Abstract
A method for recovering hydrocarbons from an underground formation having a first exploited or partially exploited region and a second less exploited region in at least partial fluid communication with said first region. Electrical heating means is provided in the first region, and electrical energy supplied to the first region to raise or sustain its pressure to mitigate the loss of fluids and pressure from the second region due to hydraulic interaction with the first region. The electric heating affects the pressure by thermal expansion of the liquids and vapors present in or added to the first region and/or flashing of those liquids to vapors. The use of electric means is advantageous over the prior art by allowing for the redirection of injection fluids to more active regions of exploitation, and allows for more timely reclamation of the equipment and surface area above the first region.
