COURSE OVERVIEW:

Core analysis provides the only direct measurement of the physical properties of reservoir rocks, forming the ground truth for all petrophysical and geological models. This course delivers an advanced technical deep dive into the procedures for Conventional Core Analysis (CCA) and Special Core Analysis (SCAL). Participants will explore the journey of a core sample from the wellsite to the laboratory, focusing on the critical methods used to determine porosity, permeability, fluid saturation, and the complex relative permeability and capillary pressure characteristics.

The scope of this training emphasizes the rigorous Quality Control (QC) standards necessary to ensure that laboratory data is representative of the in-situ reservoir conditions. Attendees will learn to identify common sources of error, such as sample damage, mud filtrate invasion, and improper cleaning or drying techniques. We will investigate the physics of core measurement, including X-ray CT scanning, NMR core analysis, and the different methods for determining wettability and its profound impact on oil recovery.

Coverage includes the integration of core data with wireline logs to establish robust rock types and saturation-height functions. By understanding the uncertainties and limitations of laboratory measurements, participants will be better equipped to upscale core results to the reservoir scale. This course is designed for professionals who rely on core data to make high-stakes decisions regarding reservoir quality, reserves estimation, and recovery strategies.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Manage the entire core handling workflow from wellsite recovery to the laboratory.
• Distinguish between the objectives and methods of CCA and SCAL.
• Supervise laboratory procedures for porosity, permeability, and grain density.
• Interpret X-ray CT scans for sample selection and internal heterogeneity analysis.
• Evaluate various core cleaning and drying techniques to preserve rock integrity.
• Analyze relative permeability curves for different fluid systems and wettability states.
• Utilize capillary pressure data to build accurate saturation-height models.
• Perform detailed quality control on all laboratory-reported data points.
• Assess the impact of overburden pressure on core property measurements.
• Determine reservoir wettability using Amott and USBM methods.
• Integrate core-derived rock types with log-based petrophysical facies.
• Use core data to calibrate NMR and dielectric wireline logs.
• Quantify the uncertainty in core measurements and its effect on STOIIP.

TARGET AUDIENCE:

Petrophysicists, Core Analysts, Reservoir Geologists, and Reservoir Engineers who use core data for reservoir modeling and simulation.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
