Wide Field Electromagnetic Instrument
The Wide Field Electromagnetic Instrument is an ultra-high-power electromagnetic transmission system. Its transmitter delivers 1500 volts and 180 amperes of output power. The system operates across a broad spectrum of 404 discrete frequency points. This range extends from a very low 0.0034Hz to a high 9600Hz. The instrument transmits multiple pseudo-random step wave signals simultaneously. It uses an 8-channel receiver to capture the ground’s electric field response. A key innovation is its calculation of accurate apparent resistivity from a single electric field component. This process works across wide survey areas without traditional “far zone” limitations.
Construction involves a heavy-duty transmitter, a separate multi-channel receiver, and a large battery array. The system is built as an open platform, supporting various electromagnetic survey methodologies. Its intelligent control unit manages the complex transmission sequences and power output. Despite its high power, the design emphasizes operational logic for field deployment. The primary technical achievement is its validated exploration depth capability of 8,000 meters.
The Wide Field Electromagnetic Instrument is designed for deep resource exploration. Energy companies use it to map structures for oil, gas, and shale gas reservoirs at extreme depths. Geothermal prospectors apply it to locate deep dry hot rock formations for energy projects. Mining firms employ it for basin-scale analysis to find deep-seated metal deposits and coalbed methane. Hydrogeologists utilize it to understand regional deep aquifer systems. Its deep penetration makes it a strategic tool for national-scale geological assessment and frontier exploration.
Tactical Supply Pakistan sources this premier deep-probing system for major exploration initiatives. We facilitate access to technology capable of revealing subsurface resources beyond the reach of standard method.
How does a single-component measurement enable such deep exploration?
The instrument’s proprietary wide-field algorithm transforms this simplified data. It calculates accurate apparent resistivity at great depths without complex multi-sensor arrays, streamlining field operations.
