Subsequent Events [Abstract]
Subsequent Events [Text Block]	Subsequent Events On July 25, 2011, we closed on the acquisition of an office and service complex in Bloomfield, New Mexico. The facility will serve as the company location for our Farmington branch (it was previously used for the same purpose under a rental agreement). The building was acquired for $775,000 utilizing funds held in escrow from the sale of our former Midland headquarters and fabrication facility. The transaction completes the terms of a like-kind exchange under Section 1031 of the Internal Revenue code providing for a deferral of taxable gain realized on the sale of the Midland facility.
