Fluid Discrimination Applying AVA Potentiality for Carbonate Reservoir in UAE

Rock Physics Modeling Evaluation for Carbonate Reservoirs

“…AVO (Amplitude vs. Offset) analysis has been applied successfully as a geophysical technique since the 80's for a more reliable detection of amplitudes anomalies in the seismic, mainly, distinguishing gas-related amplitude anomalies and other types of anomalies for siliciclastic rocks (Ostrander (1984) (72) (63,52,67,36)). However, even the authors who work with AVO analysis are used to pointing out that the method has its limitations for carbonate rocks in the matter of reliable and confident inferences of fluids and lithological information of those heterogeneous rocks (Li et al, (2003) (63), Mahmoud et al, (2008) (67) and Isaac and Lawton (2009) (52)).…”

As a matter of fact, AVO analysis is a technique embedded in the so-called data-driven approach as well as seismic inversions (acoustic and elastic) and other approaches related to machine learning scope, such as: neural networks, support vector machines and others (Kuroda et al, (2016) (57) and Cersosimo et al, (2016) (29)).…”
