Quick Answer: What Is Azimuth In Directional Drilling?

What does Directional Drilling mean?

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..

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 are the in between points of direction called?

Intermediate Directions The directions on the compass that are halfway between these cardinal points are called northeast, southeast, southwest, and northwest. These in-between points are called intermediate directions. Globes and maps show only north-south and east-west lines.

What is the difference between inclination and azimuth?

The inclination angle measures the vertical direction and the azimuthal angle examines the horizontal direction. This measurement is relative to north, east, south and west. … This measurement is the difference between the actual and planned well paths.

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.

Are azimuth and bearing the same?

A bearing is an angle less than 90° within a quadrant defined by the cardinal directions. An azimuth is an angle between 0° and 360° measured clockwise from North. “South 45° East” and “135°” are the same direction expressed as a bearing and as an azimuth.

What is meant by Azimuth?

Scientific definitions for azimuth. … Azimuth is a horizontal angle measured clockwise in degrees from a reference direction, usually the north or south point of the horizon, to the point on the horizon intersected by the object’s line of altitude (a line from the observer’s zenith through the object to the horizon).

What is azimuth used for?

The azimuth is the angle between the north vector and the star’s vector on the horizontal plane. Azimuth is usually measured in degrees (°). The concept is used in navigation, astronomy, engineering, mapping, mining, and ballistics.

Why is a compass needed in order to find your azimuth?

Use your compass to determine or follow an azimuth. The arrow on the compass points toward magnetic north. The arrow is also attracted by any mass of metal-a truck, your rifle, your helmet, and even electrical power lines. Thus, be sure you use your compass away from metal objects so it will not give a wrong reading.

How does azimuth work?

Azimuth varies from 0° to 360°. It starts with North at 0°. As you turn to your right (in a clockwise direction) you’ll face East (which is 90°), then South (which is 180°), then West (which is 270°), and then return to North (which is 360° and also 0°).

How do you use an azimuth?

Hold the compass level, and rotate the azimuth ring until the specified bearing (such as 240°) lines up with the direction-of-travel arrow. Turn the compass, not the azimuth ring, until the orienting arrow lines up with the north end (usually red) of the magnetic needle.

What are the four main points of direction called?

North, east, south, and west are the four cardinal directions, often marked by the initials N, E, S, and W. East and west are at right angles to north and south. East is in the clockwise direction of rotation from north.

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 an azimuth on a compass?

An azimuth compass (or azimuthal compass) is a nautical instrument used to measure the magnetic azimuth, the angle of the arc on the horizon between the direction of the sun or some other celestial object and the magnetic north.

How far can a directional drill go?

Maximum lengths and hole diameters are determined by project specific geotechnical conditions however effective outside range for heavy rig horizontal directional drilling is 3,000 m (9,843′). Light rigs are typically used for crossings between 50 m and 1,000 m (164′ – 3,281′).

What is the sun’s azimuth when it rises?

The azimuth angle varies throughout the day as shown in the animation below. At the equinoxes, the sun rises directly east and sets directly west regardless of the latitude, thus making the azimuth angles 90° at sunrise and 270° at sunset.

How do you find the azimuth?

Therefore, an azimuth of 90° corresponds to a quarter of the way clockwise from 0° or 360°, which is east. Similarly, 180° is south, and 270° is west. You can get azimuths corresponding to NE, SE, SW and NW by adding or subtracting 45° to the appropriate N, E, S or W azimuth.
