COURSE OVERVIEW:

Core to Log Integration and Rock Typing Workflows is a highly technical course focused on reconciling the high-resolution direct measurements from physical rock samples with the continuous, indirect measurements provided by wireline logs. This course provides the rigorous methodology required to upscale petrographic and petrophysical core data to the reservoir scale. By establishing a robust link between "ground truth" core observations and log signatures, participants can build more reliable geological models that accurately represent subsurface heterogeneity.

The scope of this training involves the detailed alignment of core and log depths, the calibration of log-derived porosity and saturation to core standards, and the implementation of advanced rock-typing schemes. Participants will explore various statistical and deterministic methods for defining Petrophysical Rock Types (PRT) and Hydraulic Flow Units (HFU). The course emphasizes the importance of understanding pore-throat distributions and capillary pressure characteristics to define the flow behavior and storage capacity of different rock units.

Furthermore, the course addresses the practical application of these workflows in multi-well studies and field development planning. Participants will learn how to use supervised and unsupervised machine learning techniques to propagate core-defined rock types into un-cored intervals and neighboring wells. This integrated approach ensures that the static reservoir model is honors the underlying physics of fluid flow, leading to more accurate production forecasts and optimized well placement strategies.

COURSE OBJECTIVES:

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

• Perform accurate depth matching between core samples and wireline logs.
• Calibrate log-derived porosity and density to Routine Core Analysis (RCA) data.
• Identify and correct for core compaction and expansion effects.
• Utilize thin-section petrography to validate log-based mineralogy models.
• Classify reservoirs into Hydraulic Flow Units (HFU) using the FZI method.
• Integrate Mercury Injection Capillary Pressure (MICP) into rock typing.
• Develop robust permeability predictors using core-log regression analysis.
• Apply the Winland R35 and Pittman methods for pore-throat characterization.
• Utilize borehole images to extend core-scale features to the well scale.
• Propagate rock types into non-cored wells using clustering algorithms.
• Evaluate the impact of rock types on saturation-height modeling.
• Quantify the uncertainty associated with upscaling core data to logs.
• Create integrated "Master Logs" that synthesize core and log interpretations.

TARGET AUDIENCE:

Petrophysicists, Reservoir Geologists, Core Analysts, and Geomodellers responsible for reservoir characterization and property population.

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.
