The New Horizontal Directional Drilling PowerTool (HDDPT) enables safe and efficient drilling, reaming, and installation of pipelines at road crossings, water bodies, and railroad right of ways.
Using HDDPT will lower construction risks and costs by providing:
Address all HDD Applications with the latest HDDPT Technology
HDDPT is specifically developed for professionals involved in designing, engineering, and installation of pipelines and utilities by horizontal directional drilling. HDDPT can be used for the design and installation of pipelines and conduits for the following applications:
HDDPT has all the engineering calculations needed to solve HDD project challenges quickly. The underlying mathematical models and technical procedures are based on the latest HDD technology, following current regulations, standards, and recommended practices. HDDPT addresses standard stress and pull-force analysis for steel and polyethylene pipe, drilling fluid hydraulic and pressure analysis, and addresses the installation of cables in conduits.
ANNULUS – the open space between the wall of the borehole and drill string.
BACK REAMER – is a drilling designed to enlarge and clean out a pilot hole.
BORING PROJECT CLASSIFICATION SYSTEM:
(XS) Extra Small Bore = less than 2”
(S) Small Bore = more than 2” – less than 4”
(M) Medium Bore = more than 4” less than 8”(L) Large Bore = more than 8” less than 24″
(XL) Bore = more than 24” less than 48”
(XXL) Bore = more than 48”
BENTONITE – is a clay material for making drilling mud and sealing the annulus.
Presents loss of drilling fluids
Supports borehole wall
Removes cuttings from the borehole
Reduces friction during drilling and insertion of materials
BOREHOLE – is a cavity created by the drilling process to pull a casing or pipe to complete the well.
CASING – is a pipe that comprises of the entrance and exit of a horizontal well.
CIC – Cables in Conduits
CSV file – Comma-separated-variable file (MS Excel compatible)
EICEbox – Suite of engineering application (EICEcube) modules developed by EICE
DRILLING MUD – is a slurry used to carry drill cuttings from the borehole, prevent collapse, and provide lubrication to facilitate the drill string.
HDD – Horizontal Directional Drilling
HOOP STRESS – is determined by Barlow’s formula: SH = Internal Pressure x Outside Pipe Diameter/2 x Pipe Wall Thickness
HYDRAULIC FRACTURE OR FRAC OUT – is when the pressure increases and fractures the formation, thus creating a pathway to the ground surface for the drilling fluids.
ICD – Interface Control Document
INSTALLATION STRESSES – Combined tensile, bending, and external hoop stresses that occur simultaneously.
LOCATOR – is a navigation system to determine the location of the drillhead depth and horizontal placement.
LONGITUDINAL STRESS – is determined by Barlow’s formula: SL = Internal Pressure x Outside Pipe Diameter/4 x Pipe Wall
OLE – On-Line Edition
OPERATIONAL STRESSES – Longitudinal and hoop stresses will result from internal pressure and thermal expansion/contraction like trenched pipelines. These stresses are used to evaluate the risk of failure.
PILOT HOLE – is the first borehole made in the HDD installation.
PowerTool – Standalone engineering application from skyBox
REAMER – is a cutting tool to enlarge the borehole.
RADIUS – The distance of a straight line from the center of a circle to its edge.
STRESS – The load per unit of area. Ordinarily, stress-strain curves do not show the true stress (load divided by area at that moment) but a fictitious value obtained by always using the original area.
TENSILE STRENGTH – The value obtained by dividing the maximum load observed during tensile straining until breakage occurs by the specimen cross-sectional area before straining. Also called ultimate strength.
TTL – Technical Toolboxes
UCD – User Control Document
YIELD STRENGTH – The stress at which a material exhibits a specified limiting deviation from proportionality of stress to strain. An offset of 0.2 percent is used for many metals such as steel, aluminum base, and magnesium base alloys. In comparison, a 0.5 percent total elongation under load is frequently used for copper alloys.
