Drilling Calculations Spreadsheets. May be you are having some of these from elsewhere, but it gives me great pleasure to compile all these at one place. I did not delete the references of original makers of these spreadsheets, if it is there, so all the credit goes to original makers of these calculation spread sheets only.
Horizontal Directional Drilling 421 Chapter 12 Horizontal Directional Drilling Introduction The Horizontal Directional Drilling (HDD) Industry has experienced so much growth in the past two decades that HDD has become commonplace as a method of installation. One source reported that the number of units in use increased by more than a hundred-
1. Horizontal Directional Drilling Rig – to be specified by the Contractor. 2. Drill pipe and trail stem – to be specified by the Contractor. 3. Drill bits and reamers – Contractor specified – generally based on the soils and drilling conditions to be encountered. 4.
Horizontal Drilling 101. Horizontal drilling is a decades-old well stimulation technique, where pressurized fluid is injected into rock to create small, millimeter-thick cracks kept open by a proppant material – typically sand – to allow natural gas and oil to flow more freely. Horizontal drilling has reinvigorated the production of oil and ...
Horizontal Directional Drilling Plan – February 29, 2012 . Figure 2. Typical Entry Site Layout. 3.0 SCHEDULE . For a drill of this length, with a pull back of 10 inch HDPE pipe, the anticipated schedule is set out in Table 2: Table 2. Anticipated Schedule. Day Activities .

for the tough jobs, the DD-440T is the go-to drill rig for contrac-tors around the world because of its versatility and strength. Rapid Set-Up horizontal directional drills are unique to American Augers. The DD-660RS and DD-1100RS allow the driller to pull the rig into position, then rapidly rises to the desired drilling angle. Both
c. Include electronic m onitoring of horizontal and vertical drilling head location. Obtain accuracy range within 1 inch of actual position of pipeline. Record position readings at maximum of 10 foot intervals. d. At completion of pilot hole drilling, furnish Contract Manager tabulations of horizontal and vertical alignment. 3.
Horizontal Directional Drilling (HDD) is a construction technique whereby a tunnel is drilled under a waterway or other designated area, and a pipeline or other utility is pulled through the drilled underground tunnel. The underground tunnel follows an arc line from the entry point, down

Where Horizontal Directional Drilling is planned to be undertaken as part of a Project to RSC07 UDC Civil Works specification, a pre-start meeting shall be held in conjunction with the pre-start meeting requirement in that specification. 8.2 Elsewhere .
SPECIAL CONDITIONS FOR HORIZONTAL DIRECTIONAL DRILLING (HDD) November, 2007 Page 1 of 4 1 Materials 1.1 Pipe Approved materials for HDD include: medium-density polyethylene (MDPE), high-density polyethylene (HDPE), steel, fusible PVC, restrained joint PVC, and ductile iron pipe. Alternate materials will require prior approval.
Horizontal drilling is a process of directing a bit to drill along a horizontal path oriented approximately 85 to 95° from a vertical direction, whereas multilateral drilling is a process of drilling lateral holes from a main trunk such as horizontal, vertical, or directional (Fig. 13).
. Drilling Manual. The purpose of this article is to understand how to perform various directional drilling survey calculation methods and terminology and we will provide a simple excel spreadsheet to help in your calculations as average angle, radius of curvature & minimum curvature Directional surveying spreadsheet.
The components of a horizontal drilling rig used for pipeline construction are similar to those of an oil well drilling rig with the major exception being that a horizontal drilling rig is equipped with an inclined ramp as opposed to a vertical mast. HDD pilot hole operations are not unlike those involved in drilling a directional oil well.
