Natural Gas Reservoir Engineering

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.

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.

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. 

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.

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.
