Case Study: Eagle Ford Shale drills 22% faster with SLB's next-generation Spear PDC bit
A SLB Case Study
Next-Generation Spear Bit Drills Lateral in Eagle Ford Shale 22% Faster
SLB worked with Eagle Ford Shale, where an operator needed to drill an 8¾-in curve and lateral section of at least 4,000 ft in a difficult shale formation with maximum efficiency and toolface control in a single run. The challenge was compounded by low-power rigs, low mud weights, and poor hydraulic conditions that made cuttings evacuation and directional control difficult.
SLB recommended its next-generation 8¾-in SDi516 Spear shale-optimized steel-body PDC drill bit. The redesigned bit improved cuttings removal and directional control, drilling the 4,308-ft section at an average 79 ft/h and delivering 22% higher ROP than nearest offsets, while returning in excellent dull condition with no wear on the cutting structure.
