Potassium Formate Brine Solution

Potassium Formate Brine Solution | High-Density Drilling Fluid for Oil & Gas Operations

Founded in 1988, Shanxi Zhaoyi Chemical Co., Ltd. is a seasoned manufacturer specializing in oilfield chemical fluids. Boasting a 27,000 ㎡ modern production plant and an annual output of 150,000 tons, we deliver premium potassium formate brine solution tailored for complex oil and gas drilling, completion and workover scenarios. Marked with CAS 590-29-4, this clear, solids-free aqueous fluid supports a maximum density of 1.57 g/cm³ and delivers stable performance under temperatures up to 200°C. It solves common industry pain points including HPHT downhole instability, shale hydration and reservoir damage, while fully meeting strict offshore environmental discharge standards worldwide.

Key Features & Benefits

Our this product outperforms traditional chloride and bromide brines, delivering high density, low corrosion and eco-friendly advantages that perfectly match the strict requirements of modern high-end oilfield projects.

Solids-Free High-Density Drilling Performance

Capable of reaching a field density of 13.1 lb/gal with zero suspended solids, this product completely eliminates barite sagging issues prevalent in deep and ultra-deep well operations. It enables precise and stable Equivalent Circulating Density (ECD) control throughout drilling and completion processes, effectively improving downhole operation safety and stability.

Shale & Clay Inhibition

The brine carries a lot of active formate ions. Inside shale formations those ions build up a strong osmotic pressure barrier. Clay stops taking on water and stops swelling, and the wellbore sloughs far less. What comes back up is a tighter, cleaner borehole. Instability problems drop sharply next to what standard KCl-based drilling fluid systems give you.

Non-Corrosive to Downhole Equipment

Brines made from calcium chloride and potassium chloride attack metal. Ours is formate-based and does not. On high-grade alloy tools it triggers no stress corrosion cracking. Downhole pipelines see none either. Equipment stays protected over the long haul. That counts when a well runs through extended operation cycles.

Offshore Environmental Compliance

North Sea PLONOR environmental rules are met in full, so qualified offshore discharge is allowed. Waste disposal bills get smaller. So does the cost of logistics. Field operations carry on efficiently, and they stay sustainable at the same time.

Technical Specifications

How It Works

The potassium formate brine solution is produced with a professional ionic stabilization mechanism. Osmotic pressure differences do the work, holding problem shale formations in place. Once pumped downhole, formate ions move into reactive clay layers. A thick water-blocking layer builds up there. Outside water can no longer get in. The clay platelets give up their water as well, which stops the formation from caving in.

Wells downhole can be tough places. They often face high pressure and high temperature. In that kind of heat, normal polymer fluids fall apart. They quit working. This formate brine behaves another way. Its molecular structure holds. So do its flow properties. When completions sit static for a long time, density stays under control. Pressure swings do not happen. Downhole safety risks do not come up either.

The formula has no solids. That means no harmful filter cake forms on reservoir surfaces. Damage to formation permeability does not happen. In open-hole completions, the return permeability rate is over 90%. More oil and gas can then be recovered.

Core Applications

HPHT Drilling & Completion Fluids

This fluid gives a stable base to drilling systems that use no solids. It performs well in deep and ultra-deep HPHT wells. Downhole pressure stays balanced. Reservoir quality is protected.

Well Workover & Packer Fluids

Perfect for well intervention, maintenance and packer setting operations. The high-purity clear brine avoids formation damage, ensuring smooth and efficient well reconstruction work.

Reservoir Drill-In Fluids

Features minimal filtrate invasion into pay zones, preserving the natural permeability of horizontal open-hole reservoirs and laying a solid foundation for high-yield production.

Offshore Drilling Projects

Fully compliant with international marine environmental standards, it supports legal offshore discharge. It greatly reduces the high waste disposal and logistics costs of traditional chloride brines for offshore operations.

Product Performance Comparison

Compared with conventional brine products on the market, our potassium formate brine achieves the best comprehensive performance in terms of corrosion resistance, thermal stability, environmental protection and cost-effectiveness, making it the preferred solution for high-standard oilfield projects:

Potassium Formate Brine Solution Certifications & Compliance

Our production facility follows ISO 9001 quality management standards to the letter. Production and quality control systems cover the full process. Certificates for ISO, KOSHER and HALAL are all valid. Products also meet international oilfield chemical specifications and North Sea PLONOR environmental standards. Every shipment leaves with a complete set of qualification documents. Those papers back up global project bidding. Customs clearance and field quality inspection rely on them as well.

Packaging & Logistics Solutions

We offer export-grade packaging options. Tell us how big your project is and we can adjust them to match. Goods travel safe that way, and product quality holds steady no matter where they ship:

1000L IBC Tanks: They stack up and are easy to move around. That suits medium-volume onshore drilling jobs and regular batch orders.

ISO Standard Tank Containers: We supply 20ft and 40ft tank containers built to professional standards. They are made for long ocean routes and big offshore projects.

Bulk Tanker Delivery: For very large onshore drilling fields, we ship the goods straight out by road tanker in bulk. Packaging costs go down and supply moves faster.

Manufacturing Process

Our raw materials are certified, high-purity formic acid and potassium hydroxide. Every neutralization reaction takes place in a sealed reactor with temperature control. That way the reaction goes to completion and almost no impurity forms.

After the reaction ends, the solution passes through filtration in several stages. Trace impurities come out at that step. Next we dilute it with deionized water. That way we reach the exact density a customer asks for.

Each batch of Potassium Formate Brine Solution goes through a strict test round. We check density and pH. Clarity gets measured too, along with the heavy metal content. Part of that work uses gravimetric methods. For the rest, we turn to titration or spectroscopy. Only material that passes is packaged and shipped, together with an official COA test report.

FAQ

Q: What density specifications can be customized and supplied by you?

A: A1: Standard density grades run from 1.10 g/cm³ up to 1.57 g/cm³. Past that range, the density formula can be made to order. We match it to your wellbore design and to the HPHT conditions you work in.

Q: Can you use this brine with the additives that most drilling fluids contain?

A: A2: Yes. It works fine with xanthan gum. Starch and the other biopolymers in drill-in fluids do too. No bad reactions happen. Performance will not drop.

Q: What is the best way to store this product on site?

A: A3: Put it in sealed tanks. Those tanks should be used for this product alone. Keep strong acids and oxidizing agents away from it. Storage temperature has to stay between 5°C and 40°C. That range stops crystallization. It also keeps the fluid stable.

Q: When kept the right way, how long does the product last?

A: A4: Store it sealed and dry, in a shaded spot. The chemistry stays stable there. For up to 24 months, nothing changes in how it performs.

Q: Can you supply the whole set of technical and certification documents?

A: A5: Absolutely. We provide official TDS, SDS, application guides and batch COA reports to support your project review, construction and customs clearance.

Q: Do you support free sample testing?

A: A6: Yes. We provide customized small-batch samples for your laboratory testing and formula verification before bulk procurement.
