Optimizing Wellbore Productivity
Discover how Aphron fluid technology involves dynamic multiple phase flow that controls whole fluid, filtrate and solids invasion into your reservoir. The co-polymers and surfactants package, or “aphrons”, in the fluid systems give the fluid some very unique properties. The ability of this fluid technology to deliver solids free invasion control is a key differentiator from perceived competitive products.

Solids Control Engineering
NOS provides clients with consistent and efficient solids control by engineering, designing, and manufacturing solids control systems that meet your every project requirement from setup and optimization to servicing and repairs.
As your first line of defense against solids contamination, NOS solids control systems are complaint with API recommended practices. Our equipment for the removal of solids contamination from drilling fluids features robust construction, high G-force linear motion, and a unique screen-clamping system, requires minimal maintenance, and comes in three- and four-panel screen frame configurations.
NOS experienced engineers bring robust solutions to every wells unique set of challenges. Collaboration between the engineers, operations team, business development team, and technical support team gives us an edge in providing timely, accurate, environmentally responsible and hazard-free drilling solutions to our clients. Our research and development acumen is kept on the cutting edge by our NOS Laboratory, which is equipped with tools for advanced drilling fluids analysis and shale reactions to drilling fluids. We provide clients with the research to produce the most accurate drilling solutions. The laboratory also serves as a venue with which to provide continual training to our engineers and keep them up to date on new drilling fluids technologies.
NOS Waste Management Solutions
NOS answers the global demand for responsible drilling with reliable Waste Management Control Solutions (WMCS). We provide our clients with a full range of WMCS equipment for solids control, cutting containment, recycling, and recovery. In addition, liquid treatments, filtration, and waste disposal are all integral parts of the NOS program.
Our skilled engineers and technical support team work closely with clients to develop the waste management strategy tailored to their needs. NOS processes follow waste management principles and hierarchy (reduce, reuse, recycle, recover, treat, and responsible disposal) as well as the rigorous assessment of environmental risk and hazards.
NOS Completion Fluids
The NOS completion fluids provide maximum production with minimal damage to reservoirs, protecting production zones with a blend of brines engineered to facilitate effective and efficient drilling in high pressures and high temperatures. These carefully formulated completion fluids minimize damage to formations and prepare wells for efficient and cost-effective production. Our team of experts designed NOS completion fluids to facilitate drilling in challenging downhole conditions without compromising safety and environmental care.
drilling fluid systems
Improve drilling efficiency, increase production levels, and minimize environmental concerns with NOS drilling fluid systems, including CL Free, AphronICS, and AirBeadsLCS. At NOS, we develop drilling fluid systems that reduce HSE impact, non-productive drilling time, and costs while maximizing wellbore stability and production as well as optimizing ROP.
cl free
chloride-free systemMeet challenging drilling targets with minimal environmental impact. The CL Free system was developed in response to onshore environmental concerns, in order to avoid chloride and high-salinity WBMs while improving solids removal efficiency.
- Improved solids removal efficiency
- Highly inhibitive
- Stable, gauged hole
- High lubricity
- High ROP
- Low salinity
- Reduced bit-balling
- Reduced dilution rates
- Reduced production consumption
- Reduced overall operating cost
- Reduced elapsed drilling time
- Consistent rheology
- Minimized environmental impact
The CL Free system is highly inhibitive, controlling hydration and swelling of reactive clays by restricting water absorption and maintaining cuttings integrity. Drilling shales rich in kaolinite with conventional potassium-based drilling fluids may destabilize the clay matrix and decrease rock strength. CL Free is designed for high chemical inhibition to prevent clays from becoming plastic and to provide geo-mechanical support.
aphronICS
invasion control systemIncrease production levels in depleted reservoirs by using AphronICS as an alternative to underbalanced drilling. This solids-free system is ideal for controlling invasion and formation damage with a design that involves dynamic, multiphase flow that controls whole fluid, filtrate, and solids invasion into the reservoir.
AirBeads
lost circulation systemControlling severe losses is a challenge for any drilling fluids system, but AirBeadsLCS is an extremely effective alternative method to air or foam drilling. The system controls losses while maintaining overbalance.
- Improved overall drilling efficiency
- Reduced circulation loss
- Improved drilling in high angle and horizontal wells
- Minimized differential sticking risk
- No size and shape dependence
- Proven alternative to UBD
- Improved cement job quality
- Minimized formation damage
- Reduced cleanup time and costs
- Reduced overall operating cost
- Minimized environmental impact
Both AphronICS and AirBeadsLCS are formed by combining air with a specialized surfactant in a viscosified fluid which, when exposed to a drop in pressure, will form aphrons-compressed micro-bubbles. The systems, in which the aphrons act as colloid particles rather than material solids, permit at-balance drilling by equalizing hydraulic pressure between the wellbore and the formation.
