Revealing the Haushi interval with a pre-migration demultiple solution in the south of Oman

Seismic data from the south of the Sultanate of Oman presents unique challenges due to complex short-period surface and internal multiples generated in the upper section. This technical article introduces an innovative demultiple workflow designed to tackle these issues in the pre-migration pre-stack domain. The method combines least-squares multiple imaging with a one-way wave-equation multiple prediction, producing accurate multiple models while preserving key primary events. This approach enabled high-definition imaging of reflectors like the Ghadir Manqil and enhanced geological interpretation of the Haushi interval, supporting more precise tomographic velocity updates.
