From the President
Linked at the roots to Boots & Coots
By Dave Lesar, chairman, president and CEO

Sometime this summer, it’s our intention to welcome Boots & Coots to the Halliburton family. Combining its talents with ours will be a great fit, and a natural outcome for two companies that have a shared heritage in the oilwell services business. Boots & Coots provides services from pre-engineering, planning and prevention services to well completion, re-entry and repair, and emergency response and mitigation. “Confidence under pressure” is the company’s watchword, and that alone points to our matching cultures.

Boots & Coots traces its roots to Myron Kinley, who, with his father, was the first to put out a well fire using explosives. That was in California in 1913, a few years before Erle P. Halliburton started his company in Oklahoma. The young Kinley started his own company, the M.M. Kinley Company, in 1923, taking it to international fame in 1931, when he went to Romania to put out a fire that had raged for two years. The caved-in well had made a crater 250 feet wide and 65 feet deep, filled with ground fires and a web of melted pipeline. It took Kinley six months to lick the fire.

A tough, determined well-fire fighter named Paul “Red” Adair joined the M.M. Kinley Company in 1946, followed in the next several years by Asger “Boots” Hansen and Edward Owen “Coots” Matthews (who joined Kinley after working at Halliburton for 10 years).

After nearly 14 years with Kinley, Red Adair formed the Red Adair Company, and Boots Hansen and Coots Matthews signed on with him within a few years. Their first job as Red Adair Company was in Hull-Daisetta, Texas — and the referral came from one of Coots’ old friends from Halliburton.

On average, the threesome and its team controlled more than 42 oilwell fires and blowouts per year, inland and offshore, all over the world, including the “Devil’s Cigarette Lighter” in Gassi Touil, Algeria, in 1961.

In 1978, Boots Hansen and Coots Matthews left the Adair Company to form Boots & Coots. In 1990, Boots & Coots was the first oilwell fire-fighting company contacted by the Kuwaiti government to battle the oilwell fires ignited in Kuwait at the close of the first Persian Gulf War. Boots & Coots specialists arrived in Kuwait at the end of February 1991, and, at the completion of the job, they had capped 128 of the most difficult wells.

When Red Adair retired in 1994, he sold his company to Global Industries. A short time later, the senior management of the Red Adair Company formed International Well Control (IWC). The new company’s path intersected with Halliburton’s when the two joined forces to create the WellCall Alliance. A few years later, Boots and Coots sold their company to IWC, which, wisely, kept the legendary name, “Boots & Coots.”

From 2001 through 2009, Boots & Coots followed a purposeful growth path, with acquisitions and expansions that broadened the company’s offerings to include every aspect of well control and fire prevention, as well as a pressure control tool rental business.

Obviously, our two companies have deeply intertwined histories. As we look forward to combining our talents, resources and cultures, I believe the most satisfying aspect of this process will be getting to know our Boots & Coots colleagues. I will keep you informed as we move closer to finalizing this exciting new relationship.

Please keep in mind: There are guidelines and restrictions regarding communications between Halliburton and Boots & Coots employees between now and the closure of this transaction, and as the two companies form planning teams regarding the integration. Beverly Stafford, director of Mergers and Acquisitions Integrations (and a 2009 graduate of the President’s Leadership Excellence Program), will lead these efforts for Halliburton. Please contact her if you have any questions about what is permissible during the next few months.

The merger is expected to close in the summer of 2010, subject to regulatory approvals, approval by Boots & Coots’ stockholders and other conditions set forth in the merger agreement with Boots & Coots.

As always, if you have anything you’d like to discuss, please contact me.
