Chinese Scientists Develop New Geodetic Technology

Researchers led by Hu Wenbao at China's Yangtze University have successfully developed a new electromagnetic geodetic technology, a pivotal equipment for underground exploitation.

Through the technology, researchers, one the one hand, send electricity impulse underground with high-power electrical source, and receive the scattering from underground target with assembled equipment, thus to acquire relevant images. After analysis, the internal structure of the earth several meters or even dozens of kilometers can be grasped.

In March 2004, the technology was first applied in a carbonate rock area for exploration of oil and gas to collect information on the underground strata, structure, storage layer and pore belt.
