Report - Essay Example According to many experts, permeable and porous reservoir rocks are normally the primary basis for the presence of petroleum gas or oil as well as the extent to which these important resources can be effectively produced. In its simplest form, analysis of reservoirs normally involves a critical assessment of their porosity to help calculate the potential volume of hydrocarbons as well as the permeability to help calculate how easily the hydrocarbons are likely to flow out of the rocks (Rousel-Houston, 2008). This paper critically describes the reservoir geology with particular focus to its significance in the mining of naturally occurring hydrocarbons such as natural gas and crude oil that are usually trapped below the overlying rock formations with lower permeability or porosity. There are a diverse number of reasons why the understanding of reservoir geology is critically important particularly for oil and gads engineers. For example, engineers require developing a 3- D conceptual model of the reservoirs to facilitate efficient extraction of the hydrocarbons. Additionally, the conceptual model helps in the decision-making process in selecting perforations and forecasting production. On the other hand, many of the engineering measurements currently being used on reservoirs have little spatial information. For instance, core measurements do not usually have any dimensional information and continuous core measurements and wireline logs are only 1 dimensional. However, geologic information contains critically valuable spatial data that helps in visualizing the reservoir in 3-D. In this regard, knowledge of reservoir geology is critically important because to oil and gas engineers because it enables them to understand important geological data that not only improves their conceptualization of the reservoir but also their engineering
