One of the main objectives of the oil & gas business is to produce hydrocarbons economically. Three macro-phases make up this industry: exploration, field development and production.
The course focuses on field development and the activities aimed at production optimization throughout field exploitation - which is usually between 10 and 25 years.
Field development (average duration 4-8 years) covers all the activities an oil company puts in place to convert an exploration discovery into commercial field exploitation.
A field development project is an extremely complex activity for many reasons: it is multidisciplinary, it requires large investments, it has to be sustainable, it involves risks. Risks are mainly related to future oil prices as well as to reservoir uncertainties, and they strongly affect the economic return, which is the business objective.
The course is aimed at illustrating how to deal with such complexities from both the strategic and the design points of view.
Risultati di apprendimento attesi
The course will provide the elements for deciding the optimal development scheme among all possible options.
Students will learn how to select the main technical components of the production system that maximize the project’s economic return and minimize the impact on the environment, namely: reservoir well patterns, drilling and completion, artificial lift, oil & gas process, export hydrocarbon system, offshore structure.
They will also acquire knowledge about the project management workflow structure along with planning and cost estimation, and the calculation of the economic indicators used to select the optimal development scheme both from a deterministic and a probabilistic points of view.
Finally, students will learn the main elements of the current petroleum international contracts and the methods for maximizing oil & gas production.
Prerequisiti / Conoscenze pregresse
As the course is oriented to illustrate professional practices and standards, it is obvious the students should have good knowledge of the concepts discussed in previous courses, mainly: reservoir engineering, drilling and completion, hydrocarbon processing and economics. In addition, some knowledge of risk analysis would be helpful.
• International petroleum contracts (1 lesson). The three main international petroleum contracts are illustrated: Concession, Production Sharing Agreement (PSA) and Service. In addition, upstream basic agreements are presented: Memorandum of Understanding and Joint Operating Agreement.
• Economics of oil & gas fields (2 lessons). Applications of classical economic indicators (NPV, IRR, MFE, POT) to petroleum projects are illustrated by the use of examples and case studies.
• Petroleum risk analysis (2 lessons). Decision tree analysis and Monte Carlo method are applied to real problems of risk management in upstream field development and in well production problem solving.
• Project management (2 lessons). The phases of field development projects are illustrated: Evaluation, Definition, Execution, Commissioning & Start up, Production. Emphasis is on Planning and Costs.
• Workover and artificial lift (2 lessons). Main types of well interventions (workover) are discussed and the following artificial lift systems are presented: sucker rod, gas lift, electrical submersible pumps, jet pumps.
• Production optimization (2 lessons). Nodal analysis is illustrated in order to understand the full fluid dynamics system (from reservoir to market) and production trouble shooting.
• Field development schemes (1 lesson). The main schemes of development for on shore and offshore are discussed. Both for oil & gas.
• Case studies of field developments (2 lessons). Various case studies of field development are illustrated, both oil & gas, onshore and offshore. For each case the focus is on the critical aspects that in reality needed most of the investment and/or special studies and deepening.
Organizzazione dell'insegnamento
The teacher will use 20-40 slides per lesson in order to facilitate the understanding.
At least one third of the time of each lesson will be dedicated to numerical examples that derive from the teacher’s 37-year experience.
Case studies will be illustrated focusing on critical aspects or big challenges: possible options will be addressed in class. Students’ suggestions or ideas will be discussed with the teacher and with other students. Finally, the solution (what happened in reality!) will be presented.
Testi richiesti o raccomandati: letture, dispense, altro materiale didattico
The slides of the course will be distributed to the students at the end of each lesson; consequently, the full set of slides (about 500) will constitute the main document for preparing the exam.
