In modern deepwater exploration and High-Temperature High-Pressure (HTHP) drilling regimes, mud formulation selection determines wellbore stability. Sodium Formate 99% (HCOONa) has evolved into an essential component of solids-free completion fluids, drill-in muds, and workover operations. By replacing traditional halide brines (calcium chloride, zinc bromide), high-purity sodium formate significantly reduces reservoir damage, alleviates casing corrosion, and supports drilling across unstable shale formations.
Shandong Pulisi Chemical Co., Ltd. (Stock Code: 307785), established in 2006, provides technical-grade and customizable Sodium Formate 99% powders designed for global petroleum and gas developers. Achieving a 99% minimum purity ensures that trace heavy metals, moisture, and insolubles are minimized, preventing chemical interference with polymeric fluid additives like xanthan gum, starch, and polyanionic cellulose (PAC).
High-purity sodium formate serves as an oxygen scavenger and free-radical stabilizer, protecting biopolymers from thermal degradation at temperatures up to 180°C. This protection maintains constant rheological parameters during deep well circulation.
Unlike divalent chlorides, sodium formate brines are non-corrosive to downhole metal alloys, including duplex stainless steel and chrome-based tubing. This extends casing life and lowers overall project CAPEX.
Highly biodegradable with low toxicity, sodium formate systems meet strict offshore discharge regulations. They offer an environmentally friendly alternative to traditional synthetic mud systems in ecologically sensitive areas.
The drilling industry is moving toward complex wells with extended lateral lengths and high temperature profiles. Standard drilling chemistry often struggles under these conditions, leading to downhole fluid separation, clay hydration, and lost circulation. The roadmap for formate-based fluids targets the integration of custom-engineered sodium formate systems with nanocomposite additives.
Shandong Pulisi Chemical is leading the research in developing synergistic salt mixtures, matching Sodium Formate 99% with Potassium Formate and Calcium Formate. This formulation adjusts osmotic pressure to prevent wellbore collapse in active clay formations. By lowering water activity inside the drilling fluid to match the shale pore fluid's water activity, the chemical potential driving swelling is minimized. This provides a chemical barrier that protects the formation.
| Technical Parameter | Guaranteed Specs (Technical Grade) | Oilfield Performance Benefits |
|---|---|---|
| Purity (HCOONa) | ≥ 99.0% Min | Minimizes impurities, protecting polymer additives from thermal degradation. |
| Moisture Content | ≤ 0.5% Max | Prevents caking, ensuring rapid dissolving and stable dilution downhole. |
| NaOH Alkalinity | ≤ 0.15% Max | Maintains optimal pH buffer zones without aggressive alkaline corrosion. |
| Water Insolubles | ≤ 0.05% Max | Provides a solids-free fluid that reduces formation plugging. |
| Organic Matter | Pass / Trace | Prevents foam formation and maintains density under high pressure. |
Unconventional shale reserves and deepwater gas zones present complex technical challenges. Drillers face high drag, torque, and casing wear. Using solid-weighted muds (like barite-weighted systems) can cause solid settling (barite sag) and formation damage. High-density brines formulated with 99% Sodium Formate solve this issue by offering a solids-free solution that reaches densities up to 1.33 g/cm³ (11.1 ppg) at saturation.
From a macro perspective, utilizing custom sodium formate systems supports long-term production. The absence of suspended solids prevents pore throat plugging in pay zones, maximizing production rates once the well is completed. Additionally, because sodium formate is highly soluble in water, cleanup operations are simple, requiring minimal chemical intervention during well rehabilitation. This chemical approach reduces fluid-related NPT (Non-Productive Time) for operators, lowering total drilling costs.
Based in Zibo, Shandong Province, Shandong Pulisi Chemical Co., Ltd. (Stock Code: 307785) operates an advanced chemical facility. Utilizing automated synthesis lines, we control critical parameters from raw materials to final crystallization. By integrating carbon monoxide synthesis with high-purity sodium hydroxide under precise pressures and temperatures, we produce consistent batches of 99% pure sodium formate.
Our supply chain infrastructure is designed for timely delivery. We have established regional logistics warehouses at major domestic shipping centers, including Qingdao Port, Tianjin Port, and land border crossings like Alashankou and Khorgos. This allows us to offer flexible, door-to-door delivery for international projects across Europe, the Middle East, Southeast Asia, and Central Asia.

Foreign-Oriented Economic Enterprise
Entering international markets requires strict compliance with chemical safety and environmental regulations. Shandong Pulisi Chemical maintains compliance certifications for its entire product range, ensuring a smooth customs process. We hold ISO 9001:2015 Quality Management and German BV Certifications, alongside specialized product credentials.
For chemical registration, we support clients with K-REACH submissions and maintain European regulatory standards. Our logistics partners verify that labeling, MSDS sheets, and packaging meet international maritime dangerous goods (IMDG) and local customs guidelines.
For international buyers and drilling fluids engineers, purchasing Sodium Formate 99% requires looking closely at total cost of ownership (TCO) rather than just the initial price per metric ton. Key variables that impact final costs include feedstock prices (Formic Acid and Sodium Hydroxide), ocean freight indexes, packaging choices, and domestic logistics delays.
Shandong Pulisi Chemical provides transparent pricing structures based on spot markets and long-term supply contracts. Our customer service team handles documentation, including Bill of Lading, Certificate of Analysis (COA), Phytosanitary certificates, and customs declarations. By shipping directly from our port warehouses, we bypass secondary logistics delays, ensuring stable prices and on-time delivery.
We provide tailormade solutions, including crystalline powders, granular sodium formate, and custom liquid formulations, to meet various oilfield requirements.
Available in 25kg PP/PE bags, 1000kg jumbo bulk bags with moisture-barrier liners, and custom container options for overseas bulk transport.
