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 using 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.
