Share-Based Compensation Arrangement by Share-Based Payment Award [Line Items]
Description of performance goal			85% with a TSR (total shareholder return) goal; and 15% with an internal NVA (“NOV Value Added”, a return on capital metric) goal. TSR performance is determined by comparing the Company’s TSR with the TSR of the members of the Philadelphia Stock Exchange’s Oil Services Sector Index (OSX) for the three-year performance period. The TSR portion of the performance share awards is subject to a vesting cap equal to 100% of Target Level if the Company’s absolute TSR is negative, regardless of relative TSR results. Conversely, if the Company’s absolute TSR is greater than 15% annualized over the three-year performance period, the payout amount shall not be less than 50% of Target Level, regardless of relative TSR results. The NVA goal is based on the Company’s improvement in NVA from the beginning of the performance period until the end of the performance period. NVA is calculated as an amount equal to the Company’s (a) gross cash earnings less (b) average gross operating assets times an amount equal to a required return on assets, with certain adjustments.
