Curve Catalog Types
Contributing company names are prefixed with their RP66 company code to aid in generation of a single master list while differentiating common mnemonic and tool naming between companies.
| Catalog Type | Description |
|---|---|
| Company Codes | Energistics has long maintained the list of the data acquisition companies used by the DLIS exchange format (formerly API RP66). Each unique company has been assigned a number, which is used in a DLIS file. EXAMPLE: Baker Hughes Inteq = 15. This sheet contains an alphabetic listing of each company and its assigned code. The PWLS Curve Catalog re-uses these same numbers to avoid confusion caused by mergers and spinoffs of service and other data companies and allows for a combined export of all companies mnemonics in a single file. |
| Curves | A detailed list of curve/channel mnemonics, each mapped to a PWLS property, the appropriate Quantity Class (which determines the valid units of measure for the channel), the LIS mnemonic if one is defined (LIS mnemonics are limited to 4 uppercase characters), and a textual description of the curve; the list is grouped by company code. The column for PWLS Property on this spreadsheet maps to the PWLS Property List (the other spreadsheet). The values in the column Curve Unit Quantity Class derive from the Quantity Class in the Energistics Unit of Measure Standard. |
| Tools | A list of unique tools and various information about each. Grouped by company code with an alphabetic listing by Tool Code or Model. |
| Curves Within Tools | A list of tool codes mapped to a curve mnemonic, grouped by company. |
