%X The large isolated gas bearing channel belts of the Mungaroo Formation are for the most part easily identified on marine surface seismic (MSS). However a more quantitative interpretation of the reservoirs is often impeded by a combination of seismic noise and complex reservoir characteristics. Many sands are at or below tuning thickness and their amplitude response is affected by varying degrees of diagenesis. The presence of acoustically soft carbonaceous siltstones further compromise any quantitative interpretation. Using the Satyr field as a case study, this paper illustrates how recent advances in seismic processing are able to help mitigate some of the issues affecting MSS, such as free-surface multiple contamination. The paper then explores ways in which the resulting seismic products can be enhanced and manipulated to better discriminate lithologies, such as organic siltstones and cemented intervals. Wells within the Satyr seismic volume are used to demonstrate the improved reliability of reservoir quality estimates in support of field development planning. It is concluded that in certain instances targeted reprocessing of conventional MSS data using modern processing flows can go a long way towards delivering what might otherwise only hope to be achieved through a dedicated broadband acquisition.
