                                 4.7.2 Small Reciprocating Primary and Booster Compressor System
                                   Most of the compressor systems for air and gas drilling  operations are provided
                               as a separate primary compressor system unit (either with  a reciprocating compressor
                               or with a rotary compressor) and a separate booster compressor system unit (always a
                               reciprocating compressor).   These units  are usually skid  mounted  and  each  has  its
                               own prime mover.
