Frac Sand Mining
Sand has been mined in Wisconsin
for some time now but with the recent invention of Horizontal Drilling, we are
able to access more oil and gas than ever before. One common technique of
extracting that oil is hydraulic Fraccing. Hydraulic Fraccing is the process of
drilling and pumping water, chemicals, and Frac sand into the ground at a high
pressure. This causes the shale beneath us to crack and the Frac sand is then
used to hold those cracks so that we can extract oil from places that were not
accessible before. Now we have been using this technique for a while but now
with horizontal drilling we are able to drill one hole into the ground and when
we get to the appropriate depth, we have numerous pipes shooting out in all
directions that can then recover much more oil than before.

Now Frac
sand is more than just the run of the mill quartz we are used to. It is high
quality quartz that is of a specific size and is very resistant but smooth and
round. This sand is found in abundance in the sandstones of Wisconsin,
specifically western Wisconsin. As you can imagine, this has caused a frenzy to
mine that sand for economic gain. Some have made of quite well while others
have not. Proponents argue that the mining of this sand is good for the local
economy as well as the state and federal economies too. Opponents say that the
process of mining the sand is bad for the environment and will destroy
landscapes that have stood for hundreds of years. This argument has pitted families
in Wisconsin against each other and has created many Hatfield and McCoy type
scenarios. It gotten to the point of where so many people are so one sided for
one side or the other that they have become blind to the facts and base all their
arguments purely on emotion.

However,
luckily for us we have GIS! In this blog we will use GIS to help us answer some
basic questions around Frac sand mining. Using GIS our class will investigate
many aspects of Frac mining from transportation to prime locations for mines.
This class project will remain subjective in the sense of what we are studying,
but you will periodically hear my opinion on the subject matter. So join me in
exploring the variety of tools in ArcGIS that we can use to study Frac Sand
Mining in Western Wisconsin, specifically our study area of Trempealeau County.
