Abstract: Methods and systems for contacting a crude feed that has a total acid number (TAN) of at least 0.3 with one or more catalysts produces a total product that includes a crude product are described. The one or more catalysts may include a first catalyst and a second catalyst. The crude product is a liquid mixture at 25° C. and 0.101 MPa and the crude product has a TAN of at most 90% of the TAN of the crude feed. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

Abstract: Contact of a crude feed with one or more catalysts produces a total product that include a crude product. The crude feed may a total acid number of at least 0.3. The crude product is a liquid mixture at 25° C. and 0.101 MPa. The crude product may have a total acid number of at most 90% of the total acid number of the crude feed. At least one of the catalysts may include one or more Column 6 metals of the Periodic Table and one or more Column 10 metals of the Periodic Table. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

Abstract: Contact of a crude feed with one or more catalysts produces a total product that includes a crude product. The crude feed has a residue content of at least 0.2 grams of residue per gram of crude feed. At least a portion of the crude product may be produced as a vapor. The crude product is a liquid mixture at 25° C. and 0.101 MPa. One or more properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

Abstract: Contact of a crude feed with a hydrogen source in the presence of an inorganic salt catalyst produces a total product that includes a crude product. The crude feed has a residue content of at least 0.2 grams of residue per gram of crude feed. The crude product is a liquid mixture at 25° C. and 0.101 MPa. One or more properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed. In some embodiments, the crude product may have an increased content of one or more compounds relative to the content of the same one or more compounds in the crude feed.

Abstract: Contact of a crude feed with one or more catalysts produces a total product that includes a crude product. The crude product is a liquid mixture at 25° C. and 0.101 MPa. The one or more catalysts may include a catalyst that has a median pore diameter of at least 90 ?. One or more properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

Abstract: An in situ process for treating a hydrocarbon containing formation is provided. The process may include providing heat from one or more heat sources to at least a portion of the formation. Heat sources may include a natural distributed combustor. The natural distributed combustor may include an oxidizing fluid source to provide oxidizing fluids to a reaction zone in the formation to generate heat within the reaction zone. The heat may be allowed, in some embodiments, to transfer from the reaction zone to a selected section of the formation such that heat from one or more heat sources pyrolyzes at least some hydrocarbons within the selected section. Hydrocarbons may be produced from the formation.
