Background
When drilling 22-in and 16-in hole sections in a hard formation in Kuwait, an operator wanted to reduce downhole axial vibration and increase ROP to set 20-in and 13.375-in casing. Schlumberger recommended the 12-in Shock Sub impact and deviation reduction tool on 22-in and 16-in BHAs. This solution achieved drilling objectives, reducing axial vibrations and increasing ROP by 50% as well as extending the connection life of the BHA equipment and lowering the overall drilling cost per foot.
