Case Study: Irkutsk Oil Company achieves 92% higher ROP with SLB's AxeBlade bit design
A SLB Case Study
AxeBlade Diamond Element Bit Design Delivers 92% Higher ROP Drills 6-in Section in One Run
Irkutsk Oil Company needed to improve penetration rates and bit durability while drilling the horizontal interval of the 6-in production section in the challenging Yaraktinskoe field in East Siberia. SLB analyzed offset well data and recommended a solution using its AxeBlade ridged diamond element bit design, along with the IDEAS integrated dynamic design and analysis platform.
SLB implemented a modified AxeBlade bit with new 13-mm Axe elements, allowing Irkutsk Oil Company to drill from shoe to TD in one run using a PDM. The result was a 92% increase in average ROP, from 9.2 m/h to 17.7 m/h, and about 40 hours of rig time saved, with the bit still in repairable condition and only minor shoulder wear.
