This course provides a comprehensive and practical understanding of methods, procedures and issues related to laboratory conventional and special core analysis for describing and evaluating reservoir rock properties, and all considerations that should be taken into account for reservoir characterization.
Geoscientists, petrophysicists, reservoir engineers, petroleum engineers and other E&P professionals willing to deepen their knowledge in conventional and special core analysis.
Degree in geology, petroleum engineering or reservoir engineering, or equivalent experience, with basic knowledge in core analysis.
CORING & CORE ANALYSIS
Business value of core analysis demonstrated on real life examples.
Necessary quality procedures at the start of a measurement program.
Coring methods (conventional vs. pressure coring, decompression during tripping).
Representative wettability (fresh vs. restored state).
Conventional and Special Core Analysis (SCAL).
GENERALITIES ON TWO-PHASE FLOW PROPERTIES
Darcy’s law for two phases, relative permeability.
Wettability (Amott and USBM methods).
Impact of wettability on relative permeability and capillary pressure.
Basics of JBN analysis for the UnSteady-State experiment.
Effect of capillary pressure demonstrated by hands-on simulation, using the SCORES SCAL simulator.
CONVENTIONAL CORE ANALYSIS
Porosity definition and measurement.
Permeability (absolute) definition and measurements.
Formation factor and Resistivity Index definition and measurement.
Mercury injection (MICP) for reservoir saturation height function and pore size distribution.
Recent developments in MICP showing important problems in MICP for low permeability rock when assessing transition zones.
SPECIAL CORE ANALYSIS (SCAL), MEASUREMENTS OF SCAL PROPERTIES
Overview of measurement methods and data interpretation for relative permeability and capillary pressure.
Analysis of centrifuge data using Hassler-Brunner, Forbes methods.
Analysis of centrifuge data using Hagoort method.
Effect of relative permeability on capillary pressure measurement demonstrated by hands-on simulations using the SCORES SCAL simulator.
QUALITY CONTROL OF AVAILABLE DATA
Sample selection using X-ray CT for homogeneity assessment.
