Definition - What does Horizontal Well mean?
Horizontal Well is a high-angled well which is built to increase the performance of the reservoir. During the construction of a horizontal well, a long wellbore section is placed in the reservoir. The well is characterized into three categories known as build rate, short radius and medium radius. The well is dug horizontally to get access to different oil and gas reserves from a multitude of angles. Horizontal Wells gained more popularity than vertical wells because they provide access to unconventional resources of the reserves.
Petropedia explains Horizontal Well
Horizontal Wells became popular with computer aided mapping and directional wellbores. A Horizontal Well allows a single well to reach multiple points, thus it is considered to be more productive and expensive than any other well. It plays an essential role during oil exploration as it minimizes the risk of introducing gas intrusion.
The following are the advantages of a Horizontal Well:
- It reduces the pressure drop of the wellbore.
- It minimizes the velocities of lower fluid.
- It increases the overall recovery of the reserves.
- It enhances the production rate of oil and gas.
