| Name | Rock_Sample_Preparation |
|---|---|
| Entity Type | Table |
| Description | An activity during which a preparation method is utilized to prepare a rock sample for analysis, such as extracting internal fluids, cleaning, drying, injecting a fluid into the pore space, coating in metal or carbon, staining for minerals, etc. Many preparation methods can be utilized for a single rock sample. Additionally, it is possible for the same preparation method to be utilized more than once for a rock sample. |

An activity whose Existence_Kind is "Required" could have State values like "under investigation", "proposed" and "AFE approved". Note: The valid list of activity states will vary from one kind of activity to another, so the values entered into this column are not validated via a lookup table. | No |
