Abstract
Summary
The main objective of this project was to evaluate the ability to estimate reservoir properties directly from broadband seismic without using well information for calibration. This estimation was achieved by using a combination of seismic velocity and pre-stack seismic inversion results. This was followed by a lithology-fluid classification in the pre-stack domain (acoustic impedance and Vp/Vs) and porosity estimation. The results are very encouraging and demonstrate the value of acquired broadband pre-stack data for identifying, delineating, and de-risking prospects and also for accurately characterising reservoirs properties without introducing prior pre-conceived reservoir models to bias the calculations.
