Oilfield Solid Potassium Formate

Oilfield Solid Potassium Formate Drilling & Completion Fluid Solutions — High Purity, High Performance

Oilfield Solid Potassium Formate (HCOOK, CAS No. 590-29-4) is a white crystalline organic salt engineered specifically for demanding upstream oil and gas operations. Its molecular weight is 84.12 and its solid density is 1.91 g/cm3. It provides consistent performance as a base for high-density drilling, completion and workover fluids. Shanxi Zhaoyi Chemical Co., Ltd. is a leading acetate and formate chemical producer with over 30 years of expertise and 150,000 tons of yearly capacity. This product is for B2B customers who cannot afford to have downhole failures caused by poor fluid chemistry.

Technical Specifications

Why Oilfield Solid Potassium Formate Outperforms Conventional Fluids

Stress corrosion cracking of high-value downhole alloys in traditional chloride and bromide brines is a concern. This danger is completely eliminated in potassium formate brine oilfield applications, since formate ions are non-corrosive to steel and compatible with the delicate metallurgy employed in current completions.

You get a uniform, solids-free brine that reaches the precise density required for your formation, with purity of ≥98% and chloride level closely monitored to < 0.03%. Moisture content is maintained below 1.0% to ensure the product dissolves fast and cleanly when you need it on the rig, and to minimise caking during storage and shipment.

The corrosion rate of the product to carbon steel is restricted to 0.03 g/m2.h or less, thus reducing the tube wear expenses during the life of the well.

Thermal Stability and Polymer Protection

Thermal stability is one of the greatest advantages in performance. This product is chemically stable up to 210°C (410°F) and is thus suitable for High-Pressure High-Temperature (HPHT) wells where conventional polymer based fluids often fail.

In addition to the stability of potassium formate itself, the molecule acts as an antioxidant buffer to protect common viscosifiers such as Xanthan gum and PAC against thermal breakdown. This way, your fluid system remains rheologically stable at depth, allowing for correct regulation of Equivalent Circulating Density (ECD) and minimising the risk of barite sag.

The slightly alkaline pH range (9–11) also buffers against acidic reservoir gases like CO₂ and H₂S, which helps preserve the efficacy of your whole fluid composition.

Shale Inhibition and Borehole Stability

Drilling through reactive clay and shale zones, fluid chemistry is a direct function of wellbore integrity. The potassium formate drilling fluid density may be adjusted to be close to the formation pressure and the formate ion creates a high osmotic pressure gradient which dehydrates clay platelets and inhibits swelling.

This mechanism is better than inhibition with KCl, especially in long reach drilling and in horizontal wells with a significant shale contact area.You reduce the chance of differential sticking, bit balling, and borehole collapse — all of which drive non-productive time costs.

The Oilfield Solid Potassium Formate is also compatible with enzyme breaker systems used for filter cake removal during completion, which simplifies your fluid management program.

Application Scenarios

HPHT Drill-In Fluids This product produces solids free drill-in fluids at bottom hole temperatures more than 200°C with predictable rheology and no barite sag potential.

Potassium formate completion fluid: It minimises skin factor & formation damage at pay zone as potassium formate completion fluid. It is especially useful in offshore areas where non-toxic, ecologically friendly fluids are mandated by discharge laws.

Workover and Well Intervention The high density obtainable in the absence of solids makes it appropriate for kill fluids and packer fluids where both formation contact and pressure control are crucial.

Deepwater Operations Its low crystallisation point at high density means that it remains fluid at the low temperatures of the seafloor in deepwater completions.

Oilfield Solid Potassium Formate vs Other Products

Quality Control and Documentation

Quality inspection for this product follows API and ISO standards across four key parameters.

Purity is verified by titration to confirm ≥98% KCHO₂ content, which directly determines the achievable brine density. Water insolubles are tested by gravimetric method and must remain below 0.2% to avoid pore throat plugging in reservoir formations.

Heavy metals including Lead, Arsenic, and Cadmium are tested in every production batch — a mandatory requirement for offshore environmental compliance and discharge permits in regions such as the North Sea. pH and alkalinity are also confirmed to fall within the 9–11 range.

Full documentation is available per shipment, including COA, MSDS, and third-party test reports on request.

FAQ

Q: What density can potassium formate brine achieve when using this solid product?

A: Potassium formate brine solutions for oilfield applications may be formulated at densities up to 1.57 g/cm3 (13.1 lb/gal) when dissolved at maximum concentration, which can meet the majority of HPHT and deepwater formation pressure requirements.

Q: How does the purity level impact my drilling fluid performance?

A: ≥98% purity assures the purity of your brine will dependably meet the theoretical density yield. Lower purity indicates more dissolved pollutants in your fluid system that might compromise viscosity, pH control and formation compatibility.

Q: Is this product usable as a completion fluid for offshore areas with potassium formate?

A: Yeah. It is biodegradable, has low toxicity and is in accordance with North Sea PLONOR regulations and is thus ideally suited for offshore completion activities where environmental discharge permits are necessary.

Q: How fast does the product dissolve on site?

A: The main design qualities are good solubility and quick dissolving speed. It disperses fast under normal mixing circumstances to provide a clear, solids-free brine without long agitation times.

Q: Can the product be customized in packaging or specification?

A: Yes. Shanxi Zhaoyi Chemical can provide customised package size, OEM labelling, and multi-language paperwork such as MSDS and COA. Joint development may be arranged for special purity and low impurity grades.

Q: What is the typical lead time for bulk orders?

A: Standard production lead time is approximately 5–7 working days. For in-stock quantities, delivery can be arranged within 24 hours. Technical inquiries are responded to within 2 hours.
