Horizontally drilled wells dominate U.S. O&G production

In 2004, horizontal wells accounted for roughly 15% of U.S. crude oil production in tight oil formations. By the end of 2018, that percentage had skyrocketed to 96%.

The lateral length of horizontal wells has also increased, allowing for more exposure to oil- and natural gas-producing rock from a single well.

Presently, essentially all (99%) hydrocarbon production from the Marcellus has been from horizontally drilled wells.
