This course provides a practical understanding of petroleum systems, useful for integrating geological constraints and rock properties in drilling strategies which ultimately improve drilling models and reduce risk.
Public :
Non-geologists and drilling professionals with no experience in petroleum geology.
Level :Awareness
Prerequisite :
No pre-requisistes are necessary to follow this course.
Course Content
INTRODUCTION TO PETROLEUM GEOLOGY
-
Duration : 2.5 Days
Basin and sedimentary rocks - Petroleum system:
Sedimentary basin - Definitions, structure and terminology.
Sedimentary rocks - Description and main facies - Comparison clastic versus carbonates - Sedimentary process.
Petroleum system - Source rock, reservoir rock and seal rock - Trapping and migration process.
Reservoir engineering: seismic, modeling, accumulations and reserves, effluent behavior, enhanced recovery (EOR), introduction to non-conventional resources and their extraction techniques.
Exercises: interpretation of geological cross section; identification of the petroleum components, petroleum system building; identification of potential prospects and implementation of exploration wells; analysis of limitations and drilling constraints.
FIELD TRIP IN THE PYRENEAN LACQ FIELD (active margin basin)
-
Duration : 2.5 Days
Presentation of the Lacq Basin. Relations with the Pyrenean structure:
Structural overview of the Pyrenean chain. Geomorphology and structural context.
Lacq basin: a petroleum system in the Jurassic, lower cretaceous carbonate domain. Source, reservoir and seal rocks.
Structure of the reservoir, trapping and potential hydrocarbon migration.
Sedimentary study of the upper cretaceous clastic formation:
The turbidites of St-Jean-de-Luz.
Detail of the sedimentary complex. Observation of the clastic deposits. Analysis of the deposit unit in a turbidite system observation and relationship with carbonate series of the Lacq field.
Analysis of the turbidites structure in St Jean de Luz. Syn and post sedimentary structures - Observation of “chair folding”. Dissymmetry of the folding. Notions of pressure/stretching and under compacted zones.
Comparison with turbidities facies of Gan (South of Pau) - Notion of lateral facies variation.
Synthesis and conclusions:
Structural context of the Lacq gas field: an example of active margin basin in foothills domain.
Elements of the petroleum system of the Lacq gas field: an example of petroleum system in carbonate domain.
The upper cretaceous turbidite system: interest of this facies analysis to understand the Pyrenean structure.
Field observation of the turbidite series structure: interest and consequences for drilling purpose.
Learning Objectives
Attendees will be able to implement the following skills:
review main components of a petroleum system, most common facies rocks and their physical properties,
