An analysis for oil reservoir is the analysis of a reservoir’s oil content. For oil, the main constituents are oil and water; together with gases and vapors. The aim of an oil reservoir study is to identify and measure the physical, optical, and chemical properties of the oil within the reservoir, thus obtaining data on its physical stability and suitability as fuel or business chemicals. It is done by several methods including drilling, geophysical, or geochemical techniques.
drilled holes are used to detect oil reservoirs. Geophysical investigation requires drilling into the reservoir to expose the top of the reservoir wall or other penetrations. Optical or Electron Microscopy is used to inspect for and evaluate fractures, discontinuities, or geospatial structure.
An oil reservoir analysis can be used to characterize the oil layer thicknesses and rate of precipitation within the reservoir. There are also applications that analyze for oil and gas composition. Analysis for oil and gas contaminants may be performed on well bores, exploratory wells, or surface wells. Gas analysis may be performed on reservoir heads, on train wrecks, or on inland waters. Other methods include subsurface or surface testing, which may also be conducted on well bores, exploratory wells, or surface wells.
Analysis for oil reservoirs must not only be performed on the reservoir top, but also below the earth’s surface. There are three main ways to drill into the ground for oil. The first is known as the active hole drilling. In this method, a shaft is inserted into the earth at the well site, which creates an opening large enough to allow drilling into the ground. The second method is known as the passive hole drilling, which does not require a shaft to open up into the earth; the drilling is done by using the soil or rock as a platform.
One reservoir analysis method that requires little equipment is the geothermal study. In this method, the temperature of the surrounding area is measured and recorded during the day, then the same data is taken at night. The difference between the measurements is used to determine the temperature of the underground oil reservoir. The third method, known as the seismic surveying, determines the movement and intensity of earthquakes in an area by taking sound waves from the surface of the earth. With the help of these techniques, scientists and engineers can predict the rate and intensity of seismic activity, which can help in emergency response and natural resource management.
Oil reservoirs can be exploited for economic purposes; however, over time, their productivity can wane due to changing climate conditions. It is very important for an investor to know the reservoir’s productivity so that he can adjust his plans accordingly. Producers must also learn how to drill safely, according to the guidelines set by Oil and Gas International. Drilling for oil can be very dangerous if the drilling process goes wrong. Thus, drilling companies use experts and various technologies to prevent accidents.
An important part of analyzing for oil reserves is the geophysical study. In this technique, data such as soil texture, topography and other features are obtained from samples of earth and rocks. The study of soil textures gives important clues on the reservoir’s water content, thickness, permeability, porosity and strata composition. This information can help determine the quantity and quality of gas or oil within the reservoir. Geologists also study the rate of precipitation and temperature variations at various places to find out if there is enough oil reserve to explore.
There are many more methods for analyzing for oil reserves including geochemistry, reservoir modeling, structural geometry, and transport modeling among others. These techniques can be used together or independently to arrive at the best solutions for oil problems. Although there is still a lot of work to be done in studying for oil reserves, using these methods will greatly help engineers and geologists plan for future exploration and extraction of natural resources.
