People often think of drilling as going straight down through the ground. However, in oil extraction, there is a method more efficient than vertical drilling. Horizontal drilling is the process in which the well changes direction horizontally at a depth. The drilling will start with a vertical process first then turn horizontally at a certain entry point. This technique can reach and collect more energy with fewer wells. It is known to be the best strategy for drilling shale rocks.
Although this type of drilling has a more intricate process, it has been proven by geological research that it yields more benefits than the conventional one. Targets and reservoirs that cannot otherwise be reached through vertical drilling can be tapped through the horizontal method. It can reach natural oil deposits trapped in tight shale formations located more than a mile below the ground.
Another benefit of horizontal drilling is its ability to reach large areas with just a single drilling pad. When this directional drilling is combined with hydraulic fracturing, it can convert unproductive shale rocks into reservoir rocks. There are more benefits such as: installing underground facilities, sealing out-of-control wells, and improving the productivity of wells.
