How far can directional drilling go?
These technologies are capable of reaching 10,000–15,000 ft (3000–4500 m) and may reach 25,000 ft (7500 m) when used under favorable conditions.

How long can you directional bore?
What are the minimum and maximum lengths of crossing? 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 ft).
How far can you horizontal directional drill?
Maximum distance and precision, minimal disruptions In the hands of our skilled operators, these machines are capable of placing pipe up to 60 inches in diameter to distances of more than 15,000 feet.
How much does it cost to jack and bore under a road?
For jack and bore, the cost is $3 to $4 per inch of pipe diameter per linear foot if line and grade are not critical. The cost is $4 to $6 per inch of pipe diameter per linear foot if line and grade are critical (Iseley and Gokhale, 1997).
How much does it cost to bore a water line?
Replacing a water line costs anywhere from $2,000 to $10,000 or more. You’ll spend anywhere from $50 to $250 per linear foot to replace the pipe.
What is the longest directional bore?
Michels continues to extend the possibilities of horizontal directional drilling (HDD) by completing a record length drill in North Dakota. The 13,247-foot (4,037-metre) drill allowed installation of a 20-inch pipe under the Missouri River.
How accurate is directional boring?
The accuracy of the tool is 0.01° in pitch and 0.04° in azimuth. At the same time the tool is not affected by magnetic fields from for example railways and cables.
Why is horizontal drilling better?
Directional or horizontal drilling allows producers more flexibility and precision in reaching and extracting oil/gas compared to vertical drilling. Horizontal drilling also reduces the ecological footprint of a drilling operation above ground by drilling in several directions from a single well pad.
What is the longest HDD in the world?
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 HDD technique?
2.2 HDD Technique HDD is a surface-launched, remotely controlled drilling technique using bentonite slurry to support the excavated tunnel, to transmit torque during pilot hole drilling and to transport the rock cuttings through a mud circulation system.
How do you calculate setback distance on a hard drive?
As a rule of thumb, the minimum setback distance can be estimated using a 5:1 ratio. For every 1 foot of depth, figure about 5 feet of horizontal displacement. So a 20-foot-deep well would require approximately 100 feet of setback.
