Geological field trip to the Ainsa area in the Spanish Pyrenees

The course is primarily about clastic reservoir geology. Although the rocks studied are not commercial reservoirs, they are analogous to a number of important reservoir sections offshore Norway and other parts of the world, and the use of analogues will be discussed throughout the course. Within the topic of reservoir geology a number of parallel themes will be addressed. Many of these will run between outcrop localities and between days. The main themes are:

1. Fluvial systems as reservoirs
2. Clastic shallow marine systems as reservoirs
3. Deep marine systems as reservoirs
4. Introduction to techniques in reservoir modelling
5. Geology of the Pyrenean Foreland Basin

The course will include a mixture of fieldwork and class work. The aims of the fieldwork are to illustrate the concepts that are utilized to build reservoir models and provide hands-on experience at building the models.

Open for both PhD and Master students. Interested students should send an application and academic CV to with a short motivation for participation. NFiP will pay the course fee for approved applications.

Course Dates: Nov 14-18, 2016

Registration closed

You will be divided into 4 groups for the duration of the course. Each morning one of the groups will have a short presentation on the previous day fieldwork. In addition, an individual report/best practice document for reservoir modelling of different reservoir types. The reports must be submitted by the end of the year.
