Abstract
A well 1 is drilled or exists that passes through the earth's surface 2 and underlying rocks 3 to connect with a subterranean hydrocarbon reservoir 4 that contains hydrocarbons 5 and commonly brine 6 (which can include formation, interstitial, connate and injected water). Well 1, (there may be a plurality of well 1's) allows the contents of reservoir 4, either hydrocarbons 5 or brine 6, to flow to the surface.

1-20. (canceled)
A process for recovering energy from a subterranean hydrocarbon reservoir comprising hydrocarbons, said reservoir being in fluid communication with energy conversion means via a first conduit, wherein the process comprises:
- delivering an oxidant to the reservoir thereby elevating the ambient pressure and/or temperature within the reservoir resulting in displacement of at least a portion of the contents of the reservoir to deliver at least a portion of the contents at elevated pressure and/or temperature to the energy conversion means via the first conduit.
A system for recovering energy from a subterranean hydrocarbon reservoir comprising hydrocarbons, said reservoir being in fluid communication with energy conversion means via a first conduit, wherein the system further comprises means for delivering an oxidant to the reservoir thereby elevating the ambient pressure and/or temperature within the reservoir resulting in displacement of at least a portion of the contents of the reservoir to deliver at least a portion of the contents at elevated pressure and/or temperature to the energy conversion means via the first conduit.
