J4 Laboratory performs all necessary testing for the stimulation and fracturing fluid designs.
J4 Oil Field’s Magnum slick fluid improves performance in fresh water and brine applications. With up to 10% Potassium or Sodium Chloride (KCl or NaCl), its friction reducer capabilities and fast hydration reduce pumping and horsepower requirements.
J4 Oilfield’s Orion fluid system is an organic borate fracturing fluid system that provides a high viscosity with a low gel conversion. This fluid system consists of a buffered and low residue guar gel complex with a bottomhole application temperature of 290°F. Lower gel loading results in polymer reduction, decrease in formation damage, and improved conductivity. Based on the job requirements, the complex polymer is broken with a combination of enzymes and oxidizers into a low viscosity that is based on temperature and time.
Titanium Fluid System is a tempertaure-activated, zirconate-crosslink base fluid. It is composed of CMHPG.
Fluid is designed for use with a zirconium crosslinker followed with a buffer to assist in controlling pH to achieve the time delay needed.
The zirconium crosslink polymer bond is sensitive to shear. High shear irreversibly degrades Titanium Fluid System. The bond between the crosslinker and the polymer cannot re-form once it is broken; crosslinking in a high-shear region is not desirable because an irreversible loss of viscosity results.
By manipulating the Titanium Fluid chemistry, the crosslinking can be delayed to avoid crosslinking in the high-shear (generally 500 to 1000 sec-1) region of the tubing, while initiating crosslinking in the lower shear (generally 10 to 200 sec-1) region of the fracture.
The waterfrac (WF) series of this fluid system is pepared by adding our CMHPG gel (refined) to fresh water containing 0% to 5% KCl or KCl substitute. Concentrations of CMHPG gel for WF are listed in table 1.

Upon addition of the CHMPG slurry to the mix water, full mechanical dispersion though adequate mixing energy is required. To facilitate hydration, stabilizing pH agent (Acetic Acid, 10 – 20% solution) should be used to lower the pH of the water to 5.0 to 6.0 pH.
To obtain maximum fluid efficiency and fluid performance, the base gel containing the CMHPG polymer and hydration buffer must be completely hydrated prior to the addition of additives and crosslinker.
Resin-coated proppant, especially curable resing-coated proppan to a zirconate crosslinked fluid can interfere with the crosslinking mechanism.
pH reduction after all the additive and proppant has been added to the system may result in loss of viscosity at its initial point of crosslink.
Oil Frac System is a gelled, oil-base fluid design for the treatment of water-sensitive formations. Kerosene, condensate and a wide variety of crude oil can be used for the Oil Frac System. The temperature range of Oil Frac System are from 90 deg F to 240 deg F. Applications outside that range may result in difficulty breaking the gel below 90 deg F and insufficient viscosity at time and temperature of 240 deg F. Oil Frac System can be batch mix or continuous mixed. The batch mixing of the fluid quickly develops and maintains a stable viscosity which aids in handling and quality control in the field. The continuous mix system eliminates the time and expense of batch mixing and the cost associated with the loss of gel left in the frac tank.
