Adding Borehole to Established Cross-Section

Recommended Posts

Quantum    0

Hi,

I have created a cross-section using subsurface analyst a few months ago. Last week, a new borehole was drilled and we would like to add the borehole, lithology, as well as the geophysical log to the cross-section. I have not been able to figure out a way to add a new borehole to an established cross-section. If anybody has an efficient way of accomplishing this task I would love to hear your methods!

Thanks so much!

I would take a look at the "Advanced Cross Section Editing" tutorial at http://aquaveo.com/software/ahgw-learning-tutorials

Assuming you've already generated an XS2D cross section for a particular SectionLine, and you want to add to it:

First off, I would add a new point to the Well feature class at the location of your new borehole. Make sure it has a unique HydroID value. This is done in your plan view data frame, not XS2D cross section.

Then, add your borehole information to the BoreholeLog table. There should be one row for each hydrogeologic unit. The WellID attribute for the new BoreholeLog rows should have the same value as the HydroID for the new well you created. For the BoreholeLog table, make sure the HGUID, TopElev and BottomElev fields are filled out.

So, for example, Well has a new feature point, with a HydroID of 1234567 (or some other unique value). The BoreholeLog table will then have multiple new rows for each hydrogeologic unit in the borehole, with the WellID value being 1234567 (or whatever you used for HydroID on Well), and the top and bottom elevations and HGUID fields populated.

Now, make sure you're in the Arc Map Data Frame with your Well features, SectionLine features, and BoreholeLog table. You want this Data Frame to be active, not the one for your XS2D cross section.

Select the SectionLine you're adding to, along with the new Well feature you just created. ***** This is vital to adding to an existing cross section ***** The tool will work off selected well features, so if you're adding one or more wells/boreholes, then you want to select just the ones you want to add.

Open the "Create XS2D Boreholes" tool (in the Subsurface Analyst, XS2D Editor toolset). Choose the appropriate Section Line layer, and enter the appropriate HydroID value for the SectionLine you're adding to (the Identify tool works great for this). Choose the same XS2D_Catalog table that you used before (you're probably only using 1, and the default name will be XS2D_Catalog). Choose the appropriate Well feature class, where you added the new well and assigned a unique HydroID value. Choose the appropriate Well HydroID field (it's optional, but in this case, where you're adding to an existing cross section, you'll want to use it). Choose the appropriate BoreholeLog table, and its WellID field. Choose the XS2D Boreline layer you want to add to. By default, it will be named XS2D_Boreline_.... with the HydroID of the original SectionLine in the name. For example, XS2D_Boreline_6475. You can just go to your XS2D cross section data frame, and look for the name there. Finally, make sure the "Overwrite" toggle is not checked. We want to append to the XS2D boreline layer, not overwrite everything in it.

Once you run the "Create XS2D Boreholes" tool, you should see the new XS2D Boreline features appear in your XS2D cross section (you probably have to activate its Data Frame to see it).

At this point, you'll probably have to update your XS2D Panel features to reflect the new borehole. See section 8 in "Advanced Cross Section Editing" tutorial on how to do this. This is simply using the ESRI tools to create or edit polygons.

For adding geophysical log plots to existing plots, you can do basically the same thing with the "Create XS2D Geophysical Plot Features" tool.

See the "Adding Borehole Log Plots to Cross Sections" tutorial for more info.

Add new Well features if necessary. You don't need to do this if you are adding a geophysical log for a Well you just created (like above) or for a Well that already exists in your data.

Add new data fore this borehole to your table containing your geophysical log information. In the tutorial referenced above, the table is called LogData. All you need here is to enter the WellID, Depth, LogValue, and FType.

WellID should match the HydroID value of the matching Well feature.

Depth is the depth of the reading.

LogValue is the value of the reading.

FType is a description of the type of data (ex: gamma)

Finally, in your Data Frame with your Well features, select the Well feature(s) with the new geophysical log data you wish to plot.

Open the "Create XS2D Geophysical Plot Features" tool. Enter all of the information necessary to run the tool. Make sure the "Append Features to Feature Classes" toggle is turned ON. Be sure to expand the "Plot Options" category at the bottom. You will have to play with these values in order to plot the data to the size, position, etc. that you want.

When you originally created your data, you probably used one of the wizards for creating the cross section and geophysical data. These wizards basically run the geoprocessing tools mentioned above, without you having to worry about all of the inputs. They first create all of the necessary Data Frames, XS2D feature classes, etc. before creating the new features.

You won't be able to use the wizards to add to existing data, and you might have to play with the "Plot Options" category for adding geophysical log plots to make them look like the existing data (same size, layout, position, etc.)

You could use the wizards to totally generate the data again from scratch, but this will not keep any additional edits you've made in the meantime, like adding XS2D Panels, for example.

However, if you're saving the geoprocessing history with your Arc Map document, you could simply use the geoprocessing tools with the same inputs and settings to your advantage. For example, the wizard to build geophysical plot features calls the "Create XS2D Geophysical Plot Features" tool. If you look in your history, you should see it there after running the wizard (if your Geoprocessing Options in Arc Map are set up to save it in your history). If it is in your history, and you want to use the same plot options (size, positioning, etc.), just select the new Well features with geophysical plot data that you want to add, the open the "Create XS2D Geophysical Plot Features" tool from your geoprocessing Results tab, and review all the information there before running your tool. Just be sure that your "Append" option for the tool is turned on.

Wow Doug!

Thanks so much for the very quick and thorough response! I will follow your steps and let you know how it goes.

I never thought about checking the geoprocessing history for the geophysical plot options. I have been using a spreadsheet I created to keep up with those formatting options.

Thanks again!
