This means that the standpipe kill graph of a deviated well has a different curve as compared to the graph prepared for a vertical well due to the behaviour of Pdp.

Highly Deviated and Horizontal Wells SpringerLink

A horizontal well may be defined as a well which is drilled to an inclination of 90°, and maintains this inclination for a significant distance. Owing to the need for special equipment and the longer drilling times that must be expected, horizontal wells are considerably more expensive than conventional deviated wells.

Mar 01, 2020  Among many issues encountered in a complex well trajectory, poor hole cleaning is the most common problem, which occurs mainly in the deviated and horizontal section of oil and gas wells (Xiaofeng, 2013). Inefficient hole cleaning affects the penetration rate, and consequently, causes fluid loss, lost circulation, and stuck pipe.

Horizontal Drilling Directional Drilling: Natural Gas Wells

Done together, horizontal drilling and hydraulic fracturing can make a productive well where a vertical well would have produced only a small amount of gas. Drilling Methodology. Most horizontal wells begin at the surface as a vertical well. Drilling progresses until the drill bit is a few hundred feet above the target rock unit.
