Gas Reservoir Engineering

via XuetangX

Overview

 Gas reservoir engineering is a course for the major of petroleum engineering and offshore oil and gas engineering. This course has 40 teaching hours for 2.5 credits.

21st Century is a century of natural gas. Natural gas is also a clean energy and key part of the world energy, which is very important for energy structure adjustment along with meeting the world energy requirement. Unconventional gases are the future of natural gas industry. How to develop the gas reservoir well is a main task for petroleum engineers. This course has 2 objectives, the first is to provide basic concepts and methods for gas reservoir development. The second is to help you work out a gas reservoir development plan, analyze the gas production performance and solve the problems encountered in gas reservoir development.

The course is divided into 5 chapters, including properties of natural gases, fundamentals of fluids flow in porous medium, gas volumes and material balance calculations,decline-curve analysis for gas wells, and pressure transient test of gas wells.  

  The course was founded in China University of Petroleum from 1984. With the development more than 30 years, the course was rewarded “Excellent Course of the University” from 2010, “Shandong Provincial Excellent Course” from 2013. From 2019, it was approved to be “Shandong Provincial Excellent Course” and conducted online teaching in “Zhihuishu”.

The course study is extremely valuable to you when you pursue your career in petroleum industry.
