Abstract: Methods and apparatus combinations for making a substantially horizontal water well completion for irrigation or commercial water supply purposes includes running a substantially vertical surface string of casing, running a bend section of casing that has been preformed to provide a bend angle of about 90.degree. in a straightened-out condition down through the surface section and allowing it to assume its bend condition below the lower end of the surface section, coupling the upper end of the bend section to the lower end of the surface section, running a water production section of casing through both the surface and bend sections and outward horizontally into the aquifer, and either coupling the inner end thereof to the outer end of the bend section, or extending the production section all the way to the surface. Unique coupling mechanisms, running and retrieving tools and other devices also are disclosed.

Abstract: In accordance with an illustrative embodiment of the present invention, a steel post driving machine that is mounted on the lift mechanism of a tractor includes a mast having a tubular hammer slidably guided thereon, springs to accelerate the hammer downward, a cable to lift the hammer and lengthen the springs to store potential energy therein, and a mechanism coupled to the cable and powered by the PTO of the tractor for intermittently pulling on and then releasing the cable to cause the hammer to strike repeated impact blows on the top of the steel post. Upper and lower devices are included to maintain the mast in alignment with the post as the lift mechanism is being lowered and the post is being driven into the ground by the hammer.
