ABSTRACT:
A method of drilling a well by utilizing AE/MA measurement which has the steps of monitoring an AE wave emitted at the periphery of the well, and drilling the well without lost circulation by providing lost circulation preventing means in the well if the energy of the AE wave emitted at the periphery of the well increases. Thus, the method can confirm a lost circulation layer, i.e., the size, the place and the direction of the underground crack to further determine whether further drilling is necessary or not.
