Installation, manipulation, and remediation of downhole hardware
Welltec’s array of mechanical, cleanout, and milling services are engineered to address a wide variety of hardware challenges. For increased efficiency, two or more services can often be combined in a single run. When combined with the Well Tractor®, these services can be deployed in high-angle and horizontal wells.
Our modular mechanical solutions provide the backbone for addressing hardware challenges. At the core is the Well Stroker® that can apply up to 100,000 lb of axial force in either direction. The Well Stroker can be fitted with a wide range of shifting tools, including the Well Key®, to handle any mechanical shifting operation. Modified versions of the Well Key can also be used to manipulate shift to release packers or lock open a SSSV.

Our modular cleanout tools have proven to be beneficial in cleaning and restoring functionality to SSSVs and other well hardware. The Well Cleaner® Power Suction Tool efficiently removes sand and other particulate debris, whereas the Well Cleaner® Wishbone Honer effectively polishes equipment that requires a smooth surface to function properly.

Deployed on e-line, our modular milling tools have proven to be robust and highly effective in removing well components that are malfunctioning or no longer required with robotic precision.
The Welltec RCB (Reverse Circulating Bit) integrates a rotary bit with a suction system to provide the combined benefits of both in one tool. This design breaks through hard packed debris and recovers the cuttings into the integrated bailers.
The Well Miller with Expandable Bit for hardware milling provides operators with a better way to repair wells with mechanical obstacles. It can pass through small ID and expand to a larger OD when activated.
The Well Stroker can push or pull multiple times in the same run irrespective of the depth and deviation. It delivers up to 100,000 lbs of axial force downhole by the use of a bi-directional hydraulic ram.
The Well Key Dimple Tool is designed to permanently lock open surface controlled subsurface safety valves in a single run.
Efficient, safe drill pipe, liner, tubing and casing recovery operations without the need for explosives. The Well Cutter uses a rotating head to remove pipe incrementally, which prevents the creation of shavings.
Our clean-out solutions ensure access into new wells and optimized production from old wells: removing sand and debris; cleaning SSSV seats; clearing obstructions; eliminating scale deposits; accessing isolation valves.
