    Natural Gas Reservoir Engineering

    This course will take a comprehensive look at several aspects of gas reservoir engineering. The course can be constructed such that it is a fundamental, intermediate, or advanced gas reservoir engineering course. This course will cover various techniques, including basic gas reservoir engineering, properties of natural gas, material balance, and gas reserve determination.  Other concepts that will be covered include gas deliverability, nodal analysis, and well testing in gas reservoirs.

    Day 1

    Basic Gas Reservoir Engineering and Gas Reserves

    • Fluids and fluid types
    • Drive mechanisms
    • Properties of natural gas
    • Material balance
    • Determining gas reserves

    Day one of this course will introduce participants to the basics of gas reservoir engineering.  This will include the following topics, fluid types, drive mechanisms, properties of natural gas, and material balance.  The second half of the day will focus more on gas reserves.  Participants will learn how to determine gas reserves.  Gas volumes and material balance will also be discussed.  The day will end with gas reserve calculations and class exercises.


    Day 2

    Gas Deliverability 

    • Basic gas deliverability
    • Deliverability of gas wells
    • Class exercises

    Participants will begin this day with the basics of gas deliverability.  They will learn about deliverability in wells then go through some class exercises.  During the second half of this day, participants will finish the discussion on deliverability in gas wells along with more class exercises.


    Day 3

    Gas Deliverability Continued and Nodal Analysis 

    • Introduction to nodal analysis
    • Inflow performance for gas wells
    • Outflow or tubing curves
    • Vertical multi-phase flow
    • Production data analysis

    Day three will begin with an introduction to nodal analysis and continue with a discussion on inflow performance of gas wells.  Outflow or tubing curves, vertical multi-phase flow, and production data analysis will also be covered. 

    Day 4

    Well Testing 

    • Introduction to well testing
    • Radial flow and radius of investigation
    • Wellbore storage, damage, and stimulation
    • Introduction to flow and build-up tests
    • Analysis of late-time data
    • Semi-log analysis for gas wells
    • Project assignment
    • Class exercises

    Participants will be introduced to well testing on day four of this course.  Well testing will include a discussion on radial flow and radius of investigation.  Several other topics that will be covered include wellbore storage, damage, simulation, flow and build-up tests, analysis of late-time data, and semi-log analysis for gas wells.  Participants will work class exercises and will receive a project assignment.

    Day 5

    Well Testing Continued and Project Presentations 

    • Modification for gas
    • Manual log analysis
    • Type curve analysis
    • Well test analysis using type curves
    • Flow regimes and the diagnostic plot
    • Project presentations

    On the last day of this course, participants will learn about modification for gas, manual log analysis, and type curve analysis.  The second half of the last day will include well test analysis using type curves, flow regimes, and the Diagnostic Plot.  The day will conclude with participants giving their project presentations.

    Reservoir Engineers, Production Engineers, Laboratory Researchers, and Gas Field Operators.
