Other Income and Expenses [Abstract]
Other Income and Other Expense Disclosure [Text Block]	11. SEVERANCE AND OTHER CHARGES In response to lower commodity pricing and reduced spending by our clients related to oil and gas producing fields in 2015, we decided during the first quarter of 2015 to reduce our cost structure, primarily through a reduction in our workforce, to better align with anticipated activity levels for 2015, which is summarized below. As a result of these cost reductions, we recorded a charge of $7.1 million in the first quarter of 2015. Depending on how the market situation evolves, further actions may be necessary, which could result in additional charges in future periods. •Reduction in Force ($6.4 million): termination benefits expensed and paid or accrued at March 31, 2015, •Facility Exit Costs ($0.5 million), and •Asset Write-Offs ($0.2 million): write-off of assets that have no associated future cash flows. During the second quarter of 2015, we continued to closely monitor rig counts, crude oil and natural gas prices, and activity levels within the industry. We continued our reduction in force initiative which began in the first quarter of 2015, but no additional accruals or write-offs were recorded during the second quarter of 2015.
