Conceptual Model
The Conceptual Model panel is used to build a structured geological framework from existing project data. It does not store new data – instead it links objects from the Data Manager to geological objects that can later be used in Structural Modeling.
The Conceptual Model is domain-independent: a single framework can reference both Time and Depth data at the same time. The domain is not chosen here – it is applied later, when the framework is used in Structural Modeling, where only the data matching the selected domain is used.
The panel is docked on the right side of the g-Space window, tabbed together with the Data Manager, Object properties and Visual Settings panels. (The View Manager is docked separately, alone, on the left side of the window.)
Geological Objects
Create and organize geological boundaries in top-to-bottom order. Each object represents a geological level (a horizon, an unconformity, or an intrusion) within the conceptual framework of the reservoir. Right-click in the tree to Add Object, Add Object Above or Add Object Below a selected object, Rename it, or Remove Object.
The tree is shown with the columns Object / Data, Type, Conformity, Direction and Stratigraphy. Object rows carry the Conformity and Direction values, while each linked data row shows its detected Type.
Linked Data
Drag objects from the Data Manager and assign them to a geological object. Time and Depth maps, horizon points and horizon maps (Time or Depth), Multi-Z surfaces (Time or Depth), attribute maps, and Markers (shown as "Well Picks" in the panel) can all be linked, so that one geological object combines several data representations. The type and domain of each dropped item are detected automatically and shown in the Type column.
Each object may hold only one item per data type. Dropping an unsupported item type shows a warning and is ignored; dropping an item whose type is already present asks for confirmation before replacing the existing one. Items can also be linked without dragging: right-click an item in the Data Manager and choose Assign to Conceptual Model (or Remove from Conceptual Model). Right-click a linked data row and choose Navigate to Data Manager to jump back to the source item.
Conformity
Define the boundary type for each geological object:
- Depositional – a conformable boundary that follows normal deposition.
- Unconformity – an erosional or non-depositional surface that truncates older layers.
- Intrusion – a body that cross-cuts the surrounding stratigraphy.
Direction
For unconformities, define whether the object is Top truncated or Bottom truncated. This controls how the surface interacts with the layers above and below it during structural modeling. By default no direction is set.
Stratigraphy
Right-click a geological object and choose Set Stratigraphy... to associate it with a chronostratigraphic zone from the project's stratigraphy columns. The dialog shows one cascading combo box per stratigraphy column, from broadest to narrowest. Choose Clear Stratigraphy to remove the association.
When a marker is assigned to a geological object as Well Picks, g-Space compares its age with the project's current stratigraphy. If a matching zone is found and the object has no valid stratigraphy, g-Space fills the object's Stratigraphy value automatically. An existing valid assignment is preserved and can still be changed with Set Stratigraphy....
Fault Model
Optionally link one global Fault Model to the conceptual model. Only one fault model can be linked; assign it by right-clicking a fault model in the Data Manager and choosing Assign as Conceptual Model fault model. When present, this fault model is preselected as the default in the Structural Modeling wizard, where the fault framework is taken into account when the structural model is built.
