What are the reasons to have directional drilling?
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 does a directional driller do?
A directional driller operates machinery in the oil and gas industry to drill wells at multiple angles rather than just vertically. The objective is to drill a well sideways and horizontally to access different oil sources.
What is directional drilling and its application?
In general terms, directional drilling refers to the process of drilling a pilot hole along a defined route between predetermined entry and exit points. Directional drilling is useful because it makes the boring of underground holes without disturbing the surface possible.
Who invented the directional drill?
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 do directional drillers make?
Directional Driller Salary
| Annual Salary | Monthly Pay | |
|---|---|---|
| Top Earners | $70,500 | $5,875 |
| 75th Percentile | $60,000 | $5,000 |
| Average | $55,564 | $4,630 |
| 25th Percentile | $43,000 | $3,583 |
When was directional drilling invented?
The method, an outgrowth of the oil well drilling technology, was reportedly first developed in the early 1970s by Titan Construction, of Sacramento, California.
How is directional drilling controlled?
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 long has directional drilling been around?
Directional drilling began emerging in the late 1920’s when curvey instruments were developed that could measure both inclination and azimuth. The first controlled directional well was drilled in California in 1930 to tap offshore oil reserves.
