Prediction of Fine Reservoirs Interbedded with Thin Coals

Prediction for fine reservoir sands in the presence of coal beds through seismic reservoir characterization is hugely difficult, especially when the thin coal beds are interbedded with the sands. The observed seismic characteristics might not reflect the real characteristics of the reservoirs but rather a complex reflection interference of coals and sands that has a direct relation to the seismic resolution. In order to use the seismic characteristics to support the design of new development wells, and ensure successful drilling results, the distribution of the reservoir sands would need to be accurately predicted.
