruction leaves an impression on the block’s soft material that can be identified at surface. With this information, the appropriate fishing equipment can be deployed.

    Boot Basket
    Boot baskets catch debris that is too heavy to circulate out of the hole during drilling and milling operations. As cuttings flow past the boot basket’s larger OD, smaller OD, and its top connection, a sudden decrease in annular velocity is created, allowing the boot basket to trap junk. Boot baskets should be run as closely as possible to the mill, bit, or junk basket, and they can be run in tandem to increase junkretrieval capacity. Boot baskets are available in a range of sizes to run with most?BHAs.

    ■ ■ ■

    The Schlumberger Debris Catcher is a modular system, which uses reverse circulation to remove debris from the wellbore. Pumping through the tool provides energy to lift debris and fish from the bottom of the hole, object, or obstruction point. The lower end of the tool can be configured in one of three ways depending on the application, while the same jet section is used for all three applications:




    One application is a vacuum setup for removing small debris from a wellbore. The lower end of the tool uses a chamber for debris storage. When the job is completed, the tool’s trash cap can be removed and the debris chamber emptied without disassembling the tool. A second application is for fishing large debris from the wellbore. The tool’s debris chamber, on its lower end, is replaced with a rotary shoe which has an internal finger basket to capture fish. An additional application is for packer, plug, and milling operations. A?washover shoe is attached to the bottom end of the tool and milling debris is collected inside the tool. When the job is completed, the trash cap can be removed to empty debris from?the?tool.
