Restoration of Well Access

Through efficient and economic remediation of well restrictions and obstructions

Downhole Access

Well restrictions and obstructions play a major role in the diminished performance of producing wells. Also, these flow barriers interfere with the ability to properly identify and remediate other possible sources of production declines. Welltec’s array of efficient and economic wireline-deployed downhole access solutions can restore lost production and facilitate further diagnostic measurements and corresponding well interventions.

Wide variety of challenges

Welltec’s array of milling, clean-out, and mechanical services are engineered to address a wide variety of Downhole Access challenges. For increased efficiency, often two or more services can be combined in a single run. Furthermore, when combined with the Well Tractor®, these services can be deployed in high-angle and horizontal wells.

Our modular milling tools have proven to be robust and highly effective in removing restrictions and obstructions with robotic precision. Whether you are experiencing scale, collapsed pipe, a faulty valve, or a pre-set frac plug, our milling services are up to the challenge.

Downhole safety valves

Repairing a downhole safety valve (DHSV) reinstates well integrity and allows a well to be put back on production. Repairing tubing retrievable subsurface safety valves (TRSSSV) saves having to perform a lock out operation and from having to install a wireline retrievable subsurface safety valve (WRSSSV) which will restrict production.


Clean-Out tools

Our modular clean-out tools have proven to be beneficial in maintaining and restoring production across diverse environments. To keep production optimized, periodic interventions with our clean-out solutions can remove the unwanted by-products associated with oil and gas production including sand, scale, mud, etc.

Well cleaned

As the intervention leader for 25 years, Welltec introduces its new revolutionary 3-in-1 Cleaning Solutions in multiple sizes—providing safer, faster, and more reliable operations for higher efficiency and performance.

From the game-changing Well Tractor® to our fully combinable industry-leading mechanical solutions, we have a complete portfolio of services to be your one-stop-shop.

Mechanical solutions

Our modular mechanical solutions effectively address downhole access challenges. The Well Stroker® can apply up to 100,000 lb of axial force in either direction to pull a crown plug or push an obstruction below the production zone. The Welltec® Puncher can quickly drill multiple uniformly-sized holes through tubulars to establish circulation or equalize pressure.
