Question: What Is The Difference Between Directional And Horizontal Drilling?

How does a horizontal directional drill work?

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..

Is horizontal drilling the same as fracking?

Horizontal drilling allows more of the wellbore to remain in contact with the producing formation, increasing the amount of oil or natural gas that can be recovered. … Hydraulic fracturing is a completion technique, meaning it is performed after the oil or natural gas well has been drilled.

How far can you directional drill?

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′).

How do you get into directional drilling?

To become a directional driller, you need excellent mathematical and problem-solving skills, an understanding of mechanics, and patience. Attend a program at a directional drilling school; such programs can last up to eight weeks and teach the necessary skills and responsibilities of directional drilling.

Is fracking cheaper than drilling?

Fracking is expensive, but still less costly than the methods used to obtain oil from the wells mentioned above. According to Reuters, estimates put the break-even point for fracking at around $50 per barrel, but other estimates put it as low as $30 per barrel.

How far horizontally does fracking go?

Horizontal drilling can extend more than 1 mile (1.6 km) from the vertical well bore, according to Texas A&M University’s publication “Hydraulic Fracturing and your Private Water Well.”

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.

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.

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 long does it take to drill a horizontal well?

Can take a total of 1-2 weeks to drill each well, depending on depth. Will drill vertically down to “pay zone” or target formation, then curve until bit is horizontal and drill horizontally in target formation for desired length.

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’s bad about fracking?

Hydraulic fracturing, or “fracking,” is revolutionizing oil and gas drilling across the country. However, without rigorous safety regulations, it can poison groundwater, pollute surface water, impair wild landscapes, and threaten wildlife.

How do they do directional drilling?

A more complex way of directional drilling utilizes a bend near the bit, as well as a downhole steerable mud motor. In this case, the bend directs the bit in a different direction from the wellbore axis when the entire drillstring is not rotating, which is achieved by pumping drilling fluid through the mud motor.
