Goodwill and Intangible Assets [Abstract]
GOODWILL AND INTANGIBLE ASSETS	NOTE 4 — GOODWILL AND INTANGIBLE ASSETS Goodwill and other intangible assets with infinite lives are not amortized, but tested for impairment annually or more frequently if circumstances indicate that impairment may exist. Intangible assets with finite useful lives are amortized either on a straight-line basis over the asset’s estimated useful life or on a basis that reflects the pattern in which the economic benefits of the intangible assets are realized. Goodwill was $267.4 million and $46.3 million at June 30, 2011 and December 31, 2010, respectively. Definite-lived intangible assets that continue to be amortized relate to our purchase of customer-related and marketing-related intangibles patents and backlogs. These intangibles have useful lives ranging from four months to twenty years. Amortization of intangible assets for the three and four months ended June, 2011 and two months ended February 28, 2011 was $4.4 million, $5.8 million and $811,000, respectively, compared to $1.2 million and $2.3 million for the three and six months ended June 30, 2010, respectively. In connection with the Merger, a $5.1 million value was assigned to the Allis-Chalmers tradename. Following the Merger, Seawell and its subsidiaries, including us, have begun operating under the name Archer. As a result, it was determined that there was no material remaining value associated with the Allis-Chalmers tradename and the results for the four months ended June 30, 2011 includes an intangible asset impairment charge of $5.1 million. At June 30, 2011, intangible assets totaled $94.9 million, net of $5.8 million of accumulated amortization. Future amortization of intangible assets at June 30, 2011 is approximately $5.9 million for the remainder of 2011 and an average of approximately $11.6 million during the years ended 2012 through 2015.
