140 - BOOK 1 - WELLCAD BASICS www.alt.lu Resample with a constant sample rate: In order to up- or down-sample the data in the selected Well Log(s) enter a new sample rate into the corresponding edit box. If necessary interpolated data values will be inserted. Use sample rate of a reference log: Sometimes it might be required to extract data from a Well Log at distinct depth locations (e.g. positions where plugs from a core were taken and detailed core analysis results are available) and store the results in a new Mud Log. The process will create a new Mud Log with depth positions being derived from a reference log. The reference can be selected from the corresponding drop down list. Mud or Percentage Logs can be chosen. As the requested depth location could fall between two samples of a Well Log the user has the option whether to take the nearest value or get an interpolated value. Well Log to resample Reference Log Resulting Mud Log Reference Log (left) provides the depth positions at which data from the original log (middle) will be extracted and saved into new Mud Log (right) 1.5.9 Creating Blocked Curves This process allows calculation of statistical values, such as average, standard deviation, minimum and maximum, of Log data for given depth intervals. The results are output either as text (Comment Log) or graphics (Interval or Percentage Log) depending on the input log type. The intervals of calculation are read from a reference log or can be entered by the user. Any log dealing with depth intervals – storing a top and a bottom depth as data – can be used as reference log.

Results are output as Percentage Log and Comment Log To block a log select the Block Process option from the Process > Common menu. A dialog box opens and provides options for blocking mode and input channels. Blocking Process Options
