Methods for increased hydrocarbon recovery through mineralization sealing of hydraulically fractured rock followed by refracturing

摘要: The invention is a method of increasing hydrocarbon recovery through the biomineralization sealing fractured geological formations followed by refracturing, including preparing composition with biochemical components that delivered into subsurface cased well bore. Nutrient solutions are bore, thereby metabolizing nutrient to create mineralizing byproduct. Mineralizing subsurface, delivering composition, and targeted having existing formation fractures, casing openings. react byproduct produce minerals, which crystallize in strengthening fractures resulting sealed fractures. Targeted refractured new outside exposing areas trapped hydrocarbons production, increase recovery.
