Abstract
Processes are provided for conformance control in the production of hydrocarbons from reservoirs, involving the distribution of mobilizing injection fluids into a formation through a number of injection fluid distribution points spaced apart along an injection well. The volume and/or position of mobilizing fluid outflows at the distribution points is adjusted based on criteria that include selected reservoir parameters measured at spatially distributed measurement points in the reservoir. An operational system is provided so that these measurements provide a proxy for recovery chamber conformance.
