COURSE OVERVIEW:

Carbonate Diagenesis and Reservoir Quality Prediction is a specialized course focusing on the post-depositional physical and chemical changes that transform carbonate sediments into complex reservoir rocks. Unlike siliciclastics, carbonate reservoirs are highly susceptible to diagenetic alterations that can either enhance porosity through dissolution and dolomitization or destroy it through cementation and compaction. This course provides geoscientists with a process-based framework for predicting where these high-quality "sweet spots" are likely to occur in the subsurface.

The scope of this training covers the entire diagenetic spectrum, from the marine-eogenetic environment to deep burial and telogenetic uplift. Participants will explore the geochemistry of carbonate waters and the kinetics of mineral stabilization, focusing on the transition from metastable aragonite to stable calcite and dolomite. By integrating petrographic analysis with isotope geochemistry and fluid inclusion data, participants will learn to reconstruct the paragenetic sequence and its impact on the evolution of pore systems over geological time.

Furthermore, the course addresses the quantitative prediction of reservoir quality through the integration of sequence stratigraphy and diagenetic modeling. Participants will learn how sea-level fluctuations drive fluid migration patterns, such as meteoric flushing or hydrothermal circulation, which are the primary controls on diagenetic facies. This integrated approach allows exploration and development teams to move beyond simple depositional models and build more accurate static reservoir models that account for the extreme heterogeneity typical of carbonate systems.

COURSE OBJECTIVES:

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

• Define the primary diagenetic environments: Marine, Meteoric, and Burial.
• Identify key carbonate minerals and their stability in different fluid regimes.
• Recognize diagenetic textures in thin sections, such as cements, neomorphism, and compaction.
• Evaluate the impact of dolomitization on porosity and permeability development.
• Differentiate between early-stage and late-stage diagenetic events.
• Utilize stable isotopes (Oxygen and Carbon) to interpret diagenetic fluid origins.
• Predict the occurrence of karst and dissolution features using sequence stratigraphy.
• Analyze the role of mechanical and chemical compaction in reservoir degradation.
• Construct a paragenetic sequence for a given carbonate reservoir interval.
• Integrate diagenetic trends into 3D static reservoir models.
• Assess the influence of hydrothermal fluids on deep carbonate porosity.
• Relate pore-throat geometry to diagenetic history and rock-typing.
• Apply diagenetic models to de-risk reservoir quality in exploration prospects.

TARGET AUDIENCE:

Carbonate Sedimentologists, Petrophysicists, Reservoir Geologists, and Core Analysts are involved in the characterization of limestone and dolomite reservoirs.

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.
