STANDARD CASING REPARATION EMERGENCY BACKOUT SUB™

In addition to the standard models, Dril-Quip also offers an Emergency Backout Sub for use in highly deviated wells where rotation of the casing is not possible. Deviated wells make the Rotation Free (or RF) Emergency Backout Sub an excellent choice because it can withstand the high tension and compression loads experienced in deviated holes. The field-proven RF Emergency Backout Sub and the RF Tie-back Tool are available in a variety of casing sizes. Contact your Dril-Quip representative for more information.

ROTATION-FREE CASING REPARATION EMERGENCY BACKOUT SUB

Dril-Quip’s Casing Reparation System is an equipment solution for production wells that have developed holes or leaks in the production casing string. If the casing can be disconnected below the damaged area and retrieved, an Emergency Backout Sub can be run and made up to the casing string. There are two types of Casing Reparation Systems; the standard and the “RF” type. The standard Casing Reparation System is a cost-effective choice for repairs occurring in vertical and shallow wells, while the RF type is a better choice

USING THE STANDARD AND RF

in deep or deviated wells. This is because the RF Tie-Back Tool does not require casing rotation to make up; an inner sleeve that rotates independently of the Tie-Back Tool makes up to the Emergency Backout Sub. When landed, simple weight set engages the RF Tie-Back Tool to the Backout Sub. Drill pipe is run and makes up to the Torque and Test Tool with right-hand rotation. Additional right-hand rotation torques the Tie-Back Tool to the Backout Sub and energizes a metal-to-metal seal.

The weight of the Tie-Back Tool engages its Adjustment Sleeve to the starting position in the Backout Sub.

CASING REPARATION SYSTEMS

Casing strings frequently get stuck when casing is run into deviated holes or in areas of problem formations (steps 1 and 2). The Emergency Backout Sub solves this problem easily. The casing above the Emergency Backout Sub can be disconnected and retrieved with right-hand rotation (STEP 3).

USING THE EMERGENCY BACKOUT SUB

• Fast and safe operation

• Compatible with standard casing programs

• Metal-to-metal seals provide pressure capacity compatible with the casing

• Provides adjustment of the casing string length between two fixed points

• Eliminates the need for slip-type casing hangers

• Engineered for strength and pressure integrity

• Available for standard or H2S service

• Full-bore design

• Field-proven performance

FeatuRes

The Dril-Quip Adjustment Sub eliminates the need to cut casing and set slip-type hanger assemblies in the surface wellhead system. This unique design eliminates BOP stack nipple up/nipple down procedures, thereby saving valuable rig time and providing safer drilling operations.

ADJUSTMENT SUB™

The Adjustment Sub solves costly stuck casing problems that occur in floating, bottom-supported or land drilling operations. Using the Adjustment Sub in conjunction with the Dril-Quip Emergency Backout System makes cutting and patching stuck casing a thing of the past.

The threaded section of the adjustment sleeve is designed to transmit the load in shear, rather than tension, resulting in high load-carrying capacity. Torque requirements are reduced because the adjustment sleeve thread is not subjected to tension loads during setting operations.
