Abstract

Summary

Hydrocarbon exploration in Mizoram area in the north-eastern part of India is an exigent task for the geoscientists which covered by thrusted-faulted complex geological setting with extremely difficult hilly terrain. Conventional 2D–3D seismic surveys are not achievable in such kind of hilly terrain areas and hence crooked line seismic survey work carried out. The depth of sedimentation is more than 10km in this area and seismic method is inadequate to demarcate the basinal structure. In that case, seismic interpretation is helpful with gravity and magnetic interpretation to delineate the basement structure, identification and correlation of localized dominant faults, valleys and sedimentary structures for better exploration and exploitation. An integrated interpretation has been carried out by selecting the three common profiles viz; seismic, gravity and magnetic simultaneously to demarcate the prospect location for the drilling. The higher probability prospect zone of hydrocarbons derived from the geochemical data are well correlated. Euler deconvolution technique has been used for the estimation of automatic source depth locations along these three gravity and magnetic profiles. The results are utilized for integration to reduce the exploration risk for delineating basement structures and to improve the confidence level for proposing the drilling locations.
