HORIZONTAL DIRECTIONAL DRILLING- INSTALLATION PROCEDURE This technique involves drilling a pilot bore, generally along a closely defined shallow arc, and then, if necessary, enlarging the bore using a reamer or hole opener to create a bore large enough to accept the new PE100 pipe, which is generally pulled in behind a reamer. We achieve continuous safety compliance through: Provision of appropriate and well maintained equipment. Although horizontal directional drilling can be a cost effective and environmentally friendly option (compared to traditional open trench excavations), it can be more difficult to avoid utility lines due to limited visibility.

In an oilfield with dispersed deposits, a large radius can be tapped, maximising the expensive asset which is the rig. Identification and review of hazards/risks associated with task execution. The drillstring itself will be less stressed when going in a straight line, every degree of turn add extra friction and unbalanced pressure. Model D550 Vermeer horizontal directional drill has an thrust/pullback of of 550,000 pounds and torque of 100,000 lb.-ft. This condition can quickly pressurize the formation and cause a heave at the surface. Safety is Horizontal Directional Boring number one priority. Before starting work, check for sources of interference. Pool Excavations. This is different from straightforward situations, where two territories happen to tap into the same reservoir. HDD drill bits. 'handtunneling.com' => 'handtunneling.com', Dont back fill a pothole until the back-reamer is clear and you are sure the existing utility is undamaged. I agree that directional drilling has a lot of advantages in construction which avoids having to cut open the ground when installing utilities so its important to hire a competent contractor to do it. Sometimes horizontal directional drilling is the only possible way to tap a reservoir, such as the case of dilling under a town or nature reserve. Hi Elena, At the destination, they would not need to keep drilling in a U-Turn, motors can be reversed and the equipment can come back out of the same existing tunnel/hole. Thorough training through application of our Field Level Risk Assessment Tool. Typical obstructions faced during HDD construction are cobbles and boulders, gravel beds, wood, bedrock, and construction debris or foundations. Horizontal Directional Drilling (HDD) is well suited for laying down plastic and metal pipes and lines for utilities, getting to hard-to-reach oil deposits without affecting the surface above, performing trenchless cable installations, and much more. If any changes in readings occur, like depth, the tracker should immediately signal the operator to stop drilling, investigate, and take appropriate safety precautions before continuing to drill. You have entered an incorrect email address! Simultaneous operations (SIMOPS) and combined operations (COMOPS) have strict procedures for situations where well interference can occur. We achieve continuous safety compliance through: Provision of appropriate and well maintained equipment. Only trained and qualified personnel shall operate horizontal directional drilling machines. Avoid defining individual job tasks too narrowly or too broadly; generally speaking, a job should contain no more than 10 individual tasks. JSAs need to be made readily accessible to inform employees about the hazards in their job tasks and what preventive measures will help keep them safe. Too often, employers spend time and effort creating JSAs only to have the documents disappear into a binder or filed away onto a computer hard drive and forgotten.

What happens is that at the correct depth the drillstring stops rotating, then drilling fluid is pumped through the mud motor so that the drill bit starts to turn just due to the force of the liquid. how the following factors affecting a proper technique selection to achieve your target: Common directional drilling patterns. Drilling parallel to existing Its interesting to know that the horizontal directional boring is still being refined to this day. Surface heave or humping is a condition that is usually a result of excess pumping of drilling fluids after a loss of circulation. Surface collapse is typically a result of a significant overexcavation above the bore hole, which can be caused by large volumes of thin drilling fluid used at high velocities, incomplete filling of the annulus with drilling fluids for a large-diameter bore near the surface, or leaks in high- pressure pipes after installation, which erode the soil above the bore hole.
