Mechanical problems and formation fracturing, however, occur occasionally during well killing operations causing complications with conventional procedures.
Well Killing With Complications Stopping the Killing Operation
Killing operations may have to be stopped because of equipment failure or for checking static pressures at certain stages of the killing process If the killing operation is interrupted the choke must be closed immediately. The . . .
