N950 Applied Reservoir Simulation
N950 Applied Reservoir Simulation
This course is an overview of reservoir simulation concepts and assumptions and discusses data selection, preparation and integration; the strengths and weaknesses of various types of models and modelling strategies; the computing environment and the steps required to create a credible model. The concepts will be illustrated via ECLIPSE software, but the concepts are applicable to other simulation packages.
This is a five-day classroom course comprising lectures and hands-on simulation activities (approximately 50/50 ratio). Participants will be provided a basic geologic description, basic fluid descriptions, relative permeabilities, capillary pressure data, initial conditions, and historical rate data. These data will be input into the simulator with minimal reformatting, where participants will perform a history matching exercise. The simulation result will be compared to historical data and with results from others in the class, thus highlighting how different input assumptions can affect the simulation results.
Participants will learn to:
1. Formulate concepts in order to justify, propose and design reservoir simulation models.
2. Develop simulation data requirements and assemble appropriate data.
3. Compose data preparation guidelines and synthesise / integrate dynamic data to create data files for reservoir models.
4. Formulate production data for integration with the reservoir simulation process.
5. Evaluate model outcomes and adjust data in order to enhance history matches and generate forecasts for selected development options.
6. Assemble and use simulation results for reservoir evaluation and study documentation.
The workshop begins with an overview of general reservoir simulation concepts and assumptions, followed by a discussion of data preparation and history matching techniques. Significant time will be allocated for hands-on application of the simulator. Topics of discussion include introduction to reservoir simulation, introduction to ECLIPSE, grids, aquifers, PVT data, rock and fluid data, initial conditions, and time-dependent data. The class builds upon a single example simulation which applies many of the most common elements of a simulation study. The class will not use all the auxiliary tools for preparing simulation data (e.g. 3D geomodels, PVT programs or vertical-flow performance analysis). However, the application of such software in the simulation workflow will be discussed. The specific software to be used will be Eclipse black-oil for simulations, Eclipse Office for xy plotting, and Floviz for 3D visualization. Third party visualization software such as, S3GRAF or TECPLOT RS, may also be used depending on license availability.
The course will generally follow the basic outline shown here, but all the material may not be covered in detail depending on the level of experience of the participants with the ECLIPSE software. The order of presentation of the material is subject to change, depending on the level of student familiarity with the various topics.

This workshop is intended for individuals who use ECLIPSE or similar software for reservoir simulation studies. Participants are assumed to have some background in simulation concepts and in running basic simulation models. Prior experience using ECLIPSE or a similar simulator is required.
Whilst there is no formal prerequisite for this class, participants are expected to have a basic understanding of reservoir modelling simulations.
N961 (Strategic Reservoir Simulation), delivered in Europe, covers similar reservoir simulation topics.
Nautilus also offers a number of classroom and field courses on building reservoir models, including N058 (Reservoir Characterisation and Geostatistical Modelling in Field Development), N345 (Geomodeling for Unconventional Reservoirs) and N012 (Reservoir Modelling Field Class (Utah, USA)).
