Kwanza Basin Clastic Sedimentology (Angola)

This course is for any geoscientist with a basic knowledge of geology, and any participant at bachelor or master level. Participants must be in good health and physical conditions to attend.

This course is designed to fit an appropriate time schedule and to maximize the HSE requirements. It has been simplified. Upon specific request, we can provide a more complete agenda fitting your requirements.

1. Review of the fundamentals of silico-clastic sedimentation (environments processes, facies, rock descriptions, 3D reservoirs geometries & heterogeneities)
2. Present-day and ancient depositional models and analogues description using field analysis techniques and core workshop interpretations
3. Integration in regional geology and global stratigraphic context, within a multi-scale approach (from hand samples, to logs, outcrops & seismic data)

A highly participative learning approach is applied during the training session. All participants will have to suggest solutions and share their interpretation with others.

Each participant is required to provide a yearly medical certificate. A pre-field-trip HSE analysis is compulsory before any session.

All kinds of classic deposits will be studied: fluvial, eolian, deltaic, littoral wave or tide dominated, turbidites, injectites and contourites.

Overview of clastic sedimentation, Siliciclastics in the Angolan context

• From Satellite imagery
• From Zaiango project database

The day-1 knowledge will be applied to fluvio-deltaic outcrops of the Paleo-Kwanza river from Bom Jesus to Miradouro da Lua.

Outcropping strata along the coast, from Cabo Ledo to Sangano, will give another opportunity to illustrate turbiditic facies, sequences, geometries and reservoirs heterogeneities.

Sandy barriers and their lagoonal parts are key elements of Angolan oil history. The Mussulo lagoon (littoral & tidal bars and channels) will be studied on foot and by boat.

A core workshop will help participants to match field observations with theoretical knowledge and nomenclatures.
