Horizontal Drilling

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. It’s sometimes referred to as unconventional drilling. Horizontal wells have become more popular in the past decades, but they can have higher drilling costs for a variety of reasons.
