About well correlation

As part of the data preparation process, you can use the Well Preparation strip (Prepare > Wells) to edit and prepare well log data and markers, including creating marker sets, developing TVT and TST projections and other miscellaneous tasks with markers and logs. Closely related to this set of marker and log functionality is the Well View, where you create cross sections through your wells and zones of interest and perform marker picking, along with analysis of log and surface data.

If you have a large number of wells, you may find it useful to group and filter them so they are easier to find. See Organizing your wells with grouping and filtering for details.

The functionality available in the strip is grouped as follows:

  • Marker Tools Tools for creating marker sets, deriving markers from the stratigraphy or surfaces, merging marker sets and adding rates to marker sets.
  • TVT/TST Calculate properties for and create TVT and TST projections that can be displayed in the Well View.
  • Log Tools Edit, merge and smooth logs.

The Well View

The Well View is the most important type of display for detailed QC and analysis of well log information. In addition to well log correlation and marker picking in the view, you can perform the following in a Well View:

  • Well matching  (can be performed at different stages during modeling): You can see mismatches between markers and their respective surfaces. For more info on well matching during data preparation, see Depth Well Matching in the Post-Processing Tools strip.
  • Zone definition  (part of reservoir definition): The definition of stratigraphic hierarchy used by volumetric assessment and reservoir modeling/flow simulation is best done with the relevant logs displayed in the Well View.
  • Volumetric preparation and reporting  (part of volumetrics): The analysis of fluid observations to enable definition of fluid contacts for volumetric assessment or saturation definition for dynamic simulation can best be done in Well Views configured as Fluid Distribution plots.

The Well View is an interactive view, you can use the JewelExplorer to display wells, logs and markers in the view for QC and analysis purposes. It also includes functionality such as the ability to display data using TVT and TST scales, filter data in the view by depth, zone or log, and display fault gaps, overlap, and inflection points in the tracks. See Well View for more information.
