Field Trial Alaska


Identification of problem:

Provide a gas tight seal as a long term solution during well abandonment, reducing corporate liability and potential environmental impact, utilizing the Wel-lok M2M™ technology. This concept of using this technology had previously been proven in a laboratory environment but had yet to be field tested in an actual well.

Issues to overcome:

Conventional elastomer based bridge plugs and cement have been used for this purpose but neither provide a true, long term seal that is non-corrosive, gas tight and/or compatible with all downhole fluids and gasses.


15 Wel-lok M2M™ TS seals were run in multiple wells all set inside 4.5” tubing.

3 different wellbore temperatures

3 different well deviations


Tools were deployed, set and pressure tested successfully. The Wel-lok M2M™ technology was proven to be successful beyond a laboratory environment.
