[0128] Preparation of Microbial-Based Products

[0129] A microorganism-based product of the invention is simply a fermentation broth containing the microorganisms and / or microbial metabolites and / or any residual nutrients produced by the microorganisms. Fermentation products can be used directly without extraction or purification. Extraction and purification can be readily achieved, if desired, using standard extraction and / or purification methods or techniques described in the literature.

[0130] Microorganisms in microorganism-based products can be in active or inactive form. Microbial based products can be used without further stabilization, preservation and storage. Advantageously, direct use of these microbial-based products maintains high viability of the microorganisms, reduces the possibility of foreign material and unwanted microbial contamination, and preserves the viability of the by-products of microbial growth.

Embodiment 1

[0245] Example 1 - Liquefaction of Precipitated Asphaltenes Using STAR 3+

[0246] The Star 3+ process of the present invention is used to liquefy refinery fully precipitated and hardened asphaltenes. As shown in Figures 1-6, solutions of Star 3+ (500ml), 4g / L purified SLP and ionic liquid were compared for their ability to liquefy 100g of asphaltene precipitate in a shake flask. like Figure 7 The effectiveness of the Star 3 treatment was also compared to that of the Star 3+ as shown.

[0247] As shown in Figure 8, the flask was subjected to shaking for 5 hours, and then the amount of asphaltene precipitated was measured.

Embodiment 2

[0248] Example 2 - Example protocol for fermenting bioemulsifying yeast

[0249] A nutrient medium comprising two carbon sources is used to grow yeast of eg the Wickhamia, Pichia and / or Starmerella clades. The first carbon source is a sugar such as dextrose or glucose at a concentration of 20 to 50 g / L. The second carbon source is a hydrophobic carbon source such as purified canola oil or vegetable oil at a concentration of 50 to 100 g / L.

[0250] Nitrogen sources such as urea or ammonium salts are also added, as well as sources of magnesium, phosphate and potassium.

[0251] Fermentation occurs for 1 to 5 days. Final concentrations of yeast that can be obtained range from about 500 million to 2.5 billion CFU / mL.

[0252] Example 3 - Fermentation of Candida globosa for Sophoryl ester (SLP) production in a 110 L reactor

[0253] A portable, airlift fully enclosed reactor operated by a PLC with water filtration, temperature control unit and on-board blower was used. When gr...

Abstract

The subject invention provides microbe-based products, as well as their use in simultaneously enhancing oil recovery from an oil well while efficiently removing contaminating compositions such as biofilm, scale, paraffin, and / or asphaltenes from oil production equipment and oil-bearing formations. The subject invention can also be used to disperse paraffin and asphaltene precipitates, and to reduce the viscosity of heavy crude oil. The subject invention further provides materials and methods for bioremediation of hydrocarbon-contaminated sites.

Background technique [0003] Petroleum exists in small pores and narrow fractures in the body of reservoir rock below the Earth's surface. The natural pressure of the reservoir causes the oil to flow to the surface, providing initial production; however, as oil production progresses, the reservoir pressure is depleted to the point where artificial lifting or pumping is required to maintain an economical rate of oil production.
