Example Delivery Outline (This course can be customized to fit the expectations of the participants):
1. Course Expectations
2. Discssion on Why Capillary Pressure Is Important......
Chapter 1 - Pore Geometry and Wettability
1. Using Petropgraphic Thin-Sections to Explore Pore-Geometry
2. Using Scanning Electron Microscopic Images to Explore Pore-Geometry
3. Using Lab Methods to Explore Pore Geometry
4. Workshop 1 - Basic Pore Geometry
On the first day participants will learn the importance of capillary pressure and its practical applications. Pore geometry will be discussed using petrographic thin-sections and SEM methods. Wettability will be in introduced and the day will end with a practical pore geometry workshop.
Chapter 2 - Introduction To Drainage and Imibibition
1. Applications of Drainage Capillary Pressure Analysis (Contacts and FWL)
2. Applications of Imibibition Capillary Pressure Analysis (Production Trends and Residual Saturation)
Chapter 3 - Lab Methods to Determine Capillary Pressure
Day 2 will focus on the drainiage and imibiibition processes associated with establishing fluid saturations. Practical applications of determining the free water level (FWL) and immisicible fluid-contacts will be discuseed and demonstrated by using workshops and example. Common laboratory methods will also be addressed.
1. Porous Plate Method
2. Centrifuge Method
3. High Pressure Mercury Injection
Chapter 4 - Determining Pore Throat Radius from Lab Data and Estimating Pore Throat Radius from k and phi
Day 3 will cover more specific information concerning lab methods and data acquisition. Common lab data analysis will focus on lab-based pore throat radius and techniques to predict pore throat radius from porosity and permeability. Participants will complete a detailed workshop using these techniques.
Chapter 5 - Converting from lab data to height above free water
Chapter 6 - Common Applications (Thomeer and Leverett J)
Chapter 7 - Introduction to Petrophysical Rock Types
Day 4 will cover show how to convert lab measured capillary pressure data to reservoir conditions to determine height above free water, seal capacity and initial water saturation. Petrophysical rock types will be determined from high pressure mercury injection porosimetry data using semi-log, cartesian and incremental saturation intrusion plots combined with several other quality control data analysis graphs. Participants will complete a detailed workshop using these techniques.
Chapter 8 - Applied Saturation Height Model Using Petrophysical Rock Types
Well Analysis and Reservoir Evaluation Workshop
Chapter 9 - NMR and Core-Log Integration
Day 5 will cover show how to create a customized saturation height capillary model based on petrophysical rock types. The SHM can be based on Leverett, Gunter/Smart or a Modified Thomeer method.
