Potassium Formate 75% Brine is a concentrated clear-fluid platform for tailored drilling and completion programs where density, clarity and fluid compatibility shape the design.
A clear path to well-specific density.
Potassium formate is an aqueous formate salt solution used as a base for engineered, solids-free fluid systems. The 75% concentrate offers a starting point for a job-specific density and additive package.
Plan each blend around the pressure window, downhole temperature, formation, mix water and material compatibility. Verify the final fluid in the lab before field deployment.
Built around the operation.
The 75% concentrate can be screened for several oil and gas fluid programs. Selection and additive compatibility remain project-specific.
Reservoir drilling
A clear base fluid route for density control and a tailored low-solids drilling formulation.
Completion brines
Evaluate a filtered brine where cleanliness, pressure control and equipment compatibility matter.
Well intervention
Build a density-adjusted service fluid and screen it against formation and metal-contact conditions.
Blend preparation
Use concentrate as a feedstock for target-density blends after compatibility and precipitation checks.
Three checks before the well.
Define the target, build the blend and validate the fluid before moving to the well program.
Define the target
Set density, clarity, pressure window and minimum storage temperature.
Build the blend
Use a mass balance, then add the planned fluid additives in the correct sequence.
Validate the fluid
Measure density, pH, clarity, filtration and compatibility at the relevant temperatures.
Design by mass. Verify by measurement.
Adding water lowers potassium formate concentration. The final density is determined on the actual blend at the agreed reference temperature; it cannot be inferred from a generic linear chart.
Illustrative trend only; the curve does not represent a GEOCON density or crystallization measurement.
Calculation basis
If the approved assay confirms 75 wt% and only water is added:
- Use measured masses, rather than equal volumes, for the dilution calculation.
- Confirm the starting lot concentration from its COA.
- Measure final density and check low-temperature stability of the complete formulation.

Potassium formate brine FAQ.
Technical guidance for understanding potassium formate brine, concentration, density selection, compatibility, temperature effects and fluid-program requirements.
It is screened as a clear, high-density aqueous base fluid for drilling, completion, workover and fluid-conditioning programs. The final application depends on the well design and fluid package.
The supplied Geocon sheet specifies a minimum 75% aqueous solution. Confirm the actual lot assay on its COA.
Some programs use concentrate; others dilute or blend it to a target density. Check the approved fluid program before use.
Match the target density to the well pressure window, temperature and fluid compatibility. Measure the density of the actual blend at the specified reference temperature.
It can be considered for clear-brine completion and workover designs, subject to material compatibility, filtration, corrosion and formation-damage testing.
No. A complete drilling fluid may also require viscosifiers, filtration-control agents, lubricants, pH control and other components.
Run a compatibility and precipitation screen across the intended mixing ratio and temperature range, then verify clarity, pH and density.
Temperature can change density, viscosity and crystallization behavior. Screen the blend at both storage and operating conditions.
The intended clear-brine format is free of weighting solids. Confirm clarity, insolubles and filtration quality against the project requirement and COA.
Share target density, mix-water quality, lowest storage temperature, circulating and static temperatures, expected contaminants, metallurgy and the fluid program.
