A METHOD OF ORIENTING A CONVENTIONALLY DRILLED CORE FOR OBTAINING DIP AND STRIKE INFORMATION COMPRISING TAKING SAID CORE BY CONVENTIONAL CORING APPARATUS, LOWERING A SIDE WALLL CORING APPARATUS IN THE BOREHOLE TO SUBSTANTIALLY THE SAME DEPTH FROM WHICH THE FIRST MENTIONED CORE WAS TAKEN, RECORDING THE AZIMUTHAL DIRECTION OF A CORE SAMPLING TUBE WITHIN SAID SIDE WALL CORING APPARATUS, PROJECTING SAID CORE SAMPLING TUBE INTO THE WALL OF THE WELL BORE TO OBTAIN A SIDE WALL CORE AND MARKING SAID SIDE WALL CORE TO INDICATE THE TOP PORTION THEREOF, WITHDRAWING SAID SIDE WALL CORING APPARATUS FROM THE BOREHOLE, REMOVING SAID CORE FROM THE SIDE WALL CORE SAMPLING TUBE, MEASURING THE DIRECTION OF MAGNETIC POLARIZATION OF EACH OF SAID CORES, ORIENTING SAID SIDE WALL CORE IN SPACE WITH REFERENCE TO SAID MARK AND THE RECORDED AZIMUTHAL DIRECTION AND ALIGINING THE CORES WITH RESPECT TO THEIR MEASURED DIRECTION OF MAGNETIC POLARIZATION, WHEREBY SAID FIRST MENTIONED CORE IS ORIENTED AS WHEN TAKEN.
