Why directional drilling is done?

Why directional drilling is done?

Directional drilling increases the efficiency of oil and gas extraction, and can also lessen the environmental impact of drilling. Although directional drilling has been used since the 1920s, modern technological improvements to the technique have increased its accuracy and safety.

What is HDD technique?

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 are directional drilling tools?

The most common deviation tools for directional drilling are steerable motor assemblies (or so-called positive-displacement motors [PDMs]) and rotary steerable systems (RSSs).

Can you directional bore through rock?

In the past, the presence of rock formations prevented the use of horizontal directional drilling (HDD) for most underground utility construction. As technology has advanced, midsize drilling equipment now has the capability of effectively drilling and steering in rock.

What is the longest directional bore?

To meet the fuel demands of the expanded Hong Kong International Airport (HKIA), new twin aviation fuel pipelines were installed using horizontal directional drilling (HDD) by Langfang Huayuan Mechanical and Electrical Engineering Co., Ltd.

What is Seagate Pipeline HDD?

Pipeline HD drives provide system designers. with uncompromising performance for today’s. video streaming applications. Pipeline HD drives. spin at a unique speed of 5900 RPM.

What is the difference between horizontal and directional drilling?

A more complex way of directional drilling utilizes a bend near the bit, as well as a downhole steerable mud motor. Horizontal drilling is any wellbore that exceeds 80 degrees, and it can even include more than a 90-degree angle (drilling upward).

What is the difference between directional and horizontal drilling?

Who invented directional drilling?

The 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.

What is directional drilling and does it work?

Directional drilling is a process that helps utility crews lay pipes and cables without digging trenches . It can save a construction company time and money while creating a line that can be used by the community for years to come.

What are directional drills used for?

Directional drills are mainly used to drill gas or oil from the ground. As the name suggests, directional drilling allows drilling for things like oil and gas at various angles, rather than just vertical (straight down), which greatly increases the efficiency and return of a drilling operation.

How does horizontal directional drilling work?

Horizontal directional drilling works by directing the drill bit in a different direction from the wellbore axis while the entire drillstring is not rotating, which is achieved by pumping drilling fluid through the mud motor.

The most common deviation tools for directional drilling are steerable motor assemblies (or so-called positive-displacement motors [PDMs]) and rotary steerable systems (RSSs). Adjustable-gauge stabilizers, known as “2D rotary systems,” have become quite popular to run with the rotary and PDM assemblies to control inclination.
