The Use of Acoustic Impedance and Seismic Amplitudes to Identify Natih and Shuaiba Leads

The large reduction of oil prices has meant a focus of drilling of exploration wells to mainly low UTC, less risky plays. Reducing subsurface risks entails delivery of a robust well and seismic based framework to deliver good quality leads. Quantitative interpretation (QI), which has proven its value in prospect maturation, can also help at a play level evaluation.

This paper highlights the business impact of utilizing QI at an initial stage of prospecting in exploration.

Prospect evaluation identified structural and stratigraphic traps in shallow Early-Mid Cretaceous reservoirs in the Kauther area. Some of these demonstrated DHI’s (flat spots) in the seismic reflectivity dataset.

Seismic Inversion products support the presence of both good quality reservoir and hydrocarbons.
