Energy Transfer Partners LP (ETP) said Tuesday it has nearly completed a takeover of fellow Dallas-based partnership PennTex Midstream Partners LP.

ETP said its offer to purchase 12.36 million common units of the master limited partnership (MLP) has been accepted. The transaction brings ETP’s ownership in PennTex to more than 80%, giving it the right to purchase the remaining units. ETP plans to exercise its rights and pay $20/unit, giving it full ownership.

ETP already owned about one-third (32.4%) of North Louisiana-focused PennTex when it made an unsolicited cash offer for the remaining units in May.

PennTex has a cryogenic gas processing plant in Lincoln Parish, LA; a 35-mile rich gas gathering system accessing the Lincoln Parish plant and a plant in Minden, LA, owned by DCP Midstream Partners LP; a residue gas pipeline from the Lincoln Parish plant; a processing plant near Ruston, LA, with an associated residue gas pipeline; and a natural gas liquids pipeline connecting the processing plants to third-party pipelines.

Last fall, ETP announced a $640 million deal to acquire an interest in the assets, which serve Range Resources Corp. and other producers.

The Haynesville Shale, which straddles North Louisiana and East Texas, has seen its rig count climb as producers return to the natural gas-rich play armed with new technology. The play’s location near Gulf Coast petrochemical industry demand and liquefied natural gas export terminals also continue to make the region attractive. NGI recently published a special report on the re-emergence of the Haynesville.

ETP operates a diverse portfolio of natural gas interstate and intrastate transportation and storage assets throughout the United States, along with crude oil and NGL infrastructure, among other assets. The MLP is behind the eagerly anticipated 3.25 Bcf/d Rover Pipeline to serve the Appalachian Basin, one of the largest greenfield transmission projects under development.
