UNI CBFz

Work-over and completion Fluid

Calcium Bromide Fluids

Function:

UNI-CBF brine is used during work over and completion operations that require densities from 8.4 to 15.3 lb/gal (1007 to 1833 kg/m3).  UNI-CBF brines can be formulated with various crystallization points and are available for special applications and winter use. UNI-CBF can be used with sacked calcium chloride to obtain densities up to 15.3 lb/gal (1833 kg/m3). When used with zinc bromide brine, densities to 19.2 lb/gal (2301 kg/m3) can be achieved. Use gentle agitation when mixing for thorough dispersion.

Potassium Formate Brine

Potassium Formate (HCOOK) Brine Systems are used to formulate solid-free workover and
completion fluids.

Function:

Potassium Formate (HCOOK) Brine Systems are used for solid-free workover and completions operations which require densities have ranging from 8.4 to 13.1 lb/gal (1007 to 1570 kg/m3) and to reduce potential damage resulting from clay swelling or clay dispersion or migration. These brines eliminate the potential of formation damage due to precipitation of carbonate, bicarbonate or sulfate compounds associated with using calcium-based brines where formation waters contain high concentrations bicarbonate and sulfate ions. Potassium Formate Brine Systems can be together with sodium formate to give a more cost-effective brine system.

POTASSIUM CHLORIDE (KCl)

POTASSIUM CHLORIDE (KCl) is a soluble salt that is an extremely efficient shale stabilizer

Function:

POTASSIUM CHLORIDE (KCl) is a soluble salt that is an extremely efficient shale stabilizer when drilling hydro sensitive clays and shales. Inhibition is provided through ion exchange; the potassium ion enters between the individual clay platelets in the shale so that they are held together, thus eliminating entry of water from the drilling fluid.

Sodium Bromide Brine

Sodium bromide (NaBr) is a single salt clear brine fluid. It is available in 40  to 46 concentration

Function:

Because of its density, sodium bromide is used as a completion, work-over and packer fluid in oilfield applications.
When used with an oxidizer, such as sodium hypochlorite, sodium bromide is an excellent biocide. It has wide industrial applications, including water treatment and pulp & paper manufacturing.

 

Liquid Hydroxyl Ethyl Cellulose

Liquid viscosifier for single-salt brines

Zinc Bromide Liquid
Zinc Bromide Liquid, used for mixing high density, solids free completion brines

Function:

Used to formulate clear-brine workover and completion fluid which requires density to 19.2 lb/ gal. Inhibits hydration and migration of swelling clays.

UNIDRIL-IN

Modified Starch derivative, cross linked Non-Ionic

Function:

Non-ionic, starch derivative intended to reduce HTHP filtrate loss in all water based mud containing salts or ion sensitive additives for drilling, completion & work over application. Acts synergically with Xanthan gum polymer to increase LSRV. Can be used in most brines including seawater, NaCl, KCl, CaCl2, NaBr & formate salt systems.

UNIXAN-PLUS

Premium grade clarified Xanthan gum

Function:

Highly dispersible, premium grade, Xanthan gum used to provide superior hole cleaning and suspension, minimize filtrate invasion to formation and reduces torque and drag in reservoir drill in fluids. Provides better rheological profile with elevated low-shear-rate viscosity and highly shear-thinning characteristics

PAC-R-PREMIUM

High-quality polyanaionic cellulose Regular viscosity

Function:

Filtration control agent is used in most water-based drilling fluids, can provide secondary viscosity and is effective even at low concentrations. It is suitable for use in fresh water, salt water and brine-based fluids & stable to 300°F (149°C). Effective in moderate to high pH systems.

 

UNICOR-BRINE-20

Amine corrosion inhibitor (15-20°C ) for clear completion/ Packer brine

Function:

It controls corrosion of tubing & casing strings when used in workover & packer brines including sodium chloride, calcium chloride, sodium bromide, calcium bromide & zinc bromide. Provide protection at bottomhole temperature upto 3000F.

 

UNICOR-BRINE-30

Amine corrosion inhibitor (30-35°C) for clear completion/ Packer brines

It controls corrosion of tubing & casing strings when used in workover & packer brines including sodium chloride, calcium chloride, sodium bromide, calcium bromide & zinc bromide. Provide protection at bottomhole temperature upto 3500F.

UNICARB-F

Calcium Carbonate Flakes

 

Function:
Acid-soluble bridging and weighting agent for controlling fluid loss and density. Available in Fine, Medium & coarse grades.

UNICARB-M

Ground marble (calcium carbonate)

Function:
High purity ground marble, used as a bridging & weighting agent in drilling, work over & completion fluids. It is generally more pure with high hardness & provides better acid solubility. Available in different microns size.

 

UNILUBE-SAFE

Water soluble brine lubricant

Function:
Provides exceptional reduction in metal-to-metal friction when added to seawater, sodium chloride, sodium bromide, calcium chloride and calcium bromide completion fluids. Reduce torque and drag in high-angle, extended-reach wells.

UNICLEAN

Mud cake clean up solvent

Function:
UNICLEAN is a multi-functional surfactant additive, serves as a wetting agent, a demulsifier and an interfacial tension reducer. Soluble in oil, acid, and water to penetrate deep in the formation to dissolve oil films on fines leaving them water-wet therepreventing particle plugging and minimizing loss of permeability.
