Petroleum Oil Engineering

Petroleum Oil Engineering Oilfield Calc & Formulas

Petroleum Oil Engineering is a comprehensive field concerned with the activities related to the production of hydrocarbons, which can be either crude oil or natural gas. This app is designed to support the design and development of methods for extracting oil and gas from deposits below the Earth's surface, as well as finding innovative ways to extract resources from older wells.
In the oil and gas industry, exploration and petroleum engineering are the two main subsurface disciplines focusing on maximizing economic recovery from subsurface reservoirs. While geology and geophysics provide a static description of the rock, petroleum engineering focuses on the estimation of recoverable volume using a detailed understanding of the physical behavior of oil, water, and gas within porous rock at very high pressure.
This app serves as a vital technical bridge, combining knowledge of geophysics, petroleum geology, formation evaluation, and reservoir simulation into one powerful mobile tool.
