HYDRAULIC FRACTURE PROXIMITY DETECTION USING STRAIN MEASUREMENTS

Described are systems and methods for determining a distance between a hydraulic fracture of a child well to a parent wellbore of a parent well. A distributed accoustic sensor fiber optic cable measures strain measurements along a length of the parent wellbore. A computing device then calculates the...

Zusammenfassung:	Described are systems and methods for determining a distance between a hydraulic fracture of a child well to a parent wellbore of a parent well. A distributed accoustic sensor fiber optic cable measures strain measurements along a length of the parent wellbore. A computing device then calculates the distance between the hydraulic fracture and the parent wellbore by inputting the strain measurements into a fracture strain model to solve for a location of the hydraulic fracture. A sub-surface process may be adjusted based on the calculated distance between the hydraulic fracture and the parent wellbore to avoid or utilize a frac hit.
