Prime Horizontal Building Operator Confidence from Entry to Exit

Prime Horizontal’s mission is to develop and provide to its customers new and innovative guidance products and solutions for the steering of their difficult horizontal directional drilling (HDD) projects – projects for which conventional technology often proves inadequate. From the very beginning, Prime Horizontal has remained dedicated to this mission, thus developing an international reputation of excellence in both its guidance systems and service.

OUR GOAL

OUR GOAL

Prime Horizontal’s goal has always been to put its customers first by providing the most cost-effective and timely service with the highest degree of professionalism and ethical business practices. Prime Horizontal’s rapid growth in the years since its start has been a measure of its success in keeping its mission in sight and in reaching its goal for every project.

Since its inception, Prime Horizontal has been a driving force for the continuing development of systems and methods for tackling difficult crossing projects. Prime has done more than use conventional technology to solve field problems. Projects brought to Prime by its customers continues to lead to new, efficient and cost-effective solutions, thus adding more capabilities to Prime Horizontal’s toolkit and to customer’ options.

OUR CROSSINGS AND INTERSECTS

OUR CROSSINGS AND INTERSECTS

WITH PARATRACK…

Prime Horizontal’s success was initially based on the development in 1998 -1999 and successive improvements of the ParaTrack system of horizontal guidance. Originally developed by Vector Magnetics as an underground parallel-drilling location system, the ParaTrack system was co-developed and continues to be improved by Prime Horizontal and Vector Magnetics for specific application to the HDD market.

Steering of the drill bit is performed by first measuring the location of the drill bit relative to its planned track using magnetometers and accelerometers in the ParaTrack steering tool. The magnetic field from an external magnetic source, typically a large coil of wire through which is passed an AC electric current (ParaTrack-2) or a DC electric current (ParaTrack-1), is measured at the steering tool with the magnetometers in the tool and the location relative of the drill bit is computed and passed to a display unit in real time so the driller can adjust the drilling parameters to stay on track. Additionally, wireless AC sources give the necessary precision of plus or minus a few centimeters to complete intersect crossings underground, and ParaTrack-2 is the only steering system today capable of measuring and analyzing AC magnetic fields.

Magnetic sources include both wire-based coils and non-wire based magnetic sources with the ParaTrack-2 system, including the Axial Magnet sub, the Rotating Magnet (RM) Sub, the AC Beacon, and the AC Benchmark making possible many new steering applications, especially for the completion of intersect crossings requiring maximum precision where the crossing is completed entirely underground with the intersection of two drill bits, one drilling from the entry side and the other drilling from the exit side.

With the addition of the Pressure While Drilling (PWD) Sub to the drill string, ParaTrack-2 also measures pilot-hole annulus and internal pipe pressure at the steering tool.

We have used ParaTrack-2 in the freeze drilling of tunnels. Freeze drilling is a technique used in the tunnelling industry when the tunnel must be bored in soft, unconsolidated sediments which collapse as the boring operation takes place. To prevent this collapse, many small, parallel bore holes are made through which is circulated a slurry of freezing brine. After the surrounding formations are frozen solid, the boring operation can continues to completion. The tolerances are very small for the brine holes and the ParaTrack-2 system meets these tolerances when used with the MicroCoil magnetic source (the Naples Metro project} and with the Rotating Magnet source (the Hallandsås Rail Tunnel project still ongoing).

OUR ROTATING MAGNET RANGING

OUR ROTATING MAGNET RANGING SERVICE

(RMRS)

The Rotating Magnet Ranging Service (RMRS) is typically used for horizontal to vertical well intersections for production of Coal Bed Methane (CBM).

The RMRS kit consists of a Rotating Magnet Sub, of length approximately 18.5 in, which sits between the bit and the mud motor of the horizontal, directional well. This sub contains stacks of powerful rare earth magnets that create an AC magnetic field when rotating with the bit. This magnetic field is monitored by the ParaTrack-2 Sensor Probe located in a nearby vertical well on wireline, with a usable range of up to 220 ft (67 m), and provides a distance and direction from the Sensor Probe to the Drill Bit.

OUR PRODATA

OUR PRODATA

While driven by Prime Horizontal’s presence at the drill site, a significant departure from our conventional service business has been the development of ProData, our purpose built rig data display and transmission system.

On every drill site you will find in one form or another 3 fundamental components, The drilling rig itself…the front line of the operation, the power pack providing the hydraulic energy to drive the drill, and the mud system, providing lubrication and transport for the cuttings removed from the drill face.

The Pro Data system is designed to measure drilling parameters from each of its sensors built into and around the drill site, whether they are rig, mud or power sensors.

Signals from the sensors are transmitted via a blue tooth wireless connection to the logging module on the drill site where it is viewed by the rig operator. From here the collected information is transmitted to a central database where it may be viewed graphically online through our client web portal in the client office.

OUR DRILLING TOOLS

OUR DRILLING TOOLS

While Prime Horizontal started as a HDD service company, our presence at the drill site and our knowledge of the drilling operation quickly led to providing drilling tools to our customers. Now, we offer a complete line of drill bits, hole openers, reamers and mud motors, together with a field mobile break out unit for the in-field repair of motors. We also provide sales of the ParaTrack system as well as training in the use of ParaTrack.
