Language of instruction
The course target is to provide participants with a basic understanding of the nature and main characteristics of a hydrocarbon reservoir and its related study and development techniques.

Educational objectives
This course aims to develop a fundamental knowledge of the fundamental geological and petrophysical concepts and apply this knowledge to understand the reservoir geology.
In order to understand and know how to apply the techniques described in the course of teaching, it is very important for the student to know the basic concepts of sedimentology, structural geology and applied geophysics.
Teaching methods
The course is organized in frontal lessons and in practical lessons on Petrel software
In particular, the course is organized in 4 modules:
1st module: Introduction to the fields
2nd module: Data and their integration
3rd module: Field study
4th module: Modeling Field Exercise

Learning verification modality
End-of-course exams are written and are organized as a test schedule. The test lasts no longer than 120 minutes and is intended to verify the ability to correctly apply the theoretical knowledge and the ability to understand the proposed problems.
Extended program
Module 1: Introduction to the fields
• Introduction to the World of Oil
• Introduction to ENI E & P
• The phases of life of a field: activity, duration, economic impact
• Exploring the exploration activities for discovery of a field
• The development of a reservoir
• Managing the production behavior of a field
• Field studies at different stages of the life of an asset

Module 2: Data and their integration
• Different source of static and dynamic data
• Characteristics, advantages and limitations of any data type:
• seismic interpretation
• log log and interpretation of logs
core analysis
• production test
• other types of data
• Integration of data from different sources

Module 3: Field study
• Goals and workflow
• Definition of geological layering and identification of dynamically separated compartments
• Petrophysical Characterization of Tank Rock
• Construction of the geometric 3D model of the field
• Distribution in the 3D model of facies and petrophysical parameters
• Calculate the volumes of hydrocarbons in place
• Transferring the model to the flow simulator
• Flow simulation of the field - objectives and workflows
• Objects on non-traditional fields (thin layer deposits, fractured deposits, deep-water reservoirs)

Module 4: Modeling Field Exercise
• Introduction to the Case Study
• Analysis of available data
• Correlation between wells and definition of geological layering and fluid contacts
• Calculation of the medium petrophysic properties of the field and its levels
• Modeling the structure and internal geometry of the field
• Distribution of Petrophysical Properties
• Calculate the volumes of hydrocarbons in place
