The operator wanted to maximize ROP in the horizontal section of a well after drilling through hard layers with low ROP offshore the northern Caspian Sea.
Conventional bits recently drilled the section with an average ROP of 45 m/h.
AxeBlade bits have high impact durability, achieving deeper penetration and higher instantaneous ROP than conventional bits. The diamond table on the element ridge is 70% thicker than that of a conventional cutter, increasing frontal impact resistance. PowerDrive Xceed RSS provides strength and agility in challenging environments.
In the first well, the combination achieved an ROP of 63.7 m/h. For the second well, the operator wanted to achieve a higher ROP. In this well, the operator drilled out the float collar of casing, completed a formation integrity test, and drilled 1,895 m in one run totaling 23.2 h. The combination drilled 870 m at an ROP of 81.7 m/h, achieving a real ROP 145% higher than the planned ROP. The bit had low wear, and the run set a record for fastest horizontal section in the field with the largest number of meters drilled per day.
