82 - BOOK 1 - WELLCAD BASICS 1.4.2.1 LAS Import www.alt.lu [Alias] Gamma=GR, Gam, GR[api] Caliper=CAL, CAL[mm] … [DefaultUnit] GR[api]=api CAL[mm]=mm … The Log ASCII Standard (LAS) file format has been developed and promoted by the Canadian Well Logging Society. For more details of the format refer to the CWLS homepage (www.cwls.org). WellCAD currently supports the import of LAS files up to version 2.0. To import a LAS file choose File > Import > Single File and select the file type LAS Files (*.LAS). A LAS file contains header information and as you will learn in paragraph 1.4.3 Header and Trailer the WellCAD header can be filled with this information. It is assumed that the WellCAD header contains the necessary slots to host the header data. At import time WellCAD will try to match the header entries of the LAS file with header fields of the current Borehole Document header. The following dialog box is displayed to allow matching of header words.
List of data channels contained in the LAS file BOOK 1 - WELLCAD BASICS - 83 In the WellCAD Header Form section (lower right) select the header from you would like to use. The Name, Description and Value columns show the information coming from the file header. The Header Field column is populated from the selected WellCAD header. In order to transfer the header information (Value) from the file header to WellCAD the header labels used in WellCAD (i.e. the Title of the dynamic text fields defined when designing the header in HeadCAD) must match. You can click into a cell in the Header Field column in order to select from the labels available in the WellCAD header. To exclude header information from being imported simply remove the check mark in front of the row (or use the Deselect All button). Click the Skip Header button to pass over the header information import. The next dialog box displayed lists the contents of the LAS file. From the Logs To Import list the user can select the data channels he would like to import and can restrict the depth interval from which the data will be read. Once the users clicks the OK button one Well Log or Mud Log will be created for each data channel. The type of log created depends on whether the incoming data has been sampled at a constant rate or not. If the Step field of the LAS header has been set to zero, the incoming data will always be imported as Mud Log. If the Step entry is not zero, WellCAD will perform a scan of the data and compares the imported depth of two consecutive data values with the sample rate specified in the LAS header to guarantee a constant step. If a mismatch is detected a warning message will be displayed to inform the user that the data will be imported as Mud Log instead as Well Log.
