About the cover: An operator from Longmire Swaging LS
looks over work notes years ago when the company was hired as
a subcontractor to Layne Christensen, A Granite Company, at an
inland injection well project for the Orange County Water District in
Southern California. During test pumping it was noticed sand was
coming in from 800 to 820 feet in the 16-inch wire wrap screen,
so Longmire swaged off that 20-foot section. Longmire Swaging is
located in Lemoore, California. Photo courtesy Justin McKeever.
