The Pay Report generates a listing from digital log curve data over one or more selected user zone intervals. The report shows a foot-by-foot listing of the curve values as report columns. The user may define a "summary type" for each column, such as, average value, total, cumulative, etc.
To open the Pay Report tool, selectCompute>From Logs>Pay Reportfrom the menu bar at the top of the Main Module
Zones tab
Select Zones To Report Pay - Choose one or more zone intervals for which you want the pay report.
Report Wells - The report can list all selected wells or just for the current well.
Depth Increment for Report - This option controls the sample rate for the foot-by-foot listing. You can either use the sample rate for the log curves or specify a different sample rate. For example, if you have curves sampled at 0.25 feet, you might create a report and list only every 1 foot. The sample rate is given in feet/sample (or meter/sample).
Log Curves tab
Report Column Definitions - This section displays the report columns. Each column is associated with a log curve and shows the curve name, the column title for the report, the column width in characters, the number of digits to the right of the decimal point, and summary type.
Use Aliases - This option allows Petra to use log curve aliases.
Sum Type
Summary type can be changed by clicking the left mouse button on the "sum type" cell for a specific column. Available types are:
None - Column will have no summary values.
Total - The column summary will show the total sum of the curve values.
Total (weighted by rate) - The total sum will be multiplied by the sample rate. For example, if the curve in the column was a "pay flag" and the sample rate was 0.5, the total "pay" would be the 1/2 of the total count which would reflect the actual number of feet of pay.
Average - The average curve value is displayed.
Average (non-zeros only) - Zero-valued curve samples are excluded from the average calculation.
Cumulative - The running total is displayed for each sample.
Minimum - The minimum curve value is listed at the bottom of the column.
Maximum - The maximum curve value is listed at the bottom of the column.
Discriminator Curve
This option uses a discriminator curve to filter the statistical data. At depths where the discriminator curve contains a 0 or null value, the corresponding depth will be skipped in the pay report. If this box is checked and the discriminator log is absent, the pay report will not be calculated.
Available Curves List
To Add a Curve as a Report Column - Select the curve in the "available curves" drop-down list. Chick the "Add Curve" button. Set the "sum-type".
To Replace a Curve - Select the curve in the "available curves" drop-down list. Click in the curve title cell for the column to replace. Then click the "Replace Curve" button.
To Drop a Curve Column - Click in the curve title cell for the column to replace. Then click the "Drop Curve" button.
File tab
Load Template - This button loads an external Pay Report temPlate (*.PRP) file.
Save Template - This button saves the current color scheme to an external Pay Report temPlate (*.PRP) file
