Abstract: Multi-well fracture control incorporates physical well properties into a model for fracture geometry to determine optimal mitigation techniques for well interference effects. Sensors in a monitoring well and a treatment well measure well properties during fluid injection and pumping in the treatment well. The measurement data is used to constrain fracture geometry model. The fracture geometry model is then used to calculate fracture growth rates and direction which are used to calculate an estimated time for the occurrence of well interference effects in the multi-well system. From the fracture geometry model, fracture growth rates and direction, and the estimated time for the occurrence of well interference, locations of potential well interference effects are predicted. A mitigation strategy is planned based on the predicted location and time of well interference events. Treatment actions can be taken in anticipation of the well interference events.
