Product Overview

Overview
  • NanoClear® FD: Treatment of existing vertical or horizontal wells for removal & inhibition of formation damage (paraffin, asphaltene, etc.) which provides long term wettability alteration (sustained oil production averages >40% increase lasting 180+ days while water cut drops throughout time period). Pumped down backside, soak for 8-12 hours, and restart normal production. Also used as a pre-load additive in parent wells for frac hit mitigation.

  • NanoClear® CEC: Completion enhancement chemical to maximize oil recovery from new completions. (Tailored formulas for specific reservoir conditions - size and concentration of Nano-Particles optimized for performance) Product enhances water flowback, reduces residual oil saturation, and provides wettability alteration & de-emulsification. Pumped as a set gpt along with slickwater in pad and each stage. Compatible with standard frac chemicals.

  • NanoClear® ER: Enhances oil recovery from new/existing waterfloods by decreasing residual oil saturation via wettability alteration & increasing sweep efficiency and breakthrough time by improving mobility ratio. Can be used to treat producing wells in waterflood like an FD treatment or used to treat the injector wells to apply NanoClear® along with injected water.

  • NoHIT™: Is a patent-pending frac-hit mitigation technology, it's pumped with a normal preload treatment on the parent well and produces a slow in-situ gas generation reaction over 2–5 days. It acts to temporarily pressurize the depleted rock around the parent and increase the associated rock stress.

  • MicroHOLD®: Is an engineered microparticles product, delivered via an aqueous slurry, designed to penetrate and prop complex and extended shale microfracture networks.

  • SandBond™: Produces in-situ metallic bonding oxidization reaction promoting grain-to-grain sand bonding in the near-wellbore zone. (Requires time and temperature for reaction to occur. The reaction will not occur at surface conditions, nor can it bond to itself)

Technology Innovations

NanoClear® is a nanotechnology that is a water-based dispersion of more than one type of active ingredient nanoparticles. It provides enhanced benefits by having more than one nanoparticle with opposite charges in the same dispersion. NanoClear® is not a colloidal dispersion so it provides excellent compatibility with existing frac chemicals.

Some of it's benefits are:

  • Improved fluid flow and water flowback in new completions and refracs due to the reduction of interfacial tension as well as reducing the fluid affinity to the rock.
  • Reduces interfacial tension at both the liquid-liquid interface and the liquid rock interface (unlike a surfactant which operates at the liquid-liquid interface only).
  • It can remove formation damage and residual oil more effectively, thanks to it's mechanical mechanisms deriving from the Brownian Motion of the nanoparticles.
  • Increased oil recovery and deposition inhibition can be achieved by the nanoparticles "coating” the rock surface – This wettability alteration is a long terms effect due to the nanoparticles remaining in the rock surface (unlike a surfactant).
  • Due to its multiple nanoparticles it is more effective in coating various types of rock surfaces unlike a traditional single nanoparticle aka single nanofluid.
  • It is environmental friendly – non-toxic, non-flammable, and non-hazardous – and it's not regulated for transport unlike most oil and gas chemicals which are flammable and hazardous.

NoHIT™ uses an atomized aluminum technology that creates a slow exergonic hydrogen gas-generating reaction with water when promoted with selective activators at reservoir conditions.

  • It generates gas in-situ that energizes the depleted SRV of the parent well resulting in improved parent productivity.
  • It's delivered to wellsite via standard chemical containers.
  • Pumped with preload fluid, on-the-fly, at low injection rate
  • Typical treatment/parent well: 3,000–7,000 gal 2 – 5 days prior to hydraulically fracturing the child wells

MicroHOLD® ® is an engineered aqueous slurry containing 60 wt% glass quality micro-silica delivered without any HSE issues. The median size of the particles is 20-25 microns, allowing it to access and prop microfrac networks.

  • It's precisely sized to shale microfractures.
  • It's crush strength allows it to perform under extreme closure pressures (tolerance up to 15,000 psi).
  • Delivered as a slurry, so there are no dust or silica handling considerations
  • Delivered to the wellsite via standard fluid containers
  • Injected via standard chemical pumps
  • Can be mixed on-the-fly with the pad fluid at low concentrations

** SandBond™:** produces in-situ metallic bonding oxidization reaction promoting grain-to-grain sand bonding in the near-wellbore zone. (Requires time and temperature for reaction to occur. The reaction will not occur at surface conditions, nor can it bond to itself).

  • Requires no closure stress
  • Works as low as 60 0F with no upper temperature limit
  • 100% Polymer-free
  • Maintain original conductivity and permeability
  • Frac Sand flowback control
  • Unconsolidated Sand Formation
Applications

NanoClear®

  • Enhancing production of existing wells, particularly wells with high water cut
  • Improve production of new wells (treated during completion)

NoHit®

  • Mitigate FDI induced damage to parent wells, by a preload treatment that protects the parent and encourages child fracs to move into undepleted high pressure intervals

MicroHOLD®

  • Enhance Hydraulic Fracturing Operations: It decreases treatment water leak off into micro fractures, reducing treatment pressures, screen out potential, and pump time.
  • Far Field Micro Diverter: It can be used as a far field micro diverter to improve cluster efficiency and lessen frac hits. This is done by controlling excessive fracture growth and increasing near wellbore fracture network complexity.
  • Expanded Fracture Network: MicroHold® props induced and natural micro fractures to expand the connected fracture network, leading to a decreased decline rate and increased recovery factor. ** SandBond™**
  • Requires no closure stress
  • Works as low as 60 0F with no upper temperature limit
  • 100% Polymer-free
  • Maintain original conductivity and permeability
