Horizontal Drilling - an overview ScienceDirect Topics

Horizontal drilling is a commonly used technology because drilling at an angle other than vertically can stimulate reservoirs and obtain information that cannot be done by drilling vertically. Horizontal drilling can increase the contact between the reservoir and the wellbore. As displayed in Fig. 8.5, the wells are drilled vertically until a depth that is above the shale oil reservoir is reached.
