Exploration in frontier areas, where the target structures are poorly constrained by seismic images of low quality, requires geologic models and their seismic expressions to interpret the geophysical data. This paper proposes a methodology to combine two modeling techniques, analogue experiment and seismic modeling. Analogue experiments can provide admissible geologic models that constructed from regional tectonic environment and rock physics, and seismic modeling can produce the seismic image of the models. The experiments performed on a horst structure buried under thrust-belt (Deep Horst in Thrust-belt : DHT) showed that the horst height has significant impact on the sequential development of the thrust-belt. This suggests that such exploration targets may be discovered by examining geometric anomalies within the thrust-belt. The seismic modeling produced stack and migration images of the structure that can be used as templates to explore possible horst structures under thrust-belts.
