Proven in the field for a wide range of drilling applications
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
Key fluid system chemistry, components and performance additives
The patented Evolution system formulation comprises three central components for drilling performance integrated with a complete suite of additives to further enhance performance.
These include thermally stable (to over 400°F) synthetic viscosifiers for fresh water and brine systems as well as filtration control solutions for brines that cover the full range of temperatures and brine compositions. Newpark has developed specific Evolution formations for use in HTHP conditions.
CORE SYSTEMS COMPONENTS
Viscosifier
Eliminating clay in formulation, the rugged EvoVis® polymer viscosifer serves as an inhibitive coating agent for drilled cuttings in water-based drilling fluids. And, as a secondary function, it provides filtration control.
Performance enhancers
Perfect for unconventional wells, EvoCon® fluid conditioners are water-based stabilizers that deliver high-performance optimization of EvoVis® viscosifers, and EvoLube® DPE lubricant blends. And the EvoLube® G drilling performance enhancer is an effective lubricant blend even in HPHT conditions.
Additional performance additives
Filtration control
- EvoTrol™filtration control agent reduces fluid loss in water-based drilling fluids and provides gel strength for improved hole cleaning
Fluid stability
- NewStabil™fluid stabilizer controls alkalinity in brine systems, extending the temperature stability of drilling fluid systems containing polymers derived from natural resources.
Loss control
- A wide range of lost circulation materials are effective in both freshwater and brine formulation of the Evolution system.
NewEase 487 high-performance, low-friction lubricant
Our high-performance lubricant brings together industry-leading torque reduction, exceptional performance, and maximum convenience to your drilling operations.
Mitigate the threat of friction, shaker blinding, and product loss to retention on cuttings with NewEase 487. This high-performance, low riction lubricant has reduced torque by as much as 85% in North Dakota brine during lab testing.
Developed for water-based fluids – with a specific focus on the unique chemistry found in North Dakota brine - NewEase 487 offers several benefits over traditional lubricants.
The material flows easily at low temperatures for easy mixing, shows greatly reduced foaming and virtually no shaker blinding. NewEase 487 shows a high affinity to coat metal surfaces, resulting in extended duration of efficacy.
The main advantages of NewEase 487
- Reduces torque by an industry leading 85%
- Low-foam formulation
- Lessens cuttings retention
- Exceptionally low freeze point of -20F
- Remains active downhole for longer
- Achieve the same efficacy with less product
- Cuts transportation costs
