Parameterisation of Pointbars in High-Resolution Seismic Data

We developed a simple method to parameterise fluvial point bars, which are common sedimentary deposits in meandering river environments. The method needs four points defining the point bar and is based on high-resolution seismic data. A model geometry is compared with the real point bar geometry. We optimise the model parameters by minimizing the error in the area covered by both objects. The method was applied to real seismic data from an oil reservoir in South America.
