Beyond fracking: University of Wyoming scientists look for ways to boost oil and gas production

(Continued)

WYOMING —

“When I started in the industry, we used to call it throwing projects over the fence,” said Mark Northam, director of the School of Energy Resources. “Geologists would start with it, do the best job they could and then throw it over the fence to the engineer. The engineer would get a geologic model and go ‘wow, that’s a great geologic model but I can simulate that. That’s too complex.’”

And then the pair would begin arguing.

The idea is to get chemists, geologists, petroleum engineers, physicists and computational scientists – to name a few – speaking the same language, Alvarado said. Something is lost in translation when, say, an engineer is trying to describe a problem to a chemist. The two understand a different problem and thus work towards different solutions.

“It’s not so much about being a generalist as about being multilingual person able to communicate with specialists,” Alvarado said.

The Improved Oil and Gas Recovery program comprises four faculty members from the chemisty, geology, chemical engineering and chemical and petroleum engineering departments. Such an approach is becoming increasingly common in industry, as teams of scientists approach challenges on a project or programmatic basis.

Things get more complicated when it comes to the actual science that might boost production levels. Alvarado likes to talk about “challenging the paradigm” of oil and gas production. What does that mean exactly? Traditionally, as oil fields mature operators turn to what are essentially cleaning solutions to glean oil stuck to the rock. But instead of cleaning oil from the rock, Alvarado and his team are focusing on how to improve oil mobility. Basically, they want to improve oil flow so more of it flows out of the reservoir. Doing that requires fine-tuning of the chemical concoction injected into the reservoir, he said.

  • Beyond fracking: University of Wyoming scientists look for ways to boost oil and gas production

    Terms like horizontal drilling and “fracking,” as hydraulic fracturing is commonly referred to, are well known now. The two technologies have sent U.S. energy production soaring in recent years, as previously inaccessible reservoirs of oil and gas have been unlocked in places like North Dakota, Pennsylvania and New York.

  • More oil and gas drillers turn to water recycling

     When the rain stopped falling in Texas, the prairie grass yellowed, the soil cracked and oil drillers were confronted with a crisis. After years of easy access to cheap, plentiful water, the land they prized for its vast petroleum wealth was starting to dry up.

  • OERB web.tiff Industry funded nonprofit cleans abandoned sites

    The energy industry has changed somewhat dramatically over the last two decades. During the boom in the '80s, regulation was scarce and energy companies left behind machinery and concrete slabs in the wake of their excavating. 
    Since 1993 the Oklahoma Energy Resources Board has been working diligently to make amends for the environmental damage done during this era, and 20 years later OERB has managed to clean up 13,000 well sites across the state including 53 in Grady County.
