Imaging of Deeper Events in Panidhing Area, Upper Assam, India

Summary The current thrusts for hydrocarbon exploration in Upper Assam Basin are the Deeper Horizons. Seismic imaging of deeper events in structurally complex areas is very challenging. As a case study, reprocessing of three, 3D volumes were acquired in Panidhing area was taken up to improve the continuity and resolution of the events. The three 3D volumes were reprocessed with Prestack merging, by meticulous analysis of the available geoscientific information and model based studies. The study shows that in a complex area where number of 3D volumes have been acquired, prestack merging in time domain has better edge over poststack merge. PSTM further improved the imaging thereby facilitating the interpreter to generate prospects with confidence.
