Abstract
Treatment fluid may be injected into a wellbore of a geological formation to stimulate fracturing of the geological formation. A plurality of measurements may be received from one or more sensors on a surface of the geological formation or downhole which measures an indication of change of the geological formation based on the stimulation. A fracture configuration of a fracture in the geological formation may be determined based on an Kalman gain and the plurality of measurement data. Injection of the treatment fluid into the wellbore may be adjusted based on the fracture configuration.
