-At the present time, more than 9,000 offshore platforms are in service worldwide, operating in water depths ranging from 10 ft to greater than 5,000 ft. Topside payloads range from 5 to 50,000 tons, producing oil, gas, or both. A vast array of production systems is available today (see Fig. 1). The concepts range from fixed platforms to subsea compliant and floating systems.
+Wax components can precipitate from petroleum fluids when the original equilibrium conditions of the reservoir are changed so that the solubility of the waxes is reduced; however, wax precipitation does not necessarily lead to deposition. This page discusses wax precipitation behavior and experimental measurements to predict the tendency of a crude oil to precipitate wax.

-Microbial Exploration Technology (MET), also called microbial enhanced oil recovery (MEOR), is a method of enhanced oil recovery (EOR) that identifies microorganism levels in soil near reservoir surfaces to estimate hydrocarbon levels. This method is largely based on the premise that the more microorganisms present, the more hydrocarbons are present for those microorganisms to feed on.
+Biodegradation occurs when bacteria, fungi, or other organism or biological process chemically dissolves materials. The process can be beneficial or detrimental within the industry depending on the circumstances. For instance, biodegradation via bacteria can aid in the cleanup of oil spills.
+During biodegradation, microbial organisms metabolize petroleum, degrading the hydrocarbon content. The process can take more or less time depending on the amount of type and amount of bacteria, the reservoir or ecosystem in which the bacteria are found, and the amount of oxygen present.
