Seismic Data Analysis to the Converted Wave Acquisition: A Case Study in Offshore Malaysia

Many fields in offshore Malaysia suffer from the presence of shallow gas cloud which is one of the major issues in the basin. Seismic images underneath the gas cloud often show poor resolution which makes the geophysical and geological interpretation difficult. This effect can be noticed from the am...
