Analytical techniques have been applied to the study of crude oil in many laboratories across the world, as well as in oil exploration operations. The kind of analysis that is used by these laboratories involves tests of physical, chemical and physical properties. What is important about these laboratory tests is that they are an indication of how potential deposits might behave under various environmental conditions.
Physical and chemical analysis has been one of the most widely used analytical techniques. Analytical chemists use this technique to help them determine the exact chemical make-up of a sample, or to predict what condition the sample might be in if it were exposed to a change in the environment. If there is a change in the composition of the sample, the analytical chemist will need to know why.
Chemical analysis can be very informative about the state of a deposit. A new solution can take on different and unusual qualities in comparison to a pre-existing solution. In some cases, the composition of a geological deposit might change due to reaction with water, or due to constant pressure from underground.
Metals such as gold and copper can occur in abundance in nonmetallic substances such as water. A new metal concentration can be determined by the amount of gold or copper present in a sediment sample. These types of analysis may be more difficult than the previous forms of analytical testing.
The most basic physical methods use gravity, electromagnetism and microscopy. Gas chromatography is also used, but has a longer time required period than others. There are also methods such as infrared spectroscopy, ultraviolet spectroscopy and microprobe analysis that are used to analyze the composition of oil.
The value of a gold assay for oil is not entirely based on the initial composition of the oil products, but also on its stability under the different weather conditions in which the products are produced. To avoid oversimplification, gold can be found in different forms, including pure gold, as fine dust and as flecks of dust in air samples. If a product is found to contain gold, then the gold content is reported on the report. The high quality gold in oil, which is usually very malleable, is a result of processes involving alkali metals.
If a sample of oil is found to contain high quantities of gold, then it is considered to be a good industrial grade. If the products are heavily refined and cleaned, then the oil should be reported as being generally purer than an undeclared sample. The higher the concentration of gold in the product, the better the refining process will affect the product.
Because gold is expensive and not easily obtained, the process used to produce it is also important. Gold mining has been conducted in many parts of the world and the mines are run by large companies and private individuals. There are many different forms of gold mining that the gold deposits can take, but the primary extraction process produces the most pure and desirable grade of gold.
There are a number of different ways to extract gold from the ground. One method involves using a process called leaching. This method uses an acidic solution to dissolve large amounts of the mineral into the liquids that have already been extracted.
Another way to Leach the gold out of the rocks is through steam. The gold is dissolved into a process called activated steam distillation. Large amounts of the minerals are removed by heating the solution to about 2,000 degrees Fahrenheit.
A third method uses vapor to dissolve the gold into the water vapor which is already present in the atmosphere. This process takes a few days to complete, and a large amount of water is used to dissolve the gold particles.
Whether an analytical report is used for oil, gas, minerals or metals, there is a mathematical equation that calculates how much of a material can be removed from the original sample. There are a number of steps in this process and many variables that will affect the final value of the analytical report. these are the parameters that make the average grade for analyzing oil and its components.
