  • Patent number: 6455483
    Abstract: A well stimulation and purging composition which is typically used in well cleanup, well stimulation and formation purging applications for enhancing oil and gas production. The composition is a cationic surfactant characterized by a homogenous aqueous solution of a coco diamine amido benzyl chloride type quaternary compound, phosphate chelator/ester, isopropanol anhydrous, ammonium bisulfide, and potassium chloride or a clay stabilizer formulation, and aids in extracting water and condensate from wells and dissipates, disperses and retards bacterial growth and buildup of iron sulfide, iron oxide, calcium and salt. The composition is applied to the wells in order to clear the water and condensate and significantly enhance total well production by chelating minerals such as salt, iron and calcium; retarding bacterial growth; and flocculating and foaming the water, condensate and solids from the well.

  • Patent number: 6262002
    Abstract: A liquid composition and method for chemical remediation of eroded soil or oil-damaged vegetation and/or soil. In a preferred embodiment the soil remediation composition is characterized by a homogenous aqueous solution having selected quantities of urea, dimethylsulfoxide (DMSO), hydrated calcium nitrate and an ionic or non-ionic surfactant such as ether sulfate. The composition solution is typically sprayed either full-strength or at a selected dilution on the oil-damaged soil and vegetation or eroded, sparsely-vegetated or oil-damaged soil, and rapidly penetrates the soil to the vegetation roots to cleanse the vegetation and soil, activate hydrocarbon-consuming bacteria in the case of oil spills, and promote plant nitrogen assimilation and rapid growth and ground coverage of vegetation. The treated soil is typically seeded to enhance grass or vegetation growth and coverage.

  • Patent number: 6143709
    Abstract: Well stimulation and purging compositions for enhancing oil and gas production. The compositions include two base solutions which are typically used in combination with each other in well cleanup, well stimulation and formation purging applications. The first base solution is an anionic surfactant characterized by an aqueous solution of ether sulfate, isopropanol anhydrous, ammonium bisulfide, and either potassium chloride or a clay stabilizer formulation. In treatment of oil and gas wells, the solution is capable of reducing surface tension of well fluids and dissipating and dispersing various solids and minerals by dehydrating the well bore and well formation. The composition flocculates and foams the solids, minerals, water and condensate to the well surface.
