IQ-BORE EZ-BOREHOLE PROFILER 

 

sq_borehole.jpgHandheld.jpgTwo-directional  Portable EZ-BOREHOLE PROFILER ( IQ-BORE ) is designed for magnetically clean applications and includes SOLID STATE advanced Pitch / Roll / Temperature compensated miniature compass system. It is built around a state of the art Cortex microcontroller utilizing AOSI’s proprietary algorithm on a 0.9″ x 2″ x 0.5″  assembled PCB.

IQ-BORE system includes 1.5” diameter 18.5” long IQ-BORE probe, color handheld display controller and cable. The new directional IQ-BORE probe is able to provide total borehole profile information. The IQ-BORE displays borehole and tool face directions, X-Y-Z magnetic fields, borehole pitch, tool roll and temperature in its integrated handheld controller.     Click to view USER MANUAL

The handheld display controller includes a color display, four touch keys in a soft rubberized case. The system is powered by a single 9Vdc cell. Advanced Cortex processor monitors all communications with the IQ-BORE probe, sends and receives user commands and displays graphic and numeric data on the screen. All displayed data is in real time.  The system also includes special reinforced abrasion resistant cable. Due to the systems modular construction the cable is available in various standard and custom lengths and marked depth increments of “1ft, 5 ft, 10ft, 1m, 3m, 5m”. .

IQ-BORE can profile both VERTICAL as well as HORIZONTAL boreholes, therefor there is no need to have two separate borehole deviation probes (one for each orientation). The user does not need to retract the probe or go through prolonged setups and re-calibration procedures in order to switch between orientation modes.

As IQ-BORE senses the real time direction of the borehole, there is no need to install borehole casing, resulting in IQ-BORE operating in holes with casing and without. Super flexible cable facilitates secure gravitational resting orientation of the probe against the interior wall of the borehole before each reading.

Single click instantly switches from vertical profiling mode to horizontal, or vice-versa. This is achieved by sensing magnetic field of Earth together with pitch and roll orientation of the sensing IQ-BORE head. Then it uses AOSI’s algorithm to accurately calculate the 3D orientation of the IQ-BORE and its direction.

AileronRoll.gifWhile in Horizontal mode, the IQ-BORE operates in a special ( Aileron Roll mode ). Just like a rolling jet flying forward rolling around its longitudinal axis, the magnetic probe while at any roll orientation inside the borehole, still outputs accurate borehole direction. Accurate direction is maintained at borehole inclinations of -75 to +75 degrees. This advanced feature sets the IQ-BORE apart from other borehole profiling tools.For inclination angles above |75| degrees, it is recommended to switch to a vertical mode.

This system is perfectly suitable for numerous Trenchless applications like HDD (horizontal directional drilling) and verification of prescribed paths for underground conduits, pipes and cables. The probe can detect and display deviations and/or deflections in horizontal directional drilling drills trajectory attributed to fractured formations or formations changing from soft to hard and back to soft sections.

IQ-BORE can be most useful in any of the following directional drilling applications where other methods are more expensive or not feasible:

Borehole steering

Power cable installation

Crossing waterways and roadways

Water/sewer/gas/oil line installation

Telecommunications conduit installation

Pipeline and environmental inspections

Congested intersection & shore approaches

Reduction of flyrock during blasting

Balancing explosive energy to volume of blasted material

Users can operate the IQ-BORE in both PUSH-IN and RETRACT direction with selectable depth segment settings of 1ft, 5ft, 10ft, 1m, 3m and 5m.

Simple file retrieval software lets users transfer files between IQ-BORE to any PC. Profile and rear views of measured boreholes including TRUE VERTICAL DEPTH ( TVD ) are easily viewed with same software.
