Multiple attenuation was successfully performed on land seismic data in the difficult Abu Dhabi sand dune and sabkha environment.The keys to success were careful analysis plus selection and application of carefully designed data-adaptive multiple attenuation workflows.The demultiple success on the South East Abu Dhabi seismic data described in this paper was the result of a unique workflow developed specifically for this survey.Development of the workflow depended on rigorous analysis and consistent feedback from interpreters and geophysics specialists.Multiples with similar prestack moveout with offset to the primary events were successfully modeled and removed from seismic data to produce higher quality final seismic images.Onshore seismic data from the high sand dune South-Eastern Abu Dhabi area suffers from strong ambient noise and multiples that make exploration efforts difficult.Although a variety of techniques and algorithms exist for modeling and removing multiples from seismic data,there is no single method that is appropriate for all cases.Successful projects for the most difficult onshore multiple problems are often the result of careful analysis,selection and application of the right technology and the use of an appropriate data-adaptive workflow.The demultiple success on the South East Abu Dhabi seismic data demonstrates that with the proper tools and feedback it is possible to developed a workflow that can attenuate even the most difficult multiple noise.
