Company Description

In 2016 Winterhawk began developing a revolutionary and patented method to safely and effectively expand casing and other heavy-walled tubulars inside of wellbores.

Using the Casing Expansion Tool (CET), casing can now be used to improve annular integrity, not just to serve as a barrier between the inside and outside of the wellbore.

Materially reduce vertical communication of gas or liquids in the annulus to address methane flows to surface or interzonal communication
Return deformed casing to circularity in high-angle and horizontal applications without loss of integrity associated with milling or mechanical swaging
Expand heavy-walled tubulars for high-temperature, steel-on-steel seals or improve sealing on liner tops, liner hangers or casing patches
When used with remedial cementing, the CET functions as an external casing packer to ensure cement flows to where it is needed, not where annular and formation conditions force it to go.

Winterhawk’s casing expansion tools have been set, released and retrieved intact in dozens of varying wellbore applications.

The three-element assembly generates 12 or more expansions in a wellbore in one trip in the hole
The CET has successfully achieved 24 expansions in a single wellbore in two trips in the hole in less than one day of operating time
The question is not if Winterhawk’s CET works. The question is what wellbore problem do you want solved, and what is your ideal desired outcome?
