Canyon and Slope-channel Systems: Analogues for the West African Margin (Brushy Canyon Formation, Southeast New Mexico and West Texas)
The course will examine the depositional facies and stratal geometries developed in deepwater slope and channel environments.
Description
This field course is designed for geoscientists and engineers exploring and developing deepwater clastic reservoirs with a particular focus on analogues for the West African margin. The course will examine the depositional facies and stratal geometries developed in deepwater slope and channel environments and the controls on reservoir presence and quality.
Duration and Logistics
A five-day field course beginning and ending in El Paso, Texas. Most training will take place through observation and discussion in the field.

Exertion Level
This class requires a DIFFICULT exertion level. Fieldwork is in west Texas and southeast New Mexico, where the weather is arid and usually hot, although cold and wet weather is possible in the spring and fall, when daily temperatures range from 5–25°C (40–80°F). The course includes a hike of around 10 km/6 miles with an ascent of 500m (1600 ft), and shorter hikes, frequently over very steep and uneven ground. Transport on the course will be by coach. Most of the driving is on black-top roads, with some driving on graded dirt roads.
Objectives
You will learn to:
- Comprehend the relative incisional nature of canyon and slope channel-complexes, their aspect-ratios and how they correspond to slope position.
- Understand channel-complex hierarchical terminology, stacking patterns and implications for reservoir connectivity.
- Appreciate different deep-water facies types, their distribution and reservoir characteristics within different architectural elements.
- Realize the complex distribution & variability of thin-beds in deep-water systems and the significance of their non-unique interpretations.
Level and Audience
Intermediate. The course is aimed at geoscientists, petrophysicists, reservoir engineers and production engineers working deepwater clastic reservoirs, particularly those from the Western Africa margin.
