What does horizontal drilling mean?
Horizontal drilling is the process of drilling a well from the surface to a subsurface location just above the target oil or gas reservoir called the “kickoff point”, then deviating the well bore from the vertical plane around a curve to intersect the reservoir at the “entry point” with a near-horizontal inclination, ….
What is directional drilling used for?
Directional drilling is a technique used by oil-extraction companies in order to access oil in underground reserves. Most oil wells are positioned above the targeted reservoir, so accessing them involves drilling vertically from the surface through to the well below.
Who invented directional drilling?
CherringtonThe Beginning. Horizontal directional drilling is an idea Cherrington first conjured up in the early 1960s when he was working for a utility installation company in Los Angeles. While out on a job, he witnessed another company doing some work nearby, using a hand-held air drill for a gas line installation.
Why is horizontal drilling better?
4.1 Horizontal Drilling 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.
How does horizontal drilling affect rock layers?
Once the vertical well reaches the deep layer of rock where natural gas or oil exists, the well curves about 90 degrees and begins drilling horizontally along that rock layer. … The pressure is powerful enough to fracture the surrounding rock, creating fissures and cracks through which oil and gas can flow.
How long does it take to drill a horizontal oil well?
Depending on the depth of drilling required and the type of drilling method used, a standard oil well can commonly advance from drilling to the beginning of production for an oil company within one to three months. However, drilling to production is only the last phase of work for an oil producer.
How is directional drilling done?
Horizontal Directional Drilling or HDD, is a steerable trenchless method of installing underground pipe, conduit, or cable in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area.

What is vertical drilling?
Vertical drilling is used by operators to access oil and natural gas reserves directly below a drilling site. Vertical drilling is performed before horizontal drilling occurs so that rock formations at different levels can be examined for potential oil or gas reserves.
What is the difference between directional and horizontal drilling?
2. Directional Drilling is the process of drilling which controls the direction and deviation of the boring programmed to the targeted location. Horizontal Drilling is the process of drilling where the direction of the well is horizontal. …
What is a horizontal oil well?
A horizontal well is a type of directional drilling technique where an oil or gas well is dug at an angle of at least eighty degrees to a vertical wellbore.
How does horizontal drilling change direction?
In order to be able to change the direction of drilling, the drill pipe cannot rotate as it does in traditional drilling. Instead, only the drill bit at the front end of the drill pipe is rotated. The drilling mud, which is constantly pumped down the pipe, is used as a source of power to turn the bit.

How does horizontal fracking work?
Horizontal Drilling and Fracking Horizontal drilling allows drilling vertically several thousand meters (typically 6,000 m) deep and then turning 90 ° and drilling horizontally. … A fracturing fluid is pumped under high pressure (ca. 100 bar) into the drilling pipe to widen fractures in the rock or to create new ones.
What is the difference between lateral and horizontal?
As adjectives the difference between horizontal and lateral is that horizontal is perpendicular to the vertical; parallel to the plane of the horizon; level, flat while lateral is to the side; of or pertaining to the side.
