During the third quarter, Southwestern Energy Co. grew natural gas and oil production by 12% from a year ago. Costs associated with its Fayetteville Shale activities declined while well results there improved. Marcellus Shale production more than doubled from a year ago, and the company continues to find its way in the emerging Brown Dense play.

Marathon Oil Corp. is selling all of its interest in 98,409 gross acres (96,738 net) in nine tracts in Karnes, Northern Bee and Wilson counties, TX, in the Eagle Ford Shale. However, the play remains a core focus of the company.

Total U.S. marketed natural gas production remains at historically high levels but flattened during the first seven months of 2012, primarily in response to lower gas prices, the U.S. Energy Information Administration (EIA) said last week.

Midstates Petroleum Co. agreed to pay Eagle Energy Production LLC $650 million in cash and stock for all of Eagle’s producing properties, and both developed and undeveloped acreage, primarily in the Mississippian Lime oil play in Oklahoma and Kansas, the Houston-based producer said Monday.

Carrizo Oil & Gas Inc. beat its guidance and achieved record production and revenue during the second quarter of 2012, thanks in large part to new oil production from longer laterals drilled in the Eagle Ford Shale and a flatter-than-expected decline in natural gas production with new wells brought online in the Marcellus Shale.

Driven primarily by continuing record oil production from the Bakken Shale formation, North Dakota’s economy is booming and is on target to produce more than $3.5 billion in tax revenues by the end of the state’s current two-year (2011-2013) fiscal year budget period, according to the state tax commissioner.

U.S. natural gas and oil merger and acquisition (M&A) deals over the past two years primarily were driven by shale and unconventional activity, but that changed in the second quarter as midstream deals, particularly gathering and processing targets, accounted for more than half (55%) of the total deals, according to PwC US.
