DEVELOPMENT OF CABLE-FREE SEISMIC TECHNOLOGY
Cable-free seismic technology refers to an acquisition method which uses receivers without a power cable connection. It is economical and offers advantages in terms of deployment and mobilization. KIGAM has developed several types of technologies related to cable-free seismic equipment, such as sparse acquisition, seismic interpolation, static correction and stratigraphic interpretation methods. KIGAM has also developed a prototype of a cable-free land nodal system and verified it through a performance evaluation. We will apply this nodal technology to explorations of fault zones, long tunnel designs, CO2 storage facilities, and deep seismic projects such as a project focusing on oil and gas resources in Myanmar.
Fig. 1. KIGAM has developed a prototype of a cable-free land seismic nodal system. Experimental testing of the prototype with commercialized nodes is shown.
Fig. 2. Comparison between the prototype nodal system developed by KIGAM and a commercialized system. The left graph shows the signal from the KIGAM prototype and the right graph shows the signal from the commercialized system. The results show that the first arrival times and phases are similar
