Abstract

The gas-bearing sands in the Barrosa Norte-El Triángulo field, Argentina are characterized by highamplitude<br>bright-spots on the stacked seismic data, and these anomalies have traditionally been used to<br>locate drilling sites. Drilling through these bright-spots has resulted in some pay and many dry wells.<br>Because the seismic reflection amplitudes are dependent on thickness, lithology, and porosity besides fluid<br>content, using bright-spots alone is ambiguous in detecting hydrocarbon sands from stacked seismic data.<br>To resolve the ambiguity, we use a 3D hybrid seismic inversion. This inversion provided a detailed and<br>accurate estimate of elastic earth properties, which were then used to calculate porosity and water<br>saturation maps for the reservoir.
