Import Mode
|
These options control how Petra handles overlaps between curves already in the project database and the LAS file. The Add or Replace option allows for the creation of new logs and will completely replace any overlapping curves in the database with the LAS file data. Add New Logs Only only creates new logs; when there is an overlap between the database and the LAS file, the database won't change. Merge into Existing Logs does not create any new curves in the database, and will merge data from the LAS file with the curves already in the database. This merge operation can either prefer old values, non-null new values, or all new values. Add or Rename allows for the creation of new logs, and will rename overlapping curve names with a numerical suffix (like GR_1). For this example, select Add or Replace Logs.

Load Complete LAS HEADER Section as a Text Block
|
stores the log header as a block of text.
|
|
Enable Sample Rate Round Off Correction Algorithm
|
Problems with rounding usually cause missing depths in the curve. This option corrects for depth round off errors caused by a non-standard sample rates (such as 0.1524), which are usually a consequence of converting logs measured in one depth unit into a different depth unit.
|
|
Disable Error Scanning and Repair
|
By default, Petra scans for potential bad characters in the curve data and looks for data that is not space delimited. These conditions are not corrected if this option is checked.
|
|
Interpolate Missing Depths
|
This option interpolates values over missing intervals in the LAS file. This interpolation simply repeats the last good value. Note that there are more interpolation options inside Petra'spreview window available in the Main Module.
|
|
Remove Special Characters From API Number
|
This option removes any non-numeric characters from the API number in the LAS file. Embedded blanks are converted to underscores prior to matching wells in the database.
|
|
Scan Depths and Use Minimum Sample Rate Found
|
Scans the depths and determines the minimum sample rate.
|
|
Append Following Source To Curve Name
|
Appends text to the end of the loaded curves names.
