A shallow well generally refers to a design drilled to a relatively shallow depth compared to other types of wells. Operations often drill these wells where oil deposits are close to the surface or within shallo. Barge rigs work in shallower waters, usually less than 20 feet deep. After being floated to the drilling location, the hull is brought to rest on the ocean floor, creating a stable platform for drilling. Many barge rigs operate in the Gulf of Mexico and around the world.
