Equity Earnings Per Unit (Policies)	6 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share, Policy	We use the two-class method when calculating the net earnings per unit applicable to limited partners, because we have more than one participating security. At June 30, 2019, our participating securities consisted of common units, Preferred Units and TexNew Mex units. Net earnings is allocated between the partners in accordance with our partnership agreement. We base our calculation of net earnings per unit on the weighted average number of common limited partner units outstanding during the period. Diluted net earnings per unit include the effects of potentially dilutive units on our common units, which consist of unvested phantom units. Distributions less than or greater than earnings are allocated in accordance with our partnership agreement.
