Latex-based fluid loss control sealant
Seals low-permeability, microfractured formations in shale gas and unconventional plays.
Recognizing that no two shale plays are alike as well as the need to rein in costs, M-I SWACO developed the HydraGlyde high-performance water-based drilling fluid system specifically for the economically challenging North American onshore unconventional sector.
The system provides a fast, trouble-free, flexible drilling fluid solution that fits within rigid AFE and HSE constraints. Its novel cost-effective chemistry reduces torque and drag in addition to shale swelling and dispersion. The HydraGlyde system delivers oil mud–comparable ROP, exceptional hole cleaning, and wellbore stability in high-angle-build and long-lateral sections—all while reducing restrictive costs and decreasing environmental impact.
The HydraCap encapsulating additive is a low-molecular-weight, dry acrylic acid copolymer that replaces the conventional partially hydrolyzed polyacrylamide (PHPA) additive to minimize clay dispersion and enhance wellbore integrity. Compared with PHPA, the HydraCap additive disperses more in water and generates less viscosity.
The HydraHib shale inhibitor is a liquid polyamine shale suppressant used in inhibitive water-base drilling fluids. The inhibitor provides a high degree of wellbore stability and flexibility with the ability to adjust its concentration.
The HydraSpeed ROP-enhancing primary lubricant can be used in all types of water-based drilling systems when drilling highly deviated, extended-reach, or horizontal welIs in onshore applications. The HydraSpeed lubricant demonstrates a coefficient of friction (COF) factor of 30.8 compared with 38.9 for a higher-cost lubricants. Its unique nonhydrocarbon chemistry provides the optimal combination of lubricity, wellbore stabilization, and filtercake enhancement.
No NPT and significant waste cost savings were experienced over the trial well section.
Fluid system maintains hole stability for 19 days, North Sea.
Optimized inhibition achieved with flexible fluid system, minimizing drilling time and risk.
While drilling an interbedded formation consisting of sandstone, siltstone, and coal, an operator experienced tight hole, excessive backreaming, and increased circulation time during tripping that caused formation instability.
Used in all types of water-based systems when drilling highly deviated, extended-reach,, or horizontal welIs.
