Surreal Underwater River Landscape

A hydrogen sulfate enriched salt water layer (probably formed from decaying organics) at about 90′ within a cenote in Mexico has produced a surreal underwater river landscape.  The video gets very interesting after the 3:15 minute mark.

New Capability Added To RockWorks16 For Automatically Computing Horizontal Well Path

This video describes a new capability whereby RockWorks16 can be used to automatically determine the path for a horizontal well that starts out as a vertical borehole at a designated location and then curves (based on a user-defined radius of curvature) into a pay-zone as defined by two grid models.  The path will then automatically route itself along the mid-line of the two surfaces until reaching a user-defined point.

Caveat: This program assumes that hole starts out vertically.

How To Export Diagrams From RockWorks16 Into Google Earth

Two new videos showing how to export diagrams from RockWorks16 into Google Earth have been uploaded to YouTube.  The short version is 2 minutes and skips all of the “how-it-works” information.  The long version is 12 minutes and provides a description of what goes on “behind the scenes”.

Please note that these videos do not cover the EarthApps portion of RockWorks which directly exports to Google Earth.  Instead, these videos show how to export existing 2-D diagrams (maps, profiles and sections) from RockPlot2D and 3-D diagrams (logs and block models) from RockPlot3D into Google Earth.

More Sinkhole Madness

Several questions about this video;

(1) How did the cameraman stay so steady and avoid the natural impulse to run away?

(2) How did the cameraman keep from muttering an expletive?

(3) When will these sinkholes stop eating cars, trees, houses and resorts?

Strange Log Appears Far Above Other Logs When Hanging Section on Selected Stratigraphic Horizon


If you’re hanging a section relative to a stratigraphic horizon within RockWorks16, and you see a strange log floating way above all of the other logs, here’s what’s going on …

The offending borehole does not contain any reference to the stratigraphic unit (in this example, the top of the Potosi Formation) that was selected as the datum.  As a consequence, it remains at it’s correct structural elevation while all of the other logs have been vertically offset such that the datum contact is adjusted to an elevation of zero.  In other words, the program is working just fine – but a fat lot of good that will get you.

Here’s the solution …

Step 1.  Zoom in on the offending log …


Step 2.  Make note of the log ID.  In this case, that’s “DH-05”.  This, of course, assumes that you have elected to plot the log titles within your cross section.  If not, turn on the titles and try again.

Step 3.  Uncheck the offending log within the Borehole Manager database.


4.  Re-run the cross-section program …


5.  Be happy.
