GOODWILL AND INTANGIBLES [Abstract]
Intangible Assets Disclosure [Text Block]	GOODWILL AND INTANGIBLES We account for intangible assets with indefinite lives, including goodwill, in accordance with the applicable accounting guidance, which requires us to evaluate these assets for impairment annually, or more frequently if an indication of impairment has occurred. Based upon our most recent evaluation, we determined that goodwill is not impaired. We amortize intangible assets with a defined term on a straight-line basis over their respective useful lives. In 2010, we acquired fracture diagnostics assets for $9.0 million in cash. The acquisition was recorded in the Production Enhancement business segment and resulted in an increase of $5.6 million in goodwill and an increase of $3.2 million in intangible assets. The intangible assets will be amortized over a period of 36 to 60 months.

The entire disclosure for all or part of the information related to intangible assets.
