Severance and Other Charges [Abstract]  
Severance and Other Charges [Text Block]
In 2017, as part of the efforts to streamline its business, the Company recorded $1.1 million of severance compensation and other charges.

In 2015, in response to lower commodity pricing for crude oil and reduced spending by our clients on their oil and gas fields, we reduced our cost structure, primarily through a reduction in our workforce, to better align with the decreasing activity levels into the foreseeable future. As a result of these cost reductions, we recorded severance charges of $8.8 million and a charge to income associated with the impairment of certain equipment and intangible assets and facility exit costs of $5.5 million. Also during 2015, we recorded loss contingencies for various ongoing legal issues of $8.6 million. See Note 11 - Commitments and Contingencies.
