the accompanying drawings fig1 is a view illustrating a resettable circulation tool 100 in an abrasive jet drilling assembly 200 generally the abrasive jet drilling assembly 200 is used to form a wellbore by ejecting a high velocity stream of drilling fluid which includes abrasive particles the abrasive jet drilling assembly 200 includes a jetting drill device 205 for ejecting the high velocity stream of drilling fluid the abrasive jet drilling assembly 200 is connected to a drill string not shown the abrasive jet drilling assembly 200 further includes the resettable circulation tool 100 the resettable circulation tool 100 includes a plurality of circulation ports 105 that may be selectively opened during the drilling operation to circulate drilling fluid out of the drill string and then closed the resettable circulation tool 100 could be operated multiple times during the drilling operation the resettable circulation tool 100 is normally closed and may optionally be provided with a shear pin safety system to prevent unwanted operation the resettable circulation tool 100 is movable between a closed position normal operation and an opened position in the opened position fluid is circulated out from the resettable circulation tool 100 above the device 205 to eliminate a shot column to move the resettable circulation tool 100 to the opened position from the closed position a downward motion will allow the resettable circulation tool 100 to open and allow circulation and remain in this position until.
