    Eclipse Blackoil Reservoir Simulation

    The Eclipse industry-reference Blackoil simulator offers the most complete and robust set of numerical solutions for fast and accurate prediction of dynamic behavior—for all types of reservoirs and degrees of complexity, structure, geology, fluids, and development schemes. Eclipse is a fully implicit, three-phase, 3D, general purpose black-oil simulator that includes several advanced and unique features. In this course, you will discover the various solutions Eclipse offers over the entire spectrum of reservoir simulation.

    During this course, you become acquainted with the basic features and keywords of the Eclipse Blackoil simulator. An overview of the input data and file handling characteristics is followed by a presentation of each section of the input data and a practical exercise. The exercises allow you to construct a simulation model from scratch.

    After you construct the model, you match the simulated past production to the measured production and future recovery optimization by simulating several production scenarios.

    The course incorporates instruction in the use of the Petrel* Reservoir Engineering (RE) pre- and post-processor (part of the Petrel E&P software platform) as an integral part and the relationship between Eclipse and Petrel RE is explained.
