Final answer:
Enron Corporation continues to operate its oil and gas business today under the name "EOG Resources."
Step-by-step explanation:
The energy company, subject of the documentary "The Smartest Guys in the Room," that continues to operate its oil and gas business today under the name "EOG Resources" is Enron Corporation.
Enron was an American energy company that was one of the largest and most successful corporations in the United States. However, it collapsed in 2001 due to accounting fraud and corruption.
After the collapse, Enron's assets and operations were sold off, and one of the successor companies that emerged from the bankruptcy was EOG Resources. EOG Resources is now an independent oil and gas exploration and production company.
