Is horizontal drilling expensive?
Horizontal drilling is expensive. When combined with hydraulic fracturing, a well can cost up to three times as much per foot as drilling a vertical well. The extra cost is usually recovered by increased production from the well.

Is horizontal drilling better?
Drilling horizontally, parallel to the geologic layers in tight formations, allows producers to access more of the oil- and natural gas-bearing rock than drilling vertically. The lateral length of horizontal wells has also increased, allowing for more exposure to oil- and natural gas-producing rock from a single well.
What are the top oil drilling companies?

How is horizontal drilling done?
Horizontal or directional drilling is done by using a mud motor. The drill bit is on the bottom of the motor and the bottom portion of the motor can be set at angle from 0 to 3 degrees. Only the drill bit rotates, the rest of the BHA (bottom hole assembly) is slid.
What is horizontal drilling technology?
Horizontal directional drilling (HDD) is a basic trenchless technology that involves drilling into the earth to create a horizontal bore under the surface along a planned pathway through which pipes and conduits may pass.
What is horizontal oil drilling?
Horizontal drilling is a technique for oil and natural gas extraction involving a well dug parallel to the wellbore, with the assistance of flexible piping, allowing people to go sideways in addition to straight down. This technique is an example of directional drilling, a practice developed by…
