RESERVOIR ENGINEERING AND STORAGE

SSD: ING-IND/30, 5 CFU (57 hours)

Teacher: prof. Francesca Verga

LEARNING CONTENTS PRESENTATION

The course introduces the fundamental methods to assess the potential of oil and gas reservoirs. Key topics are the appraisal of well productivity and deliverability from well testing and well surveillance, the analysis of production data to evaluate the hydrocarbons originally in place and the production decline over time, the approach to reservoir management, and the strategies to improve recovery and possibly to convert depleted reservoirs into CO2 storages.

EXPECTED LEARNING OUTCOMES

The course aims to provide the student with the fundamental competencies of reservoir engineering. The expected learning outcomes are the ability to design and interpret a well test to assess the system and the well performance, familiarity with the methods for downhole well surveillance, skills to analyze real production data to apply material balance methods and perform a decline curve analysis, knowledge of production strategies, reservoir management and recovery enhancement methods, understanding of CO2 storage basics.

TEACHING METHODOLOGY

The course is delivered through live lectures with the support of slides. After presenting the theoretical background, real case examples and practical exercises are proposed. Students are asked to solve them and discuss their results with the Teacher. Lectures are delivered both by Polito and Eni personnel.
