Directional Drilling

Directional drilling refers to drilling toward a specific target. With directional drilling, operators may drill at an angle or slant, which allows them to reach a target without beginning the surface wellhead directly above it. Many targets downhole are directly below surface locations that are protected, environmentally sensitive, uninhabitable, or

Horizontal drilling is a type of directional drilling, where the well starts off at the surface and is directionally drilled to be at a 90-degree angle. Instead of producing through a formation and producing from a small portion of the rock, you turn sideways and greatly extend the wellbore’s contact with the reservoir rock.
