Conducting an Integrated Reservoir Study

Introduction

• Course Introduction
• Static Modeling
• Structural Framework
• Stratigraphic Framework

After a brief introduction to set the overall course objectives, participants will learn why 3D static modeling is important, reservoir characterization workflow, heterogeneity. Elements of structural framework modeling, such as Plate tectonics, forces and stresses, major structural components for hydrocarbon trapping like folding, faulting and fracturing will be covered.  Elements of the stratigraphic framework, such as terminology, well log correlation, mapping and contouring, cross-sections and scaling, will also be covered.

Facies Modeling

• Depositional Systems
• Pore Systems
• Petrophysics

The day will cover the principal components of reservoir facies modeling, as replated to depositional and pore systems. Facies definition and types, reservoir flow units, clastic and carbonate sedimentary environments will be discussed under depositional systems. Pore system components, clastic and carbonate rock classifications, influence of clays, diagenesis and geologic factors affecting reservoir quality will be discussed under pore systems. The day will conclude with the petrophysical aspects of property modeling, such as quantification of hydrocarbons, study steps, acquisition of borehole data (wireline, mudlogging, core), basic measurements, log interpretation and petrophysical data integration.

(morning) Property Modeling

• Geophysics
• Property modeling methods 

On the morning of day 3 participants will learn the geophysical aspects of property modeling, such as seismic principles, land and marine acquisition, borehole seismic (VSP), interpretation and prediction of reservoir properties, seismic attributes, log to seismic tie and time lapse seismic.  The final morning session will conclude with the Geoscience portion of the course, and will focus on the practical aspects of building the static model, such as structural and stratigraphic framework, property modeling, deterministic and stochastic approaches for property distribution (with a special section on geostatistics), risk and uncertainty, and upscaling for the dynamic model.

(afternoon) Introduction to Dynamic Modeling

• PVT Properties
• Capillary Pressure and Relative Permeability
• Reservoir Drive Mechanisms

Afternoon of day 3 will cover key concepts such as PVT, capillary pressure, and fluid distribution.  The day will conclude with discussion on reservoir drive mechanisms.

Dynamic Reservoir Model 

• Upscaling
• Dynamic Model Initialization
• Building the dynamic reservoir model

The fourth day will begin defining upscaling, need for upscaling and upscaling methods. Event histories, initializing pressure, and production data will also be covered.  The day will end with participants learning how to build the dynamic reservoir model. 

Performance Forecasting and Economic Modeling

• Performance forecasting
• Reservoir optimization
• Economic modeling

On the last day of this course, participants will learn about dynamic model calibration and history matching, how to forecast reservoir performance. Participants will also learn about the transition from history to forecast sensitivity analysis.   The last part of the day will include the key concepts of optimizing reservoir development. and a plan for reservoir development.
