The most up-to-date practices, processes, and technologies for petroleum reservoir simulation.


Audience
Petroleum, drilling, and reservoir engineers, production engineers and geologists

Description





Petroleum forms in underground reservoirs, whether on land or offshore, and it is the job of the reservoir engineer, geologist, or petroleum engineer to figure out the best method for the drilling engineers to get the crude oil out of the ground in the most efficient way possible. Until reservoir simulation software came along, in the last several decades, the only way to do this was to drill multiple test wells where it was thought there was oil or gas and hope to hit the reservoir.



Now, simulation software is widely available, and, though simulation is much more accurate than it used to be, it is still a very difficult technology to master and navigate, and software packages are all different, with different shades of accuracy.



This book helps the engineer or geologist use the right engineering equations and scientific methods to cut down on mistakes and boost the accuracy of simulations. The authors clarify the underlying mathematics and physics behind reservoir simulation and makes it easy to have a range of simulation results along with their respective probability. This makes the risk analysis based on knowledge rather than guess work.



This new treatment on reservoir simulation is by far the strongest tool for engineers and managers to back up reservoir simulation predictions with real science, adding transparency and ease to the process of reservoir simulation in way never witnessed before. Finally, No other book provided readers complete access to the 3D, 3-phase reservoir simulation code, available for download from www.scrivenerpublishing.com.
