Horizontal drilling is a drilling process in which the well is turned horizontally. Normally, this type of drilling is used to extract energy from a source which runs itself horizontally, for example – a layer of shale rock. This process is commonly used to extract gas from the Marcellus Shale Formation.
Because the horizontal section of a well is at great depth, it is essential to include a vertical part as well. Thus, a horizontal well resembles the letter “J”. When it comes to the difference between horizontal wells and vertical wells, it is easy to sea that through horizontal drilling a much wider area of rock can be reached as well as the natural gas trapped within that rock. This means that with the use of horizontal drilling and techniques, one can reach more energy by using fewer wells.
