There are many different methods of analysis for oil shale wastes and gas retort wastes. These methods have been developed to help the oil and gas industry to determine the suitability of different waste streams for a variety of uses. They are also designed to help ensure that all sources of waste are effectively disposed of and to help prevent further environmental damage.
A comprehensive analysis of oil shale wastes and gases is the only way to accurately evaluate what the waste can be used for. This includes determining if the waste can be used for creating energy or to provide a natural resource that will be useful in the future. Different wastes will require different analysis methods depending on their purpose. Some waste streams will require complete analysis to determine their suitability for either energy production or as a source of natural resources, while other wastes can be evaluated more closely in a limited amount of time and with less effort.
Wastes produced from oil drilling can be examined under several different methods to determine the nature and extent of contamination. The first method of analysis is laboratory testing, which tests for the presence of petroleum byproducts. The testing method is based on a chemical process that uses a sample of a crude oil stream to identify any petroleum residues. The samples are then analyzed under an analytical microscope to determine the amount of petroleum residue present. The method is best used for analyzing the chemical properties of the petroleum stream and for determining its potential for hydrocarbon exploitation.
Oil shale wastes that contain crude oils can be analyzed under a different method known as surface water discharges testing. In this method, samples of water that have discharged from the oil field are tested to determine if it contains hydrocarbons. These tests can be performed on land or a water body and the water must have discharged from within a few hundred meters of the oil field. The methods used in this method are similar to those used in surface water testing, but this type of discharges is conducted under laboratory conditions to determine the hydrocarbons contained in the water.
The third method of analysis for oil and gas is known as hydraulic, static testing. This method of testing for the characteristics and chemical compositions of oils and gases is performed on the surface of the reservoir. As the reservoir fills with water, the hydrocarbons in the reservoir are forced to rise to the top of the reservoir by gravity. As the reservoir fills with water, the hydrocarbons settle and are forced back into the reservoir where they are monitored for their chemical composition, density, viscosity, and other characteristics.
Gas analysis is another common method of analyzing oil and gas for the purposes of making gas and oil. Gas analyzers are used to analyze gas streams for chemical constituents, their density and their boiling points.
Analyzing oil shale and gas using laboratory techniques is often combined with surface water discharges testing in order to determine the hydrocarbon distribution. Gas analyzers also include a procedure called carbon electrode analysis to determine the exact proportions of various hydrocarbons in the gases. These gases are analyzed by spectroscopy and ion analysis to determine the chemical makeup of the gases and determine their total concentration in the gas stream.
When the geothermal reservoir is being drilled, one method of analyzing oil and gas is called fluid-gas characterization. In this process, a sample of the reservoir is injected into a geothermal fluid chamber where the temperature and pressure of the fluid are measured. to determine the characteristics of the reservoir. The geothermal fluid chamber is also heated to 500 degrees Celsius in order to create a hot and cold environment, and to determine the density and boiling point of the reservoir gases.
