Chevron recently achieved a technological feat in the depths of one of the world's largest underwater canyons. With vital right-of-way permits approved by the governments of the Democratic Republic of the Congo and Angola, Chevron has completed the drilling of a well intersection conduit beneath the Congo River submarine canyon, part of the Congo River Canyon Crossing pipeline project.

To create the intersection, two wellbores were drilled simultaneously from shallow water platforms located on each side of the canyon. One of the platforms is located in the Democratic Republic of the Congo while the other platform is located in Angola. The wellbores transitioned from vertical to horizontal, and then intersected almost midway beneath the canyon, approximately 2,000 feet (610 m) beneath the seabed, where the water depth is one-half mile (0.8 km).
