Southwestern Energy Company is an energy company focused on exploring and producing natural gas in the southwestern region of the United States. It generates revenue through Midstream services that market its own produced gas and gathers fees associated with the transportation of natural gas to market. 
Southwestern Energy Company is an integrated energy company located in Houston, Texas and it has natural gas and crude oil exploration and production sites in Arkansas, Oklahoma, Texas, New Mexico, and Louisiana.  Southwestern Energy Production Company and SEECO, Inc., Southwestern Energy Company's wholly-owned subsidiaries, conduct most of SWN's exploration and production activities.  Conventional drilling occurs in the Arkansas part of the Arkoma Basin, and development drilling and exploration occurs in the Oklahoma part of the Akroma Basin. 
In 2009, SWN incurred a net loss of $35.8 million on revenues of $2.15 billion. This represents a turnaround from 2008, when the copany earned $568.5 million on $2.31 billion in revenues.
Southwestern Energy Company was broken up into three segments: Exploration and Production, Midstream, and Distribution. 
Exploration and Production (74.2% of total revenue): Its exploration and production segment includes SEECO, Inc., Southwestern Energy Production Company, or SEPCO, and DeSoto Drilling Company, which are all wholly owned subsidiaries of southwestern Energy Company.  All drilling is done in the United States, with drilling being done in the Arkoma Basin, East Texas, the Permian Basin and the onshore Gulf Coast.
Midstream Services (74.7% of total revenue): The Midstream services segment creates revenue by natural gas transportation fees and by marketing its own gas production and occasionally some third party gas natural gas as well. DeSoto Gathering company, a subsidiary of Southwestern Energy Company, engages in gas gathering activities dealing mainly with the Fayetteville Shale play. Southwestern Energy Services Company(SES), Southwestern Energy Company's gas marketing subsidiary, captures downstream opportunities that come up due to marketing and transportation activity..
Since Southwestern Energy Company needs to drill underground for gas, it must abide by the Government's regulations. It costs Southwestern Energy Company to comply with the regulations, and if the regulations change, the costs of abiding by them increase.  Also, since Southwestern Energy Company is the owner and operator of natural gas and oil properties, and an owner of gas gathering and transmission systems, they have to follow several federal, state, and local regulations relating to the discharge of materials and protection of the environment.  Such regulations could make Southwestern Energy Company liable for the cost of pollution clean-up, and could even result in cessation of operation in polluted areas, which could lead to increased costs of operation.  The government also has abandonment regulations, which Southwestern Energy Company could incur in the future. 
The natural gas and oil market is very competitive, and there is plenty of competition for reserve acquisitions, exploration leases, licenses, concessions, marketing agreements, equipment and labor. SWN's competitors include:
