Process for the downhole upgrading of extra heavy crude oil

A down hole hydroconversion process improves the viscosity, API gravity, and distillate proportions of heavy crude oils by employing a hydrogen donor, methane and steam down hole wherein the mineral formation down hole acts as a catalyst for the hydroconversion process.
