From-To Function

"From-To" pairs establish pairs of depths on a well.  These points are useful in a variety of functions, including shifting log curves, pay intervals, and fault gaps.  

To create From-To pairs, select the "From-To" button on the Fm Top Correlation Toolbar.  Alternatively, select Logs>Start Picking From-To Pairs on the menu bar at the top of the CrossSection Module. Left click once at the top of the interval and again at the base of the interval.  Repeat to add more from-to pairs.  Right click to stop picking, or select Logs>End From-To Picking.  

The From-To pair tools are available from Logs>... menu at the top of the Cross Section Module.

For Digital Logs (uses the log curve indicated under the Logs menu)

• Depth Shift Log Curves
• Amplitude Shift Log Curves
• Interpolate Data Values

For Fault Gaps

Create Fault Gaps - This option adds new fault cuts based on the extents of the from-to pairs.

Shift Existing Fault Gaps - The "from" depth is used to identify an existing fault marker and the depth of that fault is set to the "to" depth.

For Pay Data

Pay Intervals (create) - This entry stores the From-To thickness to a selected zone data itme.ew pay data entries are added to the database for each interval.

For Perfs

Create Perfs - New perf entries are added to the database for each interval.
