Introduction To Well Control for Horizontal Wells
Introduction To Well Control for Horizontal Wells. Currently, horizontal wells are widely drilled around the world because the production from the horizontal wells is outperform normal vertical or deviated wells at the same location. The productivity of the well increases because of longer penetration into a pay zone and/or more intersection of ...

Horizontal Well
A horizontal well is a process of drilling a well turning to a horizontal direction from a vertical wellbore at a specific depth. It deviates by a specified angle from the conventional straight-down drilling approach. It has been in existence since the early 1900s. However, a hydraulic fracturing technique made it a widespread drilling technique.
