Szydlowski will join a new chief financial officer and board of directors, all of whom also were named Tuesday, to lead the company once it emerges from bankruptcy reorganization. Tulsa-based SemGroup is expected to exit Chapter 11 in November and become a publicly traded company.

“The new management team and board will be comprised of the best and brightest members of the midstream energy industry,” said Terry Ronan, the company’s president and CEO during its Chapter 11 reorganization, in a press release.

“Their experience, together with their many notable accomplishments, gives SemGroup a remarkable leadership team to execute its post-Chapter 11 strategies and build value for its stakeholders.”

Ronan will leave SemGroup after the restructuring is complete, a spokesman said.

Szydlowski, 58, has more than 28 years of experience in the transportation, management and production of refined fuel products. He most recently served as president and CEO of Colonial Pipeline Co. in Georgia.

Before joining Colonial in 2006, Szydlowski was recruited by the Pentagon to held rebuild the Iraqi oil sector.

Szydlowski has an MBA from Indiana University and a bachelor’s degree from Kettering University, formerly General Motors Institute.

Philip J. Reedy was named chief financial officer. Reedy most recently served as CFO of Citgo Petroleum, which was based in Tulsa until a few years ago when it moved to Houston. Reedy has

SemGroup plans to ask the U.S. Bankruptcy Court in Delaware to retain Szydlowski and Reedy as consultants to work alongside Ronan for the remainder of the restructuring. Szydlowski and Reedy are scheduled to attend the exit financing syndication meeting in New York on Sept. 10.

Among the new board officers, John F. Chlebowski has been selected as SemGroup’s chairman. Chlebowski currently serves as a director of NRG Energy Inc. He previously was president and CEO of GATX Terminals.

In addition to Chlebowski and Szydlowski, the new board will consist of: --Ronald A. Ballschmiede, executive vice president and CFO of Chicago Bridge & Iron Co. N.V.;

--Sarah M. Barpoulis, president and founder of Interim Energy Solutions LLC.;

--Stanley C. Horton, founder, principal owner and CEO of Semoran Holdings, LLC.;

--Karl Frederick Kurz, COO of Anadarko Petroleum Corp.; and

--Thomas R. McDaniel, retired energy executive.

SemGroup officials announced the executive search in May, forming a committee that included representatives from its bank lenders and unsecured creditors. The search committee worked with consultant Russell Reynolds Associates Inc.

Ronan, the current CEO, joined SemGroup in March 2008 as a finance executive. He was named top executive after co-founder Tom Kivisto was removed from the post shortly before the company’s July 22 filing for bankruptcy protection.

Kivisto was one of Tulsa’s highest-profile CEOs. Under his leadership, SemGroup became a significant donor to many local charities and was the co-sponsor of an LPGA golf tournament held annually at Cedar Ridge Country Club. That women’s professional event was canceled following the loss of SemGroup’s funding.

Fellow SemGroup co-founder Gregory Wallace was the original CFO. He also is no longer with the company.

SemGroup has been without an official CFO. Lisa Donahue has served as chief restructuring officer since her firm, AlixPartners, was contracted last year to help the company manage operations during the Chapter 11 bankruptcy process.

An examiner’s report has accused Kivisto and Wallace of keeping SemGroup’s risky futures trading strategy secret and misleading creditors.

Both Kivisto and Wallace refused to answer the examiner’s questions, but both later denied any wrongdoing. The Securities and Exchange Commission also is investigating SemGroup’s collapse.

SemGroup is a midstream service company that moves petroleum products from the wellhead to the wholesale marketplace.

The company was one of the nation’s fastest-growing until last year, when it lost at least $2.4 billion in failed short positions on the oil futures market, according to reports. It also owes another $3.5 billion to creditors, vendors and producers, records show.
