Contact of a crude feed with one or more catalysts produces a total product that includes a crude product. The crude feed has a total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids of at least 0.00001 grams per gram of crude feed. The crude product is a liquid mixture at 25° C. and 0.101 MPa. Contacting conditions are controlled such that the liquid hourly space velocity in a contacting zone is over 10 h−1 and the crude product has a total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids of at most 90% of the total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids 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.

1. A method of producing a crude product, comprising: contacting a crude feed with one or more catalysts in a fixed bed to produce a total product that includes the crude product, wherein the crude product is a liquid mixture at 25° C. and 0.101 MPa, the crude feed comprising one or more alkali metal salts of one or more organic acids, one or more alkaline-earth metal salts of one or more organic acids, or mixtures thereof, the crude feed having, per gram of crude feed, a total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids of at least 0.00001 grams, and at least one of the catalysts having, per gram of catalyst, at least 0.001 grams of: one or more metals from Column 6 of the Periodic Table, one or more compounds of one or more metals from Column 6 of the Periodic Table, calculated as weight of metal, or mixtures thereof; andcontrolling contacting conditions such that a liquid hourly space velocity of crude feed per total volume of catalyst in a contacting zone is over 10 h−1, and the crude product has a total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids of at most 90% of the content of alkali metal, and alkaline-earth metal, in metal salts of organic acids in the crude feed, wherein content of alkali metal, and alkaline-earth metal, in metal salts of organic acids is as determined by ASTM Method D1318. 2. The method of claim 1, wherein the liquid hourly space velocity is at least 15 h−1. 3. The method of claim 1, wherein contacting comprises contacting the crude feed in the presence of a hydrogen source and/or an inert gas. 4. The method of claim 1, wherein contacting comprises contacting the crude feed in the presence of a hydrogen source, and during contacting the crude feed uptakes molecular hydrogen at a selected rate to inhibit phase separation of the crude feed during contacting. 5. The method of claim 1, wherein at least one of the catalysts has a pore size distribution with a median pore diameter of at least 180 Å. 6. The method of claim 1, wherein the crude feed and crude product both have a C5 asphaltenes content and a MCR content, and a sum of a crude feed C5 asphaltenes content and a crude feed MCR content is S, a sum of a crude product C5 asphaltenes content and a crude product MCR content is S′, and the contacting conditions are also controlled such that S′ is at most 90% of S, wherein C5 asphaltenes content is as determined by ASTM Method D2007 and MCR content is as determined by ASTM Method D4530. 7. The method of claim 1, wherein the crude feed and crude product both have a C5 asphaltenes content and a MCR content, and the contacting conditions are also controlled such that a weight ratio of a MCR content of the crude product to a C5 asphaltenes content of the crude product is in a range from about 1.2 to about 2.0, wherein C5 asphaltenes content is as determined by ASTM Method D2007 and MCR content is as determined by ASTM Method D4530. 8. The method of claim 1, wherein the total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids in the crude product is at most 50% of the content of alkali metal, and alkaline-earth metal, in metal salts of organic acids in the crude feed. 9. The method of claim 1, wherein the total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids in the crude product is in a range from about 1% to about 80% of the content of alkali metal, and alkaline-earth metal, in metal salts of organic acids in the crude feed. 10. The method of claim 1, wherein the crude product has from about 0.0000001 grams to about 0.00005 grams of alkali metal, and alkaline-earth metal, in metal salts of organic acids per gram of crude product. 11. The method of claim 1, wherein at least one of the catalysts has a pore size distribution such that at least 60% of the total number of pores in the pore size distribution have a pore diameter within about 45 Å of a median pore diameter of the pore size distribution. 12. The method of claim 1, wherein the Column 6 metal catalyst comprises in addition one or more elements from Column 15 of the Periodic Table, one or more compounds of one or more elements from Column 15 of the Periodic Table, or mixtures thereof. 13. The method of claim 1, wherein the Column 6 metal catalyst comprises in addition one or more metals from Columns 7-10 of the Periodic Table, one or more compounds of one or more metals from Columns 7-10 of the Periodic Table, or mixtures thereof. 14. The method of claim 1, wherein the Column 6 metal catalyst comprises in addition one or more metals from Columns 7-10 of the Periodic Table, one or more compounds of one or more metals from Columns 7-10 of the Periodic Table, or mixtures thereof; and one or more elements from Column 15 of the Periodic Table, one or more compounds of one or more elements from Column 15 of the Periodic Table, or mixtures thereof. 15. The method of claim 1, wherein at least one of the Column 6 metals is molybdenum. 16. The method of claim 1, wherein at least one of the Column 6 metals is tungsten. 17. The method of claim 1, wherein the Column 6 metal catalyst comprises in addition nickel, one or more compounds of nickel, cobalt, one or more compounds of cobalt, or mixtures thereof. 18. The method of claim 1, wherein the crude feed is contacted in a contacting zone that is on or coupled to an offshore facility. 19. The method of claim 1, wherein contacting comprises contacting the crude feed in the presence of a hydrogen source. 20. The method of claim 1, wherein the method further comprises combining the crude product with a crude that is the same as or different from the crude feed to form a blend suitable for transportation and/or treatment facilities. 21. The method of claim 1, wherein the method further comprises processing the crude product to produce transportation fuel. 22. The method of claim 1, further comprising processing the crude product to produce a transportation fuel. 23. The method of claim 22, wherein the processing comprises distilling the crude product into one or more distillate fractions. 24. The method of claim 22, wherein the processing comprises hydrotreating. 25. The method of claim 22, wherein the liquid hourly space velocity of crude feed per total volume of catalyst is at least 11 h−1. 26. The method of claim 1, wherein the liquid hourly space velocity of crude feed per total volume of catalyst is at most 30 h−1.
