1. n. []

In matrix stimulation, a characteristic of rock that indicates formation permeability is not reduced when treating fluids and their additives contact the formation minerals or fluids inside the reservoir. Compatibility is especially important in sandstone treatments, in which potentially damaging reactions may occur. The treatment fluid should remove existing damage without creating additional damage, such as precipitates or emulsions, through interactions with the formation rock or fluids.
