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. Contacting conditions are controlled such that the crude feed, during contact, uptakes hydrogen at a selected rate to inhibit phase separation of the crude feed during contact. One or more properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

What is claimed is: 1. A method of producing a crude product, comprising: contacting a crude feed with one or more catalysts in the presence of a hydrogen source 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, wherein at least one catalyst includes a Column 6 metal in combination with a support and has a pore size distribution having a median pore diameter of at least 120 Å; and controlling contacting conditions such that the crude feed, during contact, uptakes hydrogen at a rate in a range from about 1-20 Nm3 hydrogen/m3 crude feed; and such that the crude product has an API gravity of about 80% to about 120% of an API gravity of the crude feed, wherein API gravity is as determined by ASTM Method D6822 wherein the P-value of the crude feed is initially at least 1.5 and such P-value increases or is relatively stable during contacting. 2. 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. 3. 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. 4. The method of claim 1, wherein the contacting conditions are also controlled such that the crude product has a total acid number (TAN) of less than 0.3. 5. The method of claim 1, wherein contacting the crude feed also comprises contacting the crude feed with at least one of the catalysts at a first temperature followed by contacting at a second temperature, and the contacting conditions are also controlled such that the first contacting temperature is at least 30° C. lower than the second contacting temperature. 6. 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. 7. The method of claim 1, wherein at least one of the catalysts comprises one or more metals from Columns 5-10 of the Periodic Table, one or more compounds of one or more metals from Columns 5-10 of the Periodic Table, or mixtures thereof 8.
