• Weisser, Johnson & Co., Houston, has formed GasRock Capital LLC to make direct mezzanine debt investments in oil and gas as well as midstream energy projects and companies. GasRock received commitments from financial institutions that manage investment funds exceeding $7 billion. GasRock's primary focus is project debt investments in upstream or midstream energy projects, or acquisitions of between $5 million and $50 million, or larger. "Mezzanine debt has been a preferred source of capital for domestic independents for well over the last two decades," says Frank Weisser, managing director of GasRock. "The structure doesn't have the control issues of equity, and is far less dilutive, which is why it is a very popular source of capital for development projects and acquisitions." Weisser Johnson will act as the manager of GasRock. Brittany Capital Group Inc. was advisor to GasRock. • Houston-based Seacor Holdings Inc. (NYSE: CKH) and Louisiana-based Offshore Logistics Inc.

It will provide drilling capital to domestic independents. Jefferies Capital Partners is a private-equity management firm with $1 billion under management. SouthView's chief executive is Jack W. Schanck. He was most recently co-CEO of privately held Samson Investments in Tulsa and formerly chief of the Spirit Energy 76 business of Unocal (NYSE: UCL). David L. Bole, SouthView president, was a managing director at Randall & Dewey, the financial and transaction advisory firm recently acquired by Jefferies & Co. SouthView's approach will be a bit different than that of other capital providers, explains Schanck. It intends to take only nonoperated interests in low- to moderate-risk exploitation and development drilling opportunities alongside other E&P companies as a partner. Initially it will pursue deals in the $2- to $20-million range in the Midcontinent, East Texas, Upper Texas Gulf Coast, North Louisiana and the Permian Basin. "This new company will not operate. If projects meet our criteria, we're happy to invest in them. We will help finance what I call 'small E' exploration that doesn't have to have a proved developed (PDP) component," Schanck says. "Or, if someone has bought a property that has a higher percentage of proved undeveloped assets, and they're not sure how risky they really are, we would be willing to contribute investment capital for exploitation of those PUDs, separate from their financing for the proved developed portion of the deal. We'd come in after the acquisition was made." As a separate entity, the new company is not a subsidiary or affiliate of either Jefferies or Randall & Dewey, Schanck says, "but we do have the option to access their technical and financial resources on a contract basis." • New York-based Patriot Exploration Co. Inc. has found its investment niche in E&P companies looking to do drilling deals between $2- and $10 million that want to hang on to their upside. Having recently completed deals with Petrobridge Investment Management and PPC, the firm is now looking to partner up with 10 to 15 companies that have proven track records and drilling expertise. Five-year-old Patriot is led by Jonathan Feldman as founder and principal at its New York headquarters, and senior managing director Carter Henson Jr. in Houston. Previously, Feldman invested exclusively in real estate through his wholly owned company, Millennium Properties. "We came to the energy space through a series of investments. When oil was at $12 a bbl. and gas was $1.50 I thought it was a good time to get in." Henson was senior vice president at Netherland & Sewell for 17 years. "We plan to spend $25 million by the end of the year and $50 million in 2006," says Feldman. "We're interested in $2- to $10-million deals because we think there is a big market there that is underserved. Financing for these companies is usually very expensive." Patriot provides subordinated debt and equity to projects it would be interested in drilling anyway, Feldman says. It also incorporates partnership interests into some of its deal structures. In the end, the producers Patriot works with are often able to keep 100% of the upside. "You may need $5- to $6 million to drill," Feldman says, "so we'll put it in and put a cap on our return. We get a second position against existing assets and a high teen to low-20 return with retained interest in the wellbores only. The company gets a lowered cost of capital and avoids giving up a piece of the company. We just own a piece of the wellbore." Feldman expects to average five to 10 commitments per year. Long term, he's interested in establishing an equity position in overall assets. • Petrie Parkman & Co. Inc., Houston, has named Randall E. King and Jon C. Hughes co-heads of investment banking.
