WellCAD Multiwell tutorial

background

In the following steps, you will learn how to create and configure a new Multiwell workspace. We will walk through inserting and setting up a basemap, importing borehole coordinates, and visualizing your data via a section view. You will also learn how to link markers, add new markers, assign lithology, and flatten your cross-section for more efficient analysis.

By the end of this tutorial, you will have a clear understanding of how to set up a WellCAD project and effectively manage your borehole data. Let’s get started!

Creating a New Document

  • Open WellCAD, go to File > New or select New Field Document from the start page.

Adding a Basemap

  • Insert a basemap file (with defined coordinates).
  • Enter Top (North), Bottom, Left (West), and Right coordinates to position the map.
  • Use zoom tools to fit the map on-screen.
Basemap workflow.

Inserting Boreholes

  • Select Edit > Insert New Boreholes and choose multiple files with Shift+Ctrl.
  • Initially, coordinates are all set to zero.
  • Use Edit > Import Borehole Coordinates to load the correct X, Y, and Z from an ASCII file
Insert boreholes.

Creating a Section Line

  • Activate Section Mode.
  • Shift+click in sequence across boreholes to create a section line; release Shift and click again to confirm.
  • Switch to Section View to see the boreholes along that line.

Markers and Surfaces

  • Brown lines in boreholes represent markers/surfaces.
  • Use Edit > Link Markers to link identical markers across boreholes.
  • Edit > Add Markers from Surfaces to add missing markers.
  • Insert Surface to add a new marker; name it, choose style, then Shift+drag it across boreholes.

Assigning Lithology

  • Double-click between markers to assign a lithology pattern.

Flattening the Section

  • View > Flatten Surface flattens the section based on a selected marker; View > Unflatten Surface reverts it.
