RockWorks | Borehole Manager | Stratigraphy Menu
Unlike lithology data, which represents observed rock types which can repeat in a borehole and be inconsistent in order, stratigraphic data represents organized formations, consistent in order between boreholes, and non-repeating within a borehole. RockWorks uses surface modeling or gridding tools to illustrate the stratigraphic layers. Because surface models are created for these diagrams, you must have stratigraphic data for at least 4 boreholes.
Use the tools in the Borehole Manager Stratigraphy menu to interpolate and visualize your stratigraphic data in a variety of ways, listed below. For many of the diagrams (both 2D and 3D) logs can be included.
Feature Level: RockWorks Standard and higher
Structure Maps - Isopach Maps - Modeled Stratigraphy Diagrams - Model-Based Computations
| 2D Structure Maps Grid and contour a selected formation. A variety of map layers are available. |
 |
| 3D Structure Maps - 1 Formation Create a grid and 3D surface of a selected formation. |
 |
| 3D Surfaces of all Formations Create grid models and 3D surfaces for the tops of all formations in the project. |
 |
Isopach Maps: Create a grid model for the top and for the base of a formation or adjacent formations, and create the following displays.
| 2D Isopach Map Display the thickness as a 2D contour map, with a variety of map layers available. |
 |
| 3D Isopach Display the top and base surfaces in 3D with side panels. |
 |
Modeled Stratigraphy Diagrams: Interpolate surfaces for the top and base of all formations, or read existing grid models; the following display options are available.
| 3D Stratigraphic Model Formation top surfaces, base surfaces, and side panels are displayed in 3D. |
 |

| 3D Modeled Fence Diagram - Shapefile "Sliced" between multiple points in the study area and exported to a 3D Shapefile for use in ArcScene. |
 |
| 3D Straight Fence Diagram - Shapefile Drawn as straight-line correlations between boreholes, exported to a 3D Shapefile for use in ArcScene. |
 |
| 2D Geology Map - Surface Represents stratigraphic units along a specified surface model |
 |
| 2D Geology Map - Plane Represents stratigraphic units along a horizontal slice plane |
 |
Model-Based Computations: Create a detailed report (of volume, mass, nodes, percent) for your project's formations, based on either a solid- or surface-based stratigraphy model.
| Compute Formation Volumes - Solid Based a solid-model (.RwMod) version of the stratigraphic model. |
 |
| Compute Formation Volumes - Surfaces Based a surface-model version of the stratigraphic model. |
