DE0802 : Core Analysis for Reservoir Characterization

 

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops. 

More than three-quarters of current additions to the world's reserves come from better management of existing reserves. Core-based measurements offer the most tangible and direct means of determining critical reservoir parameters. Core analysis can play a vital role in field equity or unitization and is often considered to be the ground truth to which other measurements are compared (e.g., wireline logging). Evidence of hydrocarbon presence, reservoir storage capacity, and flow capacity along with the distribution of porosity, permeability, and geological descriptive information can be directly obtained from core material. 

 

Core analysis is the fundamental foundation of reservoir characterization. Using a multidisciplinary approach, managerial, drilling, geological, and engineering requirements should all be considered. Design and application of core analysis is dependent on the coring method, the coring fluid systems, core handling at the wellsite, and core preservation techniques. Core analysis provides the building blocks for understanding fluid flow, ultimate recovery, and displacement efficiencies. Over 30 percent of the classroom time will be dedicated to data analysis, workshops, and case studies. 

 

This course is designed to provide and up-to-date overview on core analysis for reservoir characterization. It covers the core analysis value and the coring process; the sample preparation and basic data acquisition (routine core analysis); the rock properties used in reservoir modelling and reservoir simulation models; the pre-screening of material both whole core and samples for SCAL testing; the interpretation and validation of SCAL report; and reviewing a quality control process. 

 

By the end of the course, participants will be able to design a SCAL program with regard to the given objectives; apply all the standard SCAL techniques that covers the electrical properties, capillary pressure, NMR, relative permeability and wettability; and illustrate data quality control and interpretation including the integration of petrophysical results.
