Estimating the term…
A sealant for an oil or geothermal well capable of setting within about 3 to about 6 hours at temperatures less than about 250° F. for shallow wells less than about 10,000 feet and deep wells greater than about 10,000 feet having MgO present in the range of from about 9.9 to about 14.5%, KH2PO4 present in the range of from about 29.7 to about 27.2%, class C fly ash present in the range of from about 19.8 to about 36.3%, class F fly ash present in the range of from about 19.8 to about 0%, boric acid or borax present in the range of from about 0.39 to about 1.45%, and water present in the range of from about 20.3 to about 21.86% by weight of the sealant. A method of sealing wells is disclosed as are compositions for very high temperature wells is disclosed as is a composition for treating oil field wastes.
A sealant for an oil or geothermal well capable of setting within about 3 to about 6 hours at temperatures less than about 250° F. for shallow wells less than about 10,000 feet and deep wells greater than about 10,000 feet, said sealant being comprised of:
A sealant for an oil or geothermal well capable of setting within about 3 to about 6 hours at temperatures greater than 250° F., comprising
A method of sealing a shallow or deep well at temperatures of less than about 250° F. with a compound that sets within about 3 to about 6 hours, comprising introducing into the well sufficient quantities of an aqueous slurry of:
A method of sealing a shallow or deep well at temperatures of less than about 250° F. with a compound that sets within about 3 to about 6 hours, comprising introducing into the well sufficient quantities of an aqueous slurry of:
A premixed powder for aqueous slurry of a sealant for an oil or gas well, said premixed powder comprising
A combination of oilfield waste and one or more of magnesium potassium phosphate binder (Ceramicrete), calcium phosphate binder using triple super phosphate (TSP), iron phosphate ceramics (Ferroceramicrete) and aluminum phosphate binder (Alucrete) in sufficient quantities to stabilize the waste.
