An Interactive 5-Day Training Course
Reservoir Quality Analysis of Sandstone & Carbonate Rock Types
Course Overview
This GLOMACS training course is aimed at giving oil industry geologists a detailed introduction to the study of sandstone and carbonate rock-types in terms of reservoir quality. Reservoir quality analysis permits to identify the main depositional, provenance and diagenetic controls on the evolution of the poro-perm characteristics of sandstone and carbonate reservoirs (e.g. evolution of porosity vs. burial depth, mineralogical content and diagenetic environments). Examples from sandstone and carbonate oil/gas reservoirs (i.e. current East & West Africa basins) are also taken into consideration.
This training course will highlight:
- Introduction to siliciclastic and carbonate reservoirs with emphasis on controls on reservoir quality
- Sandstone composition, provenance, diagenesis, and tectonic settings
- Carbonate composition (allochems, orthochems), classification and diagenesis
- Petrographic analyses (TS, SEM, CL), XRD, QEMSCAN and integration of reservoir quality results
- Porosity classification, porosity evolution vs. burial depth, stratigraphy, composition, authigenic components and diagenetic phases/environments
- Concept of rock typing, rock typing schemes and rock typing analysis of uncored reservoir intervals (sandstone and carbonate cuttings tied to wireline logs)
Training Objectives
By the end of this training course, participants will:
- Understand what are the different types of sandstone hydrocarbon reservoirs and their main controls on reservoir quality
- Understand what are the different types of carbonate reservoirs and their main controls on reservoir quality
- Be able to differentiate depositional, provenance and diagenetic markers of analysed sandstones and carbonates
- Be able to integrate and interpret poro-perm data vs. stratigraphy and regional geology (e.g. well correlations)
- Understand the main rock-based methodologies of analysis applied to reservoir quality studies
- Be conversant with the concepts of Rock typing and petrophysical comparison of cuttings and core samples
Who should Attend?
This training course is suitable to a wide range of professionals but will greatly benefit:
- Sedimentary geologists of service and oil companies
- Junior to mid-level geologists carrying out rock-based geological projects
- Sedimentologists who need to be conversant on rock typing concepts
- Petrographers of small and large oil-industry organizations
- PhD students in sedimentary geology of academic institutions
