25 years ago Evan Franseen stepped onto the rocky gravel of the southeastern coast of Spain, and was in awe of what he saw. He was looking at a historic landscape of preserved rocks millions of years old.
"My mouth just hit the ground," Franseen said.
When Franseen, Professor of Geology, began his Ph.D research of carbonate systems in 1984, he never imagined he would find a system of rocks so special.
"I have to pinch myself to believe that I lucked into this whole thing," Franseen said. "Everything we have researched; it is like an incredible dream."
Areas with this degree of preservation are rare, Franseen said. That is the reason he keeps going back.
"This is now a world famous area because the rocks are so beautifully exposed," Franseen said. "It resembles rocks covered by water. You almost feel like you are snorkeling around when you see this stuff. Everything is preserved."

"These exposed rocks are kind of like a natural classroom," said Bob Goldstein, Chair of the Geology Department, "allowing geologists to crawl around in."
The oil industry currently drills offshore in the subsurface, where rocks rich in oil and natural gas are usually located. Because the rocks are underwater they are not easily accessible and a drill can only penetrate a tiny hole, called a reservoir, Goldstein said.
"The rocks in Spain are actually exposed examples of reservoir rocks at the surface we can examine," Goldstein said. "These conclusions lead to finding a lot more oil and gas. Or at least finding it more easily."
Today, many oil companies are drilling the most expensive oil and gas wells in the world. Huge reservoirs of oil and natural gas have been discovered in offshore Brazil, Goldstein said. The rocks are so deep in the water they could cost $80 to $120 million to drill.
"The rocks we are working on in Spain look very similar to the ones in the subsurface of Brazil," Goldstein said. "There is a lot of excitement in investing in the research we do."
Franseen and Goldstein have been taking students and other researchers to the area for years. They also teach classes for the American Association of Petroleum Geologists in the area.
"People from the oil industry go over there and they will learn the basic principles of how these carbonate systems work," Franseen said. "That is what the oil industry is interested in. We can model and learn about these systems, go where the oil is, and then apply the research. This will allow for advances in producing oil more efficiently."
John Bova, Senior Research Associate at Exxon Mobil, first visited the area in 2005 through the American Association of Petroleum Geologists (AAPG). He now takes employees from Exxon Mobil to the area for research and training.
"I thought the area could be used as an analog for different types of fields we have been looking at," Bova said. "In the geology world we look for outcrop analogs. We can walk up to them and understand geology, whereas when you drill a well you can't really see what is going on."
Three groups of geoscientists from Exxon Mobil have visited the area. Bova said his objective is to introduce them to different types of geology in order to make interpretations.
"In addition to the training component we build a geologic model which will be published at this year's AAPG in Denver," Bova said. "In the model you can build a lot of different scenarios and simulate what positions to put wells in. That part will help us learn where to build subsurface fields."
Professor Franseen discusses his research in
Spain and how it will benefit the oil industry.
"It is not likely our research will directly affect global oil supply," Franseen said. "Oil is a finite product. There have been all kinds of predictions as to when it will run out."
Franseen said that although the U.S. has made advances in energy research, an end to the energy crisis is still far in the future.
"I think a lot of this green type stuff is attractive to all of us," Franseen said. "But we're just not there yet. I don't see anything yet that is our next alternative to fuel."
Natural gas is relatively clean and abundant, Franseen said, but despite advances in cleaner energy technology, the U.S. will still remain dependent on oil for many years.
"Oil is in everything we use," Franseen said. "Petroleum has issues with the environment, but as bad as those things could be we are still going to be dependent. So we need to keep finding and attaining oil."
Exxon Mobil will continue to conduct research in the area, but the company's agenda includes much more.
"We have a lot of big, important things to work on," Bova said. "In the scheme of things this is not even on the radar. On the local perspective, however, it is significant. I hope that this research will be the first of its kind."

"We are training students in these projects," Franseen said. "Then they go and get tremendous positions that can influence a new company."
CJ Lipinksi, graduate student, first visited the site in fall of 2006. He conducted research of carbonate systems, sedimentology, and stratigraphy of the area. Now Lipinski works as a geoscientist for the Chevron Corporation.
"The oil industry has a huge demand for geologists, and Bob and Evan will lead you quite strongly," Lipinski said. "I get to use all the science I learned."
The research Franseen, Goldstein, Lipinski, and many others have done will enable the oil industry to simplify models to better explore oil, Lipinski said. The site in Spain is a unique area for research and exploration.
"What is special about this area is that it is scaled down," Lipinski said. "You can visit a lot of different carbonate environments in a smaller area."
The project has received funding from the National Science Foundation, various oil companies, and recently a $250,000 grant from Exxon Mobil. The funding and support will allow Franseen to continue influencing both the oil industry and students through his research.
"What keeps us going is the hope that our work will have an impact," Franseen said.
