Patent 11156063 was granted and assigned to Advantek Waste Management Services Llc on October, 2021 by the United States Patent and Trademark Office.
Methods and apparatus are provided for optimizing operations for a fracturing injection waste disposal well especially where the formation is damaged or tight such that pressure fall-off tests are impractical due to extended leak-off rate times. Formation closure pressure and formation stress are calculated using Instantaneous Shut-in Pressure rather than traditional methods requiring actual fracture closure.
