What is a horizontal drill used for?

What is a horizontal drill used for?

Horizontal directional drilling (also called HDD) is a method that is used for trenchless drilling. Horizontal drilling is used for the placement of underground infrastructure like: water pipelines. telecommunication cables.

What is horizontal directional drilling machine?

Horizontal Directional Drilling (HDD) is a method of installing underground pipelines, cables and service conduit through trenchless methods. It involves the use of a directional drilling machine, and associated attachments, to accurately drill along the chosen bore path and back ream the required pipe.

What is the process of horizontal drilling?

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 an advantage of horizontal drilling?

The advantages of using horizontal drilling include: Durability, as the pipes are very strong. Quicker installation with less disruption to landscaping. Lower installation cost with a smaller crew.

When was horizontal drilling invented?

The first patent for a horizontal drilling technique was issued in 1891. The main application was for dental work but the applicant noted the same techniques could be used for heavy-duty engineering. The first true horizontal oil well was drilled in Texas in 1929.

What is HDD in construction?

Horizontal Directional Drilling (HDD) has become a favorable method of pipeline installation in urban areas and for crossing obstacles such as rivers and roads. HDD is defined as a steerable system for the installation of pipes, conduits and cables in a shallow arc using a surface-balanced drilling rig.

What is a HDD machine?

Horizontal directional drilling (HDD) machines are steerable, trenchless drilling rigs for the installation of pipes, conduits, and cables underground in a shallow arc. They are commonly used for installations below waterways and roadways to avoid disturbing the ground above.

What is HDD profile?

Horizontal directional drilling (HDD) is a steerable trenchless method of installing underground pipelines in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. Directional boring is used when trenching or excavating is not practical.

Who invented horizontal drilling?

As a utility installer in Los Angeles in the early 1960s, Cherrington came up with the concept of horizontal directional drilling. While on the job, he saw another business installing a gas line nearby using a hand-held air drill. When Cherrington learned about guided drilling, he was inspired to research the subject.

What is the difference between vertical and horizontal drilling?

Vertical well drilling allows access to oil or natural gas reserves directly below the surface. While horizontal drilling allows operators to access reserves over a wider underground area, vertical drilling can only access reserves directly below the end of a well.

How much oil does a horizontal well produce?

The Oklahoma Watch study shows that a typical horizontal well’s oil production starts out with a bang, averaging 267 barrels a day during the first full month of production.

What is the advantage of directional drilling?

Directional drilling is much more cost effective compared to digging a trench to replace any underground piping. Since the entire process takes much less time and much less dirt to replace when the project is finished and it uses less machinery compared to a regular method. Less machinery means lower cost.

Why is horizontal drilling harmful?

Horizontal drilling in the Marcellus shale involves large volume hydraulic fracturing, which poses a number of risks to aquatic species and habitats. This type of hydraulic fracturing requires about five million gallons of water per well, with 1-3 wells per pad.

Who made the first horizontal directional drill?

The method, an outgrowth of the oil well drilling technology, was reportedly first developed in the early 1970s by Titan Construction, of Sacramento, California.

What is Jack and bore?

Jack and Bore is a trenchless method of sewer construction. It is suitable for installing short pipe runs in stable and dry soils without large boulders. Crews dig a sending pit and a receiving pit to install a new sewer pipe.

What is HDD machinery?

What is HDD design?

HDD Analyser is a comprehensive program for the design analysis of pipelines crossings by horizontal direction drilling methodology.

What is pitch in HDD?

Pitch tells the operator the downward angle necessary to take the drill head to the depth where the path of the bore will be leveled off, and pitch information is used when the drill head needs to be aimed upward toward the targeted exit point, or when needing to avoid obstacles.

How many wells are in a pad?

Today, a drilling pad may have five to ten wells, which are horizontally drilled in different directions, spaced fairly close together at the surface.

When did horizontal drilling become popular?

The turning point when horizontal drilling went mainstream can be dated quite precisely. “Before 1990, horizontal drilling was not a popular technique. The oil industry only drilled horizontal wells as a last resort,” Schlumberger explained. “The global total for 1989 was just over 200 horizontal wells.
