VARCHAR2(64) |
| Curve_Business_Value | STRING64 | NA |
PWLS defined, industry standard reference value indicating the relative importance of (generic) curves for general purpose usage. Reference values are High, Medium, and Low. High Value Curves are needed for most everyday purposes, i.e., curves loaded to long-term storage for future use by petrophysicists. Medium Value Curves are those needed occasionally. Low Value Curves are those not normally used by oil companies, e.g., diagnostic curves, basic physical measurements (voltages), even if they are routinely used by service companies, e.g., for calibration. [Low Value Curves are not assigned industry standard curve names. Implicitly, these are considered to be classified as Auxiliary Curves. These curves are usually stored in original format files, e.g. DLIS, LIS.] (PWLS 1.0). | No |
