A control model of water injection from a growing hydrofracture into a layered soft rock is developed. An optimal injection controller is designed to manage the rate of water injection in accordance with hydrofracture growth and formation properties. Three different modes of controller operation are presented, which include the continuous mode, piecewise constant mode, and the exact optimal mode. It is shown that the early water injection policy and the resulting hydrofracture growth is expected to affect the performance of the waterflood.
