ConocoPhillips and Canada's Canacol Energy Ltd. have failed to meet Colombian fracking requirements for projects in the northern Cesar province, according to a March 20 report from Reuters citing unnamed sources. Colombia shelved two environmental licensing requests.

The companies failed to meet minimum conditions for the Piranga project, while the Plata project raised possible water protection concerns.

Reuters said the two firms could request to reopen the licensing process for the projects in the future.

Conoco has an 80% stake in the projects while Canacol owns 20%.
