Application of seismic technologies in the development of the Lower Tertiary D2N thin sand lithologic reservoir

Application of seismic information in reservoir development is the frontier of seismic technology. This paper illustrates how to predict thin sand via true 3-D interpretation, seismic inversion, and attribute analysis on seismic data from the lithologic reservoir of the Lower Tertiary Dainan Formation. For the two reservoirs in ques- tion, we firstly determine the factors controlling the characteristics of wave's peak and trough by analyzing the characteristics of seismic waves, and then predict the accumulated thickness of the reservoirs and the thickness of each reservoir using amplitude information of wave's peak and trough. The predicted results are in good agreement with drilling results.
