Drilling operations change along with the improvement in both drilling hardware and software developments in worldwide basis. To cope with the field specific problem or establish effi cient operation, JAPEX continuously keen to adopt new drilling technology as one of the countermeasures. In the course of doing this, JAPEX have accumulated the engineering knowledge and actual operational techniques and refl ected them further in other field operations. This paper outlines JAPEX's drilling operation in two decades and recent engineering subject of the first SBM (synthetic base mud) utilized in the domestic operation.
