Oil and Gas Transportation

Course Description

Study program: Petroleum Engineering (VII semester -OAS)

Name of subject: Oil and Gas Transportation

Instructors: Dr Dušan Danilović, Miroslav Crnogorac

Status: Compulsory

ECTS: 5

Prerequisites: Passed courses from the previous year.

Course Objectives: The aim of the course is to familiarize with the technology of pipeline transportation of oil and gas. The transport of oil and gas forms a significant part of the overall process of oil and gas production. Students study the dimensioning of pipelines for different types of flow and are familiar with all elements of the transport system (pipes, fittings, pumps and compressors). Special attention is dedicated to learning the API-5L standard, which defines all the necessary characteristics of the pipe. The selection of optimum pipeline parameters such as route, diameter, material quality and pressure class are analyzed in a timely manner. Investments in oil and gas pipelines as well as exploitation costs are also considered.

Learning Outcomes: Upon completion of the course, students are trained to design pipelines and gas pipelines and determine their optimal parameters and equipment.
