Evolution: Next-Gen Water-Based Technology
Engineered to meet the demands of unconventional drilling
The Evolution® high-performance water-based drilling fluid system (HPWBM) specifically meets the demands of operators when drilling challenging and unconventional formations, reducing costs and improving the environmental profile of their operations compared to OBM.
Key features and advantages:
- Matches or exceeds the ROP, wellbore management, days on well, logging and casing operations performance of OBM
- Withstands demanding operational conditions such as HPHT
- Improves wellsite cuttings and waste management options
- Minimize fluids transportation costs and impacts
- Promotes recycling and re-use of fluid
- Improves HSE factors and lowers environmental liability
Key applications: Unconventional and conventional drilling application
Fluid type: Water-based drilling fluid systems
Temperature rating (max): 425°F (220°C)
Key performance characteristics: Extreme HPHT tolerance and OBM-like lubricity.
Performance rating: Excellent. HPHT and ROP performance.
Sustainability rating: Excellent
Although developed for unconventional applications, the drilling performance and fluid stability of the Evolution system has made it highly popular with use by over 300 operators in more than 4,500 wells worldwide.
Evolution is proven not only in unconventional resource plays. It has been used successfully in conventional environments too, including high-pressure, high-temperature conditions, and other applications such as:
- Brines in the Bakken Shale
- Potassium formate in Southern Italy.
- Bottom hole conditions of over 400°F (204°C) in the Cooper Basin of Australia
- Shallow formations in Northwest New Mexico
- Densities from 8.6 lb/gal (1.03 SG) in the Spraberry of the Permian to 18.8 lb/gal (2.25 SG) in Sichuan Province, China
- C0₂ rich environments and managed contaminates
- Proven high stability in prolonged trips and casing runs
