1.What is the Strat Filter?
In the Strat Filter you can create custom parent-child filters between different stratigraphic , and other data types.
You With the Strat Filter you can select a ‘parent' stratigraphic unit (eg a Group) and then toggle through various ‘child’ data types. On the map you will see which 'child’ zones are present inside the parents top and base.
Child zones are drawn on the map as bars, displaying the top-to-base order in which they appear in the wellbore. The bars are annotated with unit name and thickness in MDMeasured Depth.
How to use the Strat Filter
The Strat Filter is located in the Windows tab in the top ribbon.

3. Creating a basic stratigraphic filterA basic filter will visualise on MapView the presence and thickness of a chosen stratigraphic
zone.To create a stratigraphic filter you will need to:
1) Select a chosen unit from the drop-down boxeswhat data you wish to display on the map.
2) In the Display drop-down, select the same data type that your chosen zone belongs to
The example below shows FANGST Group, with Groups selected in the Display drop-down.
To the right is a list of all wellbores returned by our basic filter.
...
On MapView, you will see the results of your filter visualized as bars, annotated with zone name and thickness (MD)
The bars are dynamically sized based on the range of thicknesses returned by the filter.
Wellbores which return a negative result are greyed-out.

Creating a Parent-Child Filter
Creating a Parent-Child Filter will allow you to visualize a data type (eg 3rd ord sequences) present inside a stratigraphic zone of interest (eg GARN formation).
Select a chosen Parent zone from the drop-down boxes.
In the Display drop-down, select a Child data type you wish to filter
In Display Filter Range choose All Zones, Upper or Lower
The example below shows the filter result of Garn combined with 3rd Order Sequences.
You can view other child combinations by simply selecting another data type in the Display drop-down, and conversely you can select another Parent while keeping your child filter.
...
Select the zone you wish to display that data for.
The selection below shows the Formations in the Fangst group. The Strat filter will also display a list of all wells containing the selected zone.
The data will be shown on the map as bars indicating the thickness (in MD) of every formation in the selected group (or other zone selected).
It is possible to select the same category displayed data and zone, this will result in a single bar showing the thickness of that zone (in MD).

Note: if a formation is only partially in a zone (e.g. the Jurassic) only that part of the formation will be displayed. Formations may be thicker than displayed if limited by the visualized zone. |

4. Display Filter Range
Display Filter Range allows you to view different depth ranges of your filter.
By clicking All Zones, you will view all Child zones present in your filter result.
Upper will return the shallowest Child zone in your filter result.
Lower will return the deepest Child zone in you filter result.

*Note that Upper and Lower are calculated using Measured Depth. |
