1. A natural gas pumping system, comprising:
six double-acting reciprocating compressor cylinders, each cylinder including:
a first end;
a second end;
a piston reciprocating therein;
an inlet through which natural gas is received; and
an outlet through which natural gas is discharged;
the six reciprocating compressor cylinders arranged in pairs with three reciprocating compressor cylinders on a left side adjacent to three reciprocating compressor cylinders on a right side, wherein reciprocating cycles of the pistons in the three cylinders on the left side are offset by 60 degrees one from another, the reciprocating cycles of the pistons in the three cylinders on the right side are offset by 60 degrees one from another, and the reciprocating cycles of the pistons in the three cylinders on the right side are offset from the reciprocating cycles of the pistons in the three cylinders on the left side by 30 degrees such that pressure peak pulsations propagating from the reciprocating compressor cylinders on the left side occur at or near a midpoint in time between pressure peak pulsations propagating from the reciprocating compressor cylinders on the right side.
