Remtech Enzyme Formulation Restores Oil Well Production
Preliminary field results from several Texas oil field injection tests conducted recently have yielded up to a 34% increase in oil production within three to five days after Well Restore (HCZyme/AGZyme) applications, where paraffin build-up (clogging oil wells) has been a historic problem.
HOW WELL RESTORE WORKS:
Saturated unbranched acyclic hydrocarbons tend to plate out on well walls (solidification points at 95 -104 oF). During the deposition process, other material such as sand, scale and oil become entrained in the scale. Imbedded deposits contain native hydrocarbon-acclimated bacteria and fungi that the enzyme treatment stimulates. The enzyme formulation acts as a natural surfactant, penetrating and loosening deposits from the pipe walls and the nearby formation, while at the same time assimilating mineral deposits (i. e., calcium, magnesium, etc.), which neutralize and condition paraffin deposit making them less sensitive to salinity and divalent ion concentrations. HCZyme accelerates bacterial reactions with the straight-chained bonds of the paraffin, breaking it down into simple shorter-chained alkanes lowering viscosities and increasing influx rates. The simplest of these reactions for methane digestion is - (CH4 + 2O2 => CO2 + 2H2O).
Within three to five days, the rigid structure of the solidified paraffin deposit is destroyed as the combination of reactions and conditioning effects allow the well to "breathe." Reaction residues can be easily flushed from the well in liquid or gaseous form, as the well is placed back into production. Since the "soak cycle" is limited in duration, adverse bacterial blooms and associated slime problems in the well bore are avoided.
A BETTER SOLUTION:
Oil and gas production can be significantly hindered by various types of well bore and near-well bore formation damage that either plug up perforations or reduce the effective permeability of the oil-bearing formation. Existing well stimulation methods used to remedy these problems can often have high chemical, pumping and disposal costs, and can produce additional damage if not conducted properly. The most commonly applied method to treat production problems caused by these organic deposits is 'hot-oiling'. This method, however, often poses a more serious problem of reintroducing these undesirable organic deposits back into the formation and has limited effectiveness in preventing/inhibiting buildup of additional deposits.
Crude oil contains paraffins (waxy hydrocarbon mixtures) that will thicken and solidify the crude at a certain temperature, called the "cloud" point. Oil field operators usually halt pumping intermittently to clean out paraffin-clogged lines with a device that flushes heated oil downhole to melt the paraffin. If the well is not regularly treated with hot oil, sucker rods may stick and/or break. Both scenarios are expensive and result in decreased oil production.
HCZyme/AGZyme well treatment removes particulates and organic and inorganic precipitates from well bores and the surrounding formation, thereby restoring permeability and improving the economics of producing and older wells that might otherwise be abandoned.
HCZyme and AGZyme are proprietary non-pathogenic enzyme formulations. HCZyme is a specialized enzyme agent derived from the family of bacteria and fungi known to degrade petroleum constituents. AGZyme is a similar specialized enzyme agent, designed to condition minerals and metals in many environments for organic assimilation.
