Before an oil company starts to develop an oilfield, detailed preliminary studies have to be carried out to decide whether a hydrocarbon reservoir is producible or not. If there is a potential reservoir, the next step is to determine how to set the parameters in order to produce in an efficient way. The present book describes a workflow from gathering geological and petrophysical data to simulating different flow scenarios of a hydrocarbon reservoir. The first part of the book is about the geography and the geology of the Escanilla Formation in the Ainsa Basin, Spain. The second part describes the methodology to get rock, reservoir and fluid properties and finally how to set the wells. In the third part the static and dynamic results of different flow scenarios are described. Last but not least there is a discussion about the different production scenarios with their advantages and disadvantages.
