Abstract

Fault detection carried out by coherency technique gives wonderful results, when data quality is wonderful. Even coherency is also not needed to identify fault. Poor data quality in deeper part of the areas are very challenging to interpret faults or fractures due to loss of amplitude and frequency. A phase volume is not sufficient to confirm the fault/fractures in this type of data. In this paper a very simple low amplitude enhancement technique by inverse of trace method was proposed and applied in Bengal basin data which satisfactorily confirm the fractures in seismic section and found confusing by coherency method. The process is very simple and it can be done by any interpretation software by any geoscientists in no time who knows workstation little bit. This technique also helps to clearly identify dim spot rather most dimmed area among other dim areas.
