In recent decades, Reservoir engineering has been the subject of increasing interest by researchers, academics and professionals from various fields. The impact of Reservoir engineering on modern society is undeniable, its implications range from the economic to the cultural sphere, including the fields of health and technology. In this article, we will explore the various facets of Reservoir engineering and analyze its influence on different aspects of our daily lives. From its role in the formation of identities to its participation in the development of business strategies, Reservoir engineering has become a relevant topic that deserves to be examined from multiple perspectives. Through the analysis of Reservoir engineering, we seek to shed light on its implications and unravel its complexity, in order to better understand its role in the contemporary world.

Reservoir engineering is a branch of petroleum engineering that applies scientific principles to the fluid flow through a porous medium during the development and production of oil and gas reservoirs so as to obtain a high economic recovery. The working tools of the reservoir engineer are subsurface geology, applied mathematics, and the basic laws of physics and chemistry governing the behavior of liquid and vapor phases of crude oil, natural gas, and water in reservoir rock. Of particular interest to reservoir engineers is generating accurate reserves estimates for use in financial reporting to the SEC and other regulatory bodies. Other job responsibilities include numerical reservoir modeling, production forecasting, well testing, well drilling and workover planning, economic modeling, and PVT analysis of reservoir fluids. Reservoir engineers also play a critical role in field development planning, recommending appropriate and cost-effective reservoir depletion schemes such as waterflooding or gas injection to maximize hydrocarbon recovery. Due to legislative changes in many hydrocarbon-producing countries, they are also involved in the design and implementation of carbon sequestration projects in order to minimise the emission of greenhouse gases.
Reservoir engineers often specialize in two areas:
The dynamic model combines the static model, pressure- and saturation-dependent properties, well locations and geometries, as well as the facilities layout to calculate the pressure/saturation distribution into the reservoir, and the production profiles vs. time.
