"I think the impact of the 9/11 terrorist attacks on our industry is similar to their impact on everyone's everyday lives," he said. "Just like we have to decide where to go on vacation or business, oil companies must decide where they will invest their capital. It's impacted oil producers' decisions on their capital investments; there are places they may want to invest because of the resources there, but they can't because it's too risky."

Bill Vanderland, special agent with the Federal Bureau of Investigation, said his office has done a lot of work with local companies and given innumerable briefings over the last five years on what to look out for and "to increase their comfort level and to let them know we'll be there to respond to any event, whether it's a terrorist act or a disgruntled employee."

"In our briefings, we've stressed the fact that we don't see this as protecting the oil fields from al-Qaida; there are other threats like disgruntled employees, environmental extremists or just lone nutcases," he said. "We point out that suspicious activity is suspicious activity regardless of race, ethnicity or gender."

Mark Rankin, vice president of risk management and marketing for Basic Energy Services, said his company has noticed two developments since the attack.

He said he has noticed that midstream and downstream companies which operate facilities like pipelines are implementing additional background checks on their vendors "possibly stemming from Homeland Security regulations. We've also seen some increased work around our insurance policies where they ask us to sign off if we're declining terrorism coverage."

He feels confident a company like Basic, engaged in the services it offers, is not a top security concern. Rather, he said, companies that operate larger facilities or offshore facilities are being impacted by new security regulations.

The attacks, said Rick Rainey, spokesman for Texas Eastern Products Pipeline Company (TEPPCO), the midstream company with assets in the Permian Basin, raised awareness in the industry for the need for strong security measures.

While security has always been a top priority for the company, he said, in the wake of 9/11, TEPPCO has worked to train its employees to be vigilant and look for signs of possible problems and how to respond to problems. TEPPCO has also worked with the fire and law enforcement officials in its communities, educating them on the company's operations and even participating in training exercises.

"Besides Midland, we have infrastructure in Midland and work with the Office of Pipeline Safety and Department of Homeland Security, keeping them aware of what we're doing," he said.

Vanderland said the FBI's efforts in working with oilfield employees on have begun having the collateral effect of impacting issues like oilfield theft, which he said is significant because oilfield equipment is so valuable these days.
