Course Overview

This course provides a comprehensive framework for managing conventional and unconventional gas reservoirs. It covers reservoir behavior, pressure maintenance, production optimization, reserves estimation, deliverability forecasting, and integrating reservoir models with economic planning to ensure sustainable and profitable gas field development.

Day-by-Day Outline

Day 1 – Fundamentals of Gas Reservoir Behavior

Properties of dry gas, wet gas, and gas-condensate systems
Real gas behavior and deviation factors
Gas compressibility and material balance
Drive mechanisms in gas reservoirs: depletion, water drive
Exercise: Calculate gas initially in place (GIIP) using material balance

Day 2 – Gas Deliverability and Decline Analysis

Flow regimes in gas wells
Inflow performance relationship (IPR) for gas wells
Single-phase and multiphase flow considerations
Decline curve analysis for gas production forecasting
Workshop: Build deliverability curves and perform decline analysis on gas well data

Day 3 – Pressure Maintenance and Field Development Strategies

Importance of reservoir pressure management in gas fields
Compression and gas recycling strategies
Use of aquifer support and water influx control
Planning infill drilling and optimizing well spacing
Exercise: Design a pressure maintenance plan for a gas reservoir

Day 4 – Advanced Topics: Gas Condensate & Unconventional Gas

Retrograde condensation behavior and its impact on recovery
Modeling condensate banking and strategies for mitigation
Management of tight gas and shale gas reservoirs
Economic considerations in unconventional gas development
Workshop: Analyze production data from a gas-condensate field

Day 5 – Integrated Gas Reservoir Management

Integrating subsurface and surface facility considerations
Linking reservoir forecasts with economic models
Reserves estimation and classification for gas reservoirs
Case studies of successful and challenging gas field developments
Capstone Project: Develop a comprehensive management plan for a conventional or unconventional gas field
