    Aeromagnetic surveys are very commonly under-interpreted. The potential value, captured during acquisition, is all too often unrealised at the interpretation and ‘action' stages of a project. I illustrated the fundamentals of robust aeromagnetic interpretation using telling case studies.The two keys to astute interpretation are:1. Understanding and full integration of local geology2. Adequate time applied to observation and interrogation of the aeromagThese tasks are very largely qualitative and simple (in a geological context), but they do take time. Fancy hardware and software is no substitute for incisive geological reasoning, and such reasoning cannot occur without time-consuming observation and data integration.Serving as an Executive Manager I equally supervise and implement the policies as agreed by the board.

    Besides making available the required tools for every staff, I employed my services as a Seismic expert. 3D depth migration has created many opportunities for exploration and production. At the same time, it has brought many challenges. An essential prerequisite for accurate imaging in depth is, of course, an accurate estimation of the velocity Earth model. Depth imaging essentially consists of two processes – traveltime computation and downward extrapolation of the observed wavefield through a suitable algorithm. For computing traveltimes, we need to start with an accurate depth-velocity interval model, which in turn, requires accurate reflection geometries in depth with layer interval velocities. During the process, one can check the various geologic hypotheses which match the observed data (i.e., whether the horizons and velocities used in the depth model make geologic sense). For this purpose, we combine the prestack velocity analysis and model building tools to obtain the accurate initial velocity model.Either layered or non-layered velocity models or a combination of two can yield the best possible Earth velocity model which may bridge the gap between geology and geophysics. In many geologically complex areas, especially in hilly terrain, we do not get velocity semblance that is sufficiently adequate to obtain a good velocity Earth model for the area. In such areas, estimation of the Earth velocity model has a certain amount of uncertainty regarding layer velocity and layer geometries. This I quantified with interpretation efforts and prior geologic information.
