Modern Production Data Analysis for Unconventional Reservoirs

Who Should Attend: Engineers and technologists involved in the exploitation, production and evaluation of tight and unconventional reservoirs.

General Notes: 2 Day Course. Basic Windows navigation skills are recommended. Participants are encouraged to bring a laptop and their own data as time will be allotted to go through several class examples. Software will be provided.

Course Objectives:

To provide a comprehensive methodology for well performance analysis, with specific focus on unconventional oil and gas. The approach combines the use of several powerful techniques. Participants will learn how to:

Critically assess data quality and perform qualitative diagnostics on well production data
Identify well and reservoir flow regimes from rate / pressure response
Estimate reserves, OGIP/OOIP and drainage area
Determine "linear flow parameter" and skin
Forecast production, with particular focus on the inherent uncertainty in unconventional plays
Assess well performance and identify optimization candidates

To illustrate the practical aspects of production data analysis using real examples

Course Topics:

An Introduction to Well Performance Analysis
Linear Flow Analysis for Tight Fractured Reservoirs
Simplified Approach

Log-log diagnostic plot – Identifying flow regimes
Specialized plot – Determining LFP and skin
Flowing Material Balance Analysis – Determining SRV
Modified Hyperbolic Decline Curves

History Matching Using Analytical and Numerical Models

Modeling Performance of Hz Wells with Multiple Fractures
Inclusion of Pressure Dependent Permeability
Inclusion of Adsorbed Gas

Examples

Depending on time and interest, examples from Barnett, Bakken, Montney, Horn River, Marcellus, Haynesville and Eagle Ford plays will be presented
Examples provided by course attendees will be worked through as a class
