Joe Foran and Scott King's Dallas-based Matador Resources Co. (NYSE: MTDR) has joined a dozen newly public E&P, service and midstream operators in accessing public capital. The company sold 13.3 million shares at $12 each in early February. Foran sold his Matador Petroleum Corp. in 2003 to Tom Brown Inc. for some $388 million, and co-founded this version shortly after. The company operates primarily in the Haynesville and Cotton Valley plays and, increasingly, in the Eagle Ford, making some 42.5 million cubic feet per day.

Eleven more energy companies awaited pricing at press time and two additional offerings were officially postponed. They will follow 12 oilfield IPOs of December and November that raised a combined $2.27 billion at pricing. These others were filed just in the first six weeks of 2012:

• Dave Porges' spinout of EQT Midstream Partners LP (NYSE: EQM) from EQT Corp. as a master limited partnership (MLP), owning the Equitrans system in Appalachia. Included are a 700-mile interstate pipeline and 14 gas-storage facilities.

• Glenn Darden's spinout of Fort Worth-based Quicksilver Resources Inc.'s Barnett shale-gas assets in an MLP, Quicksilver Production Partners LP (NYSE: QPP), involving some 430 billion cubic feet equivalent (Bcfe) of proved reserves making some 61.6 million equivalent a day.

• Mike Wichterich's Austin, Texas-based, Permian Basin-focused Three Rivers Operating Co. Inc. (NYSE: TROC), with 200,598 net acres over the oily Bone Spring and Wolfberry formations, making 7,961 barrels of oil equivalent (BOE) a day.

• Jon Glass' Dallas-based Cinco Resources Inc. (Nasdaq: CINC) with 222.5 Bcfe of proved reserves, 90% gas, making 30 million equivalent a day, net, from Woodford and a mostly undeveloped oily position in the Eagle Ford and Powder River Basin.

• Andrew Lane's Houston-based MRC Global Inc. (NSYE: MRC), also known as McJunkin Red Man Corp. With nearly 4,000 employees, it is the largest global industrial distributor of pipe, valves and fittings.

• BreitBurn Energy Partners LP founders Hal Washburn and Randy Breitenbach's new Pacific Coast Oil Trust (NYSE: ROYT), which will offer net-profits interests in wells in southern California, where it has 33.3 million BOE of proved reserves (98% oil) making 3,391 BOE a day.

• Quantum Energy Partners LP and the Ute tribe's Denver-based Ute Energy Upstream Holdings LLC (NYSE: UTE), which is led by former Bill Barrett Corp. president Joe Jaggers. It owns 162,695 net acres in the Uinta Basin with 35.1 million BOE proved, 88% oil, making 5,276 BOE per day.

• Tom Ward's new SandRidge Mississippian Trust II (NYSE: STR), which will own royalty interests in SandRidge Energy Inc. wells on 53,000 net Mississippi Lime acres.

IPO registrations that were filed before year-end and have not yet priced include:

• Jim Volker's new Whiting USA Trust II (NYSE: WHZ), which will own interest in some oily Whiting Petroleum Corp. wells across its onshore portfolio.

• John Crum's Houston-based Midstates Petroleum Co. Inc. (NYSE: MPO), which is to begin horizontal drilling in central Louisiana, where it has 77,100 net acres and 26.2 million BOE of proved reserves, making 9,897 BOE per day, 75% liquids.

• Stuart Page's Houston-based Glori Energy Inc. (Nasdaq: GLRI), whose proprietary biotechnology in conventional formations has made more than 26,000 barrels since May 2010 from more than 100 wells.

• Charles Moncla Jr.'s Houston-based Platinum Energy Solutions Inc. (NYSE: FRAC), which was postponed at press time due to poor stock-market interest in more pressure-pumping capacity onshore the U.S.

• Matt McCarroll's Gulf of Mexico-focused Dynamic Offshore Resources LLC, whose IPO was shelved just prior to pricing as SandRidge placed an 11th-hour bid to buy the company.

• And, Chesapeake Energy Corp.-backed Frac Tech International LLC, which filed its registration in May and remains in wait.

What will these IPOs meet upon pricing? A great deal will depend on commodity prices. Matador priced below the expected $14 to $16 range as natural gas plummeted below $3 for the 96%-gas-weighted producer. Of the 20 oilfield IPOs of the past 12 months, only nine were up at press time from their initial price.
