Zubair Field, Iraq

Background
The Zubair field in southern Iraq is one of the largest oil fields in the world. ENI ZFOD worked with multiple service vendors for previous drilling campaigns, yielding limited results as measured by feet drilled per day, which was 174 ft/d [53 m/d] and well below the AFE 227 ft/d [69.18 m/d]. Rig move times lagged and overall NPT added to poor efficiency ratings. Consequently, ENI ZFOD held detailed discussions with Schlumberger to establish project goals and assess the complementary capabilities of the two companies. This collaboration enabled the implementation of fit-for-purpose processes and technologies.
