Role Of Seismic Attributes In Reserve Estimation

In Oil & Gas - Exploration and Development endeavors, there is no doubt that seismic data plays a huge and important role. In fact, it is considered to be the primary tool when we attempt to understand what we have in the subsurface. Seismic data however, is not that simple and has its own limitations. Seismic resolution for example is important to seismic interpreters and knowing the tuning thickness will help us know how much of the reservoir can be imaged vertically. In cases of low resolution, the thinner bed might not be imaged or can be seen only partially, causing the thin hydrocarbon bearing reservoirs to go undetected or unnoticed during seismic interpretation. The aim of this paper is to demonstrate using a case study from the Malay Basin, how seismic attributes may help in interpretation and identifying reservoir boundaries in areas below the tuning thickness and where interference from the above bed causes more challenges.
