Horizontal drilling

Horizontal drilling

Drilling a portion of a well horizontally instead of straight down to expose more of the formation surface area to the wellbore without boring too many holes into the surface. Unlike a vertical well, a horizontal well can stretch for up to two miles along a shale deposit. In shale gas extraction, the lateral structure of horizontal drilling enables high volume hydraulic fracturing.
