Directional Drilling


 

         

GENERAL INFORMATION ABOUT EBI DRILLING (EBID)

 

 

EBID will inform the owner and any representatives as required prior to commencing work on the project.
 

EBID will complete a Utility Locate One Call at least 72 hours before commencing work on the project.
 

EBID will review the location of any/all marked utilities during the planning of any/all bores.
 

EBID will construct/set-up fluid containment pits/areas prior to commencing operations.
 

EBID will calculate safe pull strength for the specified pipe. 

 

 

 

PREINSTALLATION INFORMATION

 

 

Preparation

 

1. EBID will locate positions of entry and exit points, establish elevation and horizontal datum for drill bit control and an area to lay out and assemble pipe.

 

2. EBID will lay out and assemble pipe in a manner that will not obstruct adjacent roads and commercial or residential activities adjacent to construction easements.


 

Initial Drill Out (Pilot Hole)

 

1. EBID will initially drill out from entrance point to exit point following the vertical and horizontal alignment provided by the Owner/Project Engineer.

 

2. EBID will flag the alignment of the drill out at intervals of approximately 25 feet. EBID will not remove the flags until informed to do so by the Owner/Engineer

 

3. EBID will keep the hole open through the use of properly formulated drilling fluids and adequate pressure.

 

4. EBID will attempt to maintain the alignment within six inches of the grade and one foot of the horizontal location that were provided. Subsurface obstructions which cause greater deviations will be discussed with the owner/engineer before proceeding with the installation.

 

5. EBID will require the acceptance of the drill hole by the Owner/Engineer before proceeding with the installation. 
 

 

 

INSTALLATION

 

 

1. EBID will enlarge the drill out hole up to 1.5 times the outside diameter of the pipe(s) to be pulled in. The exact enlargement will be determined by subsurface conditions.

 

2. EBID will handle the pipe during the pull back in such a way to limit any potential damage to the product pipe.

 

3. EBID will attach tracer wire to the product pipe. Because the tensile strength of tracer wire is substantially less than that of the HDPE pipe, EBID cannot guarantee the successful installation of tracer wire. EBID recommends Copperhead HDD or equivalent tracer wire.

 

4. EBID will constantly observe the pressure gauges to maintain a safe pull strength on the given product pipe and to ensure safe torque pressure on the drill pipe.

 

5. EBID will perform the work in a fashion to minimize frac outs into water bodies andlor onto the ground surface.

 

6. EBID will monitor fluid returns as the installation proceeds as well as observing the area near the backreamer for potential evidence for loss of fluids due to frac out. If a frac out occurs, EBI will reduce the fluid pressure during the pullback and adjust the pullback rate in an attempt to bypass the area of weakness. EBI will work to remove any/all fluids as feasible. This would be done through the use of our vacuum trailer and containment pits/dikes as necessary.

 

In the event an uncontrolled frac out occurs that posses a risk to the environment, EBID will notify the appropriate agencies of the release at the following numbers:

 

Minnesota 1-800-422-0798
Michigan 1-517-373-8481
North Dakota 1-800-472-2121
Wisconsin 1-608-266-3232
Illinois 1-217-782-7860
Iowa 1-515-281-8694
Indiana 1-888-233-7745

 

EBID will work in conjunction with appropriate agencies to remediate any such frac out as instructed with the understanding that it is important not to cause more environmental harm in the attempt to remove nonhazardous naturally occurring materials.

 

 

 

COMPLETION

 

1. EBID will collect all excess non-contaminated residual drilling fluids and dispose of them in accordance with all federal, state and local regulations.

 

  

  a. EBID will not handle nor take responsibility for fluids that have been   impacted    by hazardous and/or regulated materials/substances in the subsurface. These fluids will be contained at the site and left for the owner to handle and dispose of.
