PO.DCA.Diag.Bourdet Function
Description:
Calculates the Bourdet (smoothed) derivative at point t. Used for flow regime identification and production diagnostics.
Excel Function Syntax:
=PO.DCA.Diag.Bourdet(x_values, y_values, t, L)
Parameters:
| Parameter | Description |
|---|---|
| x_values | Sample points (time or log-time), sorted ascending. |
| y_values | Sample values (rate, pressure, or cumulative production). |
| t | Point at which to calculate derivative. |
| L | Smoothing parameter. Minimum distance for neighboring points. L=0 uses adjacent points (no smoothing). Typical: 0.1-0.5 for log-time data. |
