Objective
To improve drilling success in finding commercial gas reservoirs by increasing the knowledge of the reservoir characteristics before drilling wells. The Common Offset Stack sections are not the only usable tool to detect the gas. When properly processed, the seismic data can supply much more information. In order to achieve this purpose, a project of one year duration has been developed. This project will allow to the "inhouse" seismic experts to experiment and investigate the sensitivity of the seismic to reservoir characteristics. Work will include the preparation of data, processing, interpreting and testing the ideas using the accumulated knowledge in the area. This work will be done by the experts themselves rather than by having to rely on contractors with no experience in the area.
Analyzing the seismic amplitude variation with offset and studying independently the different parts of the Shuey's expression defining the said variation, two parameters are obtained which are in a direct relationship with the gas content in the sands, allowing a much better evaluation of the reservoirs before drilling.
The project will use all the available data: log information, core analysis, geological and test data to be integrated together with the seismic data and seismic (AVO) derived attributes. In fact up to 9 different seismic attributes can be obtained at present (amplitude at 0 m, amplitude at 1000 m, gradient, A0/grad, relative variation of Poisson's ratio,...). All this information is only partially and inefficiently used today, and the main goal of our project is to get a better knowledge of these attributes, because, probably some of them, or a new one, or a combination of them could supply valid information about the reservoir characteristics. In a first stage, integration of non compatible, market available, software packages will be converted into one single compatible package. At a second stage, interpretation of the data on each of the specific discoveries' locations will be compared against real well data in order to obtain seismic parameters which would allow to assess forreservoir characteristics. Finally, on the third stage, these results will be extended to areas where there are no wells, testing the new method by drilling wells. During this third stage a feed back to the project will come from the results of the new wells drilled.
