VCF Factor Tables
These tables, named SF_VCF Section 1 and SF_VCF Section 3, contain information used to calculate the volume correction factor adjustment based on the material characteristics.
SF_VCF Section 1
The table has the following column format.
SF_VCF Section 1 Column Format
| Column | Description |
|---|---|
| Material | Identifies the common name of the material. |
| Vcftype | Is the value from the Material Table used in conjunction with the Temp Min and max, API Min and Max to select the K0 and K1 factors for the VCF calculation. |
| TempMin | Specifies minimum temperature (F). |
| TempMax | Specifies maximum temperature (F). |
| APIMin | Specifies minimum API density. |
| APIMax | Specifies maximum API density. |
| ko and k1 | Coefficients used to calculate the expansion coefficient. The API-temperature range specifies the validity for ko and k1. |
The API-temperature ranges specify the validity of the ko and k1 coefficients used to calculate the expansion coefficient. The expansion coefficient is used in the calculation of the VCF. The table below shows a partial list of the VCF Section 1 Table. VCF section table 1 is the implementation of API TABLES 6A, B, and C using the methods published in API volume 10.
Note: This table is populated by default with the materials as shown in the figure above. These names and descriptions can be changed or deleted.
SF_VCF Section 3
This table contains information used to calculate the volume correction factor based on the material characteristics. The table has the following column format.
SF_VCF Section 3 Column Format
| Column | Description |
|---|---|
| Material | String that identifies the common name of the material. |
| Vcftype | Is the value from the Material Table used in conjunction with the Temp Min and max, API Min and Max to select the K0 and K1 factors for the VCF calculation. Is the value from the Material Table used to select the A and B values for the VCF calculation. |
| B column | Lists the coefficients used to calculate the expansion coefficient of the fluid. |
This table is populated by default with the materials as shown in the figure above. These names and descriptions can be changed or deleted.
The VCF calculation needs VCF Section 1 and Section 3 tables. If these table do not exist the following message appears:
