Part of a four-volume set, this book constitutes the refereed proceedings of the 7th International Conference on Computational Science, ICCS 2007, held in Beijing, China in May 2007. The papers cover a large volume of topics in computational science and related areas, from multiscale physics to wireless networks, and from graph theory to tools for program development.

This proceedings book gathers selected papers that were submitted to the 2020 International Conference on Comprehensible Science (ICCS 2020) that aims to make available the discussion and the publication of papers on all aspects of single and multi-disciplinary research on Conference topics. ICCS 2020 held on October 30–31, 2020. An important characteristic feature of Conference is the short publication time and world-wide distribution. Written by respected researchers, the book covers a range of innovative topics related to: Big Data & Data Mining; Business, Finance & Accounting & Statistics; COVID-19 Impact; Educational Technologies; Innovative Applied Sciences; Innovative Economics; Management Technologies & Systems; Media Technologies; Physical & Material Sciences; Medicine, Public Health & Rehabilitation. This book is useful for private and professional non-commercial research and classroom use (e.g. sharing the contribution by mail or in hard copy form with research colleagues for their professional non-commercial research and classroom use); for use in presentations or handouts for any level students, researchers, etc.; for the further development of authors’ scientific career (e.g. by citing and attaching contributions to job or grant application).

The use of numerical reservoir simulation with high-speed electronic computers has gained wide acceptance throughout the petroleum industry for making engineering studies of a wide variety of oil and gas reservoirs throughout the world. These reservoir simulators have been designed for use by reservoir engineers who possess little or no background in the numerical mathematics upon which they are based. In spite of the efforts to improve numerical methods to make reservoir simulators as reliable, efficient, and automatic as possible, the user of a simulator is faced with a myriad of decisions that have nothing to do with the problem to be solved. This book combines a review of some basic reservoir mechanics with the derivation of the differential equations that reservoir simulators are designed to solve.
