Create Vint logs from checkshots creates an interval-velocity LAS log for each eligible well in one run. Unlike the Vint curve calculated only for display from a checkshot, the resulting log can be selected in Cross-plot and Log calculator.

Create the logs

In the Data Manager, right-click Wells to process all wells, or right-click a well folder or filter to process its wells. You can also select several wells and right-click the selection. Choose Create Vint logs from checkshots.

The dialog shows the number of wells in the selected scope. For Sampling, keep Regular step to create regularly sampled logs, or choose Anchors only to retain the checkshot anchor sampling.

With Regular step, set Step to Main log step of each well (the default), or choose Same step for all wells and enter a positive Step for all wells. Set Depth range to Checkshot top to bottom (the default) or Whole well.

Enter a non-empty Output curve name, or keep the default Vint, then confirm to start. A progress window tracks the run and lets you stop it.

Result and existing curves

A well needs a checkshot with at least two anchors. The generated interval-velocity values follow the checkshot model at measured depths along the well trajectory, including deviated wells, and use the project's velocity units. The curve is stored as a LAS log with the project and is available as an ordinary log after reopening a saved project. Wells without a usable checkshot are skipped.

Running the command again updates its previously generated log in each well instead of adding a duplicate. If another LAS file in a well already contains the chosen curve name, a prompt asks whether to replace that curve. Yes or No applies to that well; Yes to All or No to All applies to the remaining conflicts; Abort stops the run. A curve in an uneditable LAS file cannot be replaced and is reported as a failure.

The final summary gives the processed count and names, lists wells skipped for an insufficient checkshot or a declined replacement, and identifies wells left unprocessed after a stop or failed with a reason.
