Abstract
Methods of controlling flow into a formation through the use of a stimulation valve in a tubular assembly installed in a well. Fluid is pumped into the formation through one or more ports in the stimulation valve. The stimulation valve defines a conduit for flow of fluids through the stimulation valve. The ports are adapted to allow flow of fluids between the conduit and the exterior of the stimulation valve and to receive a ball sealer for shutting off flow of fluids through the ports. The ports then are closed by introducing a plurality of ball sealers into the fluid. The fluid carries the ball sealers into the valve where they seat on and shut off flow of the fluid through the ports.
