Monitoring or surveillance of reservoir fluids during the producing life of a field and mapping of oil–water and gas–oil interface are necessary for understanding the fluid dynamics.
Various types of well logs measure different properties in the well. Analysis of the data determines the volume of hydrocarbons present in a reservoir, and its potential to flow through the reservoir rock into the wellbore.
... oil and natural gas reservoirs. Based on rule of thumb or analogy with another reservoir or reservoirs believed to be similar. From EIA (1998). several areas. The following are just a couple of examples of the applicable areas in ...
Geophysics for Petroleum Engineers: Chapter 1. Introduction
Geophysical techniques apply the principles of physics for study of physical responses of rocks under passive or active perturbation.
