1. Introduct Introduction ion In this project, a 3D geological (static) model of a sample petroleum reservoir will be built. All steps will be shown in detail with screen shots of the necessary figures. he software to be used is Petrel™ , which is a product of !chlumberger, used to build 3D geological models of petroleum reservoirs. It was founded in "##$, and commercially released in "##%. It became part of the !chlumberger Information !olutions in &anuary '3. he project is divided in chapters as indicated in the etrel *or+flow ools shown in ig. ".". After some modifications and enhancements to the etrel *or+flow, the chapters will be presented as follows". '. 3. /. 1. $. 4. %. #. ". "". "'. "3.
