BTS

The course is designed to give an introduction to the fundamental and practical aspects of modern reservoir simulation. Particular emphasis is placed upon the available data and its integration into a data set that reflects a coherent model of the reservoir. These aspects are reinforced with practical examples. This overview is followed by a detailed discussion of the required input data for a simulation- including rock properties, rock-fluid interactions, and PVT data. Various options for modeling both vertical and horizontal wells are also presented. This section is followed by a discussion of gridding options and the factors which should be considered when choosing a grid. The impact of both grid size and orientation are shown. The key steps to making a successful history match are then discussed and the main concepts illustrated by hands-on exercises. The final section of the course explores the concept of upscaling and the impact it has on full-field modeling.
