5 5/8" is a regular diameter in geothermal well drilling in Japan, Korea, Phillippine, drillers use normal direction mud fluid circulation or reverse circulation.

Reverse circulation drilling has very high rate in clearing rock chipes in hole bottom, the drilling speed is very fast in drilling pebbles, rock chips are circulated to ground directly other than breaking into very small chips.
