It's convention season in Houston. Following the NRA convention's visitors from across the country -- Houston now welcomes visitors from all over the planet to the Offshore Technology Conference.
The annual OTC is the world's largest drilling technology meeting and Houston energy industry attorney J Wayne Ballew says this kind of tech changes faster than computers and smart phones.
"The technology of the industry and the way it advances is, I think, second to none."
Ballew says thousands of companies from over a hundred countries are all looking to the future.
"There's kind of an underlying theme this year of the 'next generation' with these companies and what they're gonna be faced with and what their role is going to be in the industry."
More than 80,000 are expected to attend -- including the Crown Prince and Crown Princess of Norway.
