Subsequent Event [Abstract]
SUBSEQUENT EVENT	12. SUBSEQUENT EVENT All of our 4,743,750 subordinated units are owned by a wholly-owned subsidiary of Exterran Holdings. As of June 30, 2011, we met the requirements under our partnership agreement for early conversion of 1,581,250 of those subordinated units into common units. Accordingly, we expect that 1,581,250 of our subordinated units will convert to common units in August 2011. Additionally, all remaining subordinated units will convert to common units following any quarter, beginning with the quarter ending September 30, 2011, during which we meet each of the tests prescribed in the partnership agreement.
