ABSTRACT:
A pumping device and an efficient method of pumping petroleum from two or more low pressure wells of close proximity. The device consists of a motor that rotates a drive sprocket in a clockwise direction and a counter clockwise direction. The sprocket has a roller chain movably connected to it. The roller chain is connected to a sucker rod in a well at one end, then runs through a series of idler sprockets and said drive sprocket, then runs through another series of idler sprockets and into another well where the other end of the said roller chain is connected to another sucker rod. The device is flexibly mounted on the casing or conductors of two or more wells. The chain that goes into each well is protected by a pump casing that is bolted to the top of each well casing or well conductor. Each pump casing runs inside of each well casing or well conductor. At the bottom of each pump casing is a spring that absorbs the energy of the sucker rods as the direction of the chain and sucker rod is reversed from a downward direction to an upward direction.
