Previous seal studies (for example, Sales, 1997) had revealed that the actual amount of oil and gas to be<br>accumulated were controlled by (or could be calculated from) the top seal capacity in relation with a level of spill-point.<br>Furthermore, Sawamura and Nakayama (2005) proposed the method of evaluating top seal capacity in terms of equivalent<br>grain-size (EGS) (Fig.1). It was successfully explained for the fields under the hydro-static condition. In this paper, the same<br>concept was applied to multi-reservoirs in anticline structure with abnormally high pressure condition where the pressure<br>increases as we go deeper layers, an example from offshore Sarawak, Malaysia.
