What is it about?
It is about calculating rock properties from well log data of the Vaca Muerta Formation, and predicting the same properties away from the wells by conduction a process of Seismic Inversion. Then the results are interpreted in a geological framework.

Why is it important?
The develope of Vaca Muerta have recently become one of the most important project for oil companies in the Neuquén Province in Argentina. The Fortin de Piedra block is the first massive developed area for organic-rich shale reservoir (unconventional reservoir) in the Neuquen Basin. To know how the rock properties changes vertically and laterally, including Total Organic Content (TOC), helps to found the sweet spots to locate wells with higher productibily. Help reduce geological uncertainty during drilling and completion.
Perspectives
Several rigs are currently drilling in the Fortin de Piedra Block to develop the resources in Vaca Muerta. An important increase of gas production is expected. The more drilling the more information that can be used to update the results, and get more accurate predictions.
