An annular plug
as unique as your well

Throughout its lifecycle, each well presents its own challenges. The integrity, safety and performance of your asset can be impacted by increased and/or unwanted water production, or integrity issues like sustained casing pressure. To overcome this you need a solution that’s as individual as your well.

Our annular isolation solution precisely delivers a seal to your well.

Using a tailored sealing solution, we accurately plug the annulus in both vertical and horizontal wells. Delivered in a single well run by our patented downhole delivery tool, CannSeal technology extends the life of your well.

Re-establish the integrity of your well
Extend field life and improve recovery
Advanced production facilities

We have developed state-of-the-art testing facilities at our HQ in Stavanger, Norway, to ensure that every stage of a project can be rigorously analysed and tested before deployment.

Along with our production facilities, with several planetary mixers for large-scale epoxy production, we have a fully-equipped lab for reviewing and qualifying our solutions. 

To simulate real well conditions, we have invested in a 40-meter-deep test well, with full temperature and pressure capabilities, as well as an 18-meter-long horizontal test well.
