Colloidal

SCIENCE – Proprietary Colloidal Chemistry Process at the "NANO" scale

"Unlike other green cleaners, these actually work in oilfield applications"

Food grade ingredients, such as soy, corn, grain, potatoes and other forestry materials (plants & trees) are processed to form a particle called a micelle. Comprised of a collection of linear molecules of fatty esters and fatty acids clumped together in the shape of a sphere, the micelle's small particle size (one to four nanometers), combined with its extremely high surface area to volume ratio enable it to penetrate complex carbon molecules and emulsify organic matter. These linear molecules or micelle have a hydrophobic tail and a hydrophilic head and are activated when mixed with sufficient amounts of water so that each micelle is then completely surrounded by a thin layer of water molecules. The outer hydrophilic shell aggressively searches for and bonds with water molecules, making them hyper-mobile.

The colloidal micelles then works to break down long chain hydrocarbon bonds in fats, oils and grease (FOG) and hold them in suspension when mixed with water. Individual micelles repel each other like opposing magnets while attracting solid particles and breaking down hydrocarbon bonds into smaller molecules and/or atoms.

Once solid particles have attached themselves to the colloidal micelle, the micelle holds them in suspension, preventing re-soiling from occurring and safely allowing FOG to be permanently dissolved in water. The wash off is completely biodegraded and becomes soil constituents such as nitrate, dissolved oxygen, carbon dioxide, biomass and water. Mixed together in a much diluted water solution, colloids drastically reduce surface tension and work as a dispersing agent that carries other active ingredients more effectively than common surfactants.

Cleaning & Bio-remediation

After a spill, during stimulation or when cleaning, hydrocarbons are subjected to physiochemical processes such as evaporation or photochemical oxidation which produce changes in oil composition. But the most important process acting on the oil is biodegradation. It is well established that most crude oils are biodegradable to an extent, especially components as short linear alkanes or simple aromatic hydrocarbons. However, the heavy fraction (made of long-chain saturated and poly-aromatic hydrocarbons and a considerable fraction of asphaltenes and resins) is generally recalcitrant to degradation. Crude oil and subsequent refined oils find their way into the marine ecosystem where the natural populations of oxidizing micro biota are generally overcome and succumb to the spilled oil.

G-CLEAN oilfield application products are formulated to enhance the response of the natural bacterial population after the spill and to exponentially speed up oil degradation taking place at the contaminated sites. Due to its biological origin, crude oil is easily solubilized

G-CLEAN oilfield application products creating a non-reversible nano emulsion. The oils biodegradation products are CO2, nitrogen and micro carbon, which because of their extremely small size (1-4 nanometers) are the perfect food source for algae, plankton and small vertebrates.


Surfactants

Surfactants have two ends, one attracted to oil and the other attracted to water:

  1. Water-Compatible (hydrophilic)
  2. Oil-Compatible (Lipo or Oleo-philic)

The solvent enables the surfactants (active ingredients) to be applied and helps get them through the oil film to the water interface (water, hydrocarbon and glycols). At the interface, the surfactants reduce the surface tension allowing the oil to enter the water as tiny droplets which are degraded by natural bacteria.



BIODEGRADABLE OIL WELL REMEDIATION FLUID AND METHOD OF USE:

The invention relates to a formulation for a natural product as a replacement for the use of traditional acidic chemical formulations for the emulsification, removal and release of paraffin and asphaltenes from low producing or pumped off wells and reservoirs with the use of traditional methodologies. Also a method of use of formulation for stimulating an oil well consisting of introducing into the wellbore a biodegradable, colloidal cleaning fluid system containing a micellar solution of fatty acids, such as coconut oil fatty acids, a polysorbate emulsifier, a non-ionic surface active agent, and a non-ionic detergent such as D-Glycopyranoside hexyl. The fluid system may be further in the form of a nano-emulsion that is formed by combining a micellar solution with one or more emulsifiers, an alcohol, and water. The fluid system may be used in well remediation and stimulation as well as additional, alternative applications such as the cleaning of surface and/or down hole equipment.


BIODEGRADABLE CLEANING CONCENTRATE NANOEMULSION AND METHOD OF USE:

The invention relates to a formulation for a biodegradable cleaning concentrate nano-emulsion and method of use as surface cleaning agents. The cleaning concentrate nano-emulsion comprises a solution of fatty acids, such as tall oil fatty acids, a saponifier, such as monoethylamine (MEA) and a water soluble solvent such as tetrahudrofufuryl alcohol (THF-A), wherein the solution has a mean droplet size of less than 100nm. The composition may also include at least one non-ionic surface active agent. The concentrate composition may be used for heavy duty surface cleaning applications as well as additional, alternative applications such as the cleaning of water and oil spills.


BIODEGRADABLE HYDRAULIC FRACTURING FLUID NANOEMULSION AND METHOD OF USE:

It has been discovered that biodegradable and non-toxic nano-emulsions can perform multiple beneficial functions in an aqueous fracturing fluid. Some of the multiple functions include various combinations of the following: defoamer, viscosity reducer, gel fragment emulsifier and the like. Some of the nano-emulsions used in the composition include colloidal compositions including, but are not necessarily limited to, micellar solutions of fatty acids, such as tall and coconut oil fatty acids, a polysorbate emulsifier, a non-ionic surface active agent and a non-ionic detergent and mixtures thereof.
