Agitator Systems
Proven Friction Reduction, Improved Weight Transfer Agitator Systems The compression and friction forces that affect your drillstring downhole limit weight-on bit, reduce ROP, and can cause premature bit failure. With the largest fleet and the most experience, our Agitator and s have provided unparalleled friction reduction through axial oscillation. These solutions have been proven by operators around the world in nearly 50,000 runs, and we provide support at 45 global service facilities. With an in your drillstring, you can drill faster and drill farther. Agitator System The Agitator system reduces friction and improves weight transfer by gently oscillating your drillstring. It also reduces fluctuations in weight transfer to the bit. The result is enhanced toolface control, reduced stick-slip, extended reach, and improved efficiency in all modes of drilling, including rotary applications. Since the oscillations are low magnitude and only affect the longitudinal axis of your drillstring, the Agitator system does not cause the harmful lateral vibrations that can damage downhole tools. The Agitator system is compatible with all MWD systems. Proven Applications Directional drilling Wellbore intervention Fishing operations Agitator PLUS System The AgitatorPLUS system combines our Agitator oscillation tool with a special low pressure shock tool. Optimized to function as a unified system, we have configured the AgitatorPLUS system with an overall pressure drop of 300 400 psi. This allows you to maintain higher flow rates, run the AgitatorPLUS system on rigs with limited pump pressure capacity, and run two Agitator systems simultaneously in your BHA. Proven Applications Operations with limited pump capacity Extended reach drilling Tortuous well profile Benefits - Agitator and AgitatorPLUS Systems Increases sliding and rotary ROP Increases the length for extended reach drilling Reduces downhole friction and stick-slip Improves weight transfer and toolface control Prevents weight stacking and drillstring buckling Extends bit life
Unconventional Essential saved the customer $12.8k in the lateral section by increasing the sliding ROP by 22%, and total ROP by 25%. Location: Canada drilled lateral with RSS 16% faster than RSS alone and 45% faster than motor alone. Location: Alaska combined with a FluidHammer tool outperforms a previous run with RSS, increasing ROP by 222%. Location: Mexico increased ROP by 57% and up to 48% less NPT. Location: Venezuela retrieved 253 m of tubing in 45 minutes without having to jar, minimizing casing damage. Location: Norway enabled drilling twice as far and twice as fast, saving four days. Location: Africa Agitator PLUS system increased sliding ROP by 18%. Location: Russia helped mitigate stickslip to extend bit and motor life with 152% faster ROP. Location: China Vertical drilling Lateral drilling Curved drilling RSS drilling successfully drilled 7,437 ft curve and lateral with an overall ROP of 143 ft/hr. Location: Eagle Ford improved ROP by 115% in the lateral section. Location: Africa SWell drilling Fishing Hammer drilled an entire curve and lateral in one run, saving 20.5 hours. Location: Marcellus achieved equal performance as an RSS tool in horizontal drilling. Location: Argentina and Bowen super fishing jar freed a 7,348 ft RSS BHA that had been stuck for four days. Location: Saudi Arabia improved ROP by 54% and reduced vibration levels. Location: Saudi Arabia
