New public, oily Athlon Energy’s shares have soared; gassier Jones Energy’s stock has pushed through initial softness.

Paul Rady and Glen Warren are set to price their IPO of some 30 million shares Thursday evening of their Marcellus- and Utica-focused Antero Resources Corp. The pricing is expected to be at between $38 and $42 a share, raising some $1.2 billion.

The fund-raise is toward paying bank debt and further surfacing the company’s roughly 26.1 trillion cubic feet equivalent (Tcfe) of gas, gas-liquids and oil reserves. Proved reserves are some 4.9 Tcfe, 21% proved developed and 75% natural gas. First-quarter 2013 production averaged 383 million cubic feet equivalent per day. It also owns and operates gathering pipelines and four gas-compression stations. Assets are $4.8 billion; liabilities, $3.1 billion.

Rady, who is chairman and chief executive, and Warren, president and chief financial officer, founded the Denver-based shale player in 2002 after selling their three-year-old Pennaco Energy Inc.’s gassy Rockies-focused portfolio to Marathon Oil Corp. for $500 million in cash in 2001. In 2005, they sold their then-two-year-old Antero’s Barnett-shale holdings for more than $1 billion in cash and stock to XTO Energy Inc., now a business unit of ExxonMobil Corp.

Currently, Antero holds some 317,000 net acres in the Marcellus play and some 94,000 net that are prospective for production from the Utica. “In addition, we estimate that approximately 194,000 net acres of our Marcellus-shale leasehold are prospective for the slightly shallower, upper-Devonian shale,” the company reported in its S-1.

Shares are to begin trading Friday morning on the NYSE as AR.
