A method for improving the thermal characteristics of cement compositions is provided in which fine resilient graphitic carbon particles ('RGC') are substituted for a portion of the fine aggregate (typically sand) in the cement formulation. For the purposes of the present disclosure, 'fine' is intended to describe particulates having a mesh size of less than about 8 mesh, or a particle size of less than about 2.38 mm, or, more preferably when referring to RGC, a mesh size of less than about 16 mesh and a particle size of less than about 1.19 mm. &#x201c;Resilient&#x201d; is intended to describe graphitic carbon particles that exhibit a rebound of at least about 20% after compression to 10,000 psi.

Hydrocarbon containing formations can be processed using an in-situ liquefaction technique. This new technique embodies systematic temperature elevation applied to subsurface formation allowing recoverable hydrocarbons to reach a Newtonian fluid viscosity suitable for extraction.
