Abstract: An apparatus for covering a vehicle is disclosed. The apparatus comprises a frame comprising anchors. The frame comprises a ramp and rails coupled to the ramp. The apparatus further comprises a hard cover provided in the shape of a vehicle. The hard cover comprises at least one latch. The apparatus further comprises a hydraulic system provided at the frame and coupled to the hard cover. The hydraulic system is operated using a motor. The apparatus may be operated with a cable and pulley system as well. In order to cover the vehicle, the vehicle is received at the ramp and the rails are operated to align the vehicle with the frame. Subsequently, the hydraulic system is operated to lower the hard cover to cover the vehicle. Upon lowering the hard cover, the latch is operably coupled to the anchor to lock the hard cover to the frame.

Abstract: A method of microbial enhanced oil recovery from a wellbore in an oil-bearing formation that includes injecting water into the oil-bearing formation via a tubing string in the wellbore and introducing oxygen into the oil-bearing formation for consumption by microbes in the oil-bearing formation. The oxygen introduction includes delivering the oxygen into the oil-bearing formation without having the introduced oxygen contact the walls of the tubing string and without having the introduced oxygen contact the injected water within the tubing string while the injected water is in the tubing string.
