SAN ANTONIO -

The Eagle Ford Shale oil boom is not only attracting businesses from around Texas -- but business from around the world are showing interest.

One company from Mexico was visiting members of the Eagle Ford Consortium to try to get their foot in the door.

Tritursa is a company that mines Baryte sulfate. The crush rocks into a powder-type substance.

"It's kind of a sealer and for people doing fracking jobs. This is poured in and it seals and it creates a cast in the holes to prevent any leakage," said Tony Castaneda, the interpreter for members of the ownership team.

"It’s a very promising business. It's very big with a lot of potential,”" said Diomar Jaime Perales Morena, part owner of the company.

Members of the ownership team are trying to spread the word about their company.

There were also representatives of companies from Canada and Taiwan.

"We get a lot of calls wanting to find out what it would take to engage in a business level in different parts of the shale," said Leodoro Martinez, Chairman Eagle Ford Shale Consortium.

There has been so much interest in the Eagle Ford that since 60 members joined the consortium in November 2010, it has grown by hundreds.

So much attention has drawn protests, however. 

While the consortium was meeting inside the Grand Hyatt on Thursday, a handful of protestors were gathered outside, chanting, "Hey hey, ho ho, fracking’s got to go.”

Fracking is the method used to extract oil and natural gas.

The protestors claim the process is contaminating the water and the air and there should be more regulation when it comes to disposing of fracking water.

“We don’t want to see the air we breathe. We want to keep it clean and want to make sure we bathe in clean water and drink potable water,” said Antonio Diaz, with the Texas Indigenous Council.

“The oil and gas play in South Texas is not going to go away,” Martinez said. "It is very important to find common solutions where there are identifiable problems."

Diaz said he would like to see more regulation when it comes to disposing of the fracking water.
