Oilfield & Drilling Chemical Additives
Oilfield and drilling chemicals are specialty additives used across the lifecycle of oil and gas wells — from drilling and completion through production and enhanced recovery. They fall into two broad categories: drilling fluid (mud) additives, which control the properties of the fluid circulating in the wellbore during drilling; and production chemicals, which manage flow assurance, corrosion, and separation in producing wells and surface facilities.
CheMost’s core additive chemistries — dispersants, emulsifiers, corrosion inhibitors, and EP additives — overlap significantly with oilfield chemical requirements. We supply functional components to oilfield chemical formulators and blenders who incorporate them into field-ready products. This page is the product catalog for the components we supply; scale inhibitors, H₂S / oxygen scavengers and full produced-water programs are specialist domains we describe on the Oilfield & Drilling Chemicals industry hub but do not manufacture.
Drilling Mud Additives
Rheology modifiers, fluid-loss additives, lubricants, emulsifiers, and weighting agents control drilling fluid performance in water-based (WBM) and oil-based (OBM) mud systems. Critical for wellbore stability, cuttings transport, and formation damage prevention.
Completion & Workover Fluids
Specialized fluids for well completion, stimulation (fracturing, acidizing), and workover operations. Require corrosion inhibitors, scale inhibitors, and clay stabilizers that remain effective under downhole temperature and pressure conditions.
Production Chemicals
Flow assurance chemicals (wax inhibitors, asphaltene dispersants), corrosion inhibitors, demulsifiers (for produced water separation), and scale inhibitors maintain production throughput from wellhead to refinery.

Key Additive Functions in Drilling Operations
Each drilling fluid additive category addresses a specific downhole challenge:
Lubricity Additives
Reduce torque and drag on the drill string, especially in directional and extended-reach wells. Fatty acid esters, glycol-based lubricants, and extreme pressure additives are used in both WBM and OBM systems.
Emulsifiers (OBM Systems)
Stabilize the water-in-oil emulsion in oil-based muds. Must maintain stability under high temperature and pressure and against contamination from formation brines. PIBSA derivatives and imidazoline-based products are key chemistries.
Corrosion Inhibitors
Protect drill string, casing, and surface equipment from corrosion by hydrogen sulfide, carbon dioxide, and dissolved oxygen in the drilling fluid. Film-forming amines and phosphonate inhibitors are common.
Dispersants & Deflocculants
Prevent clay platelets and drill cuttings from flocculating and gelling the mud. Polyphosphate, lignosulfonate, and polyacrylate dispersants maintain pumpable rheology. CheMost’s ashless dispersant chemistries apply directly to certain WBM formulations.
Additive Requirements: Water-Based vs Oil-Based Mud
Water-Based Mud (WBM)
- Lower cost, easier handling, preferred where environmental regulation is strict
- Requires: rheology modifiers (bentonite, CMC, xanthan), fluid-loss reducers, shale inhibitors, biocides
- Corrosion inhibition critical due to dissolved oxygen and CO₂
- Lubricity package important for directional drilling
Oil-Based Mud (OBM / SBM)
- Superior shale inhibition, thermal stability, lubricity for HPHT wells
- Requires: primary emulsifier (PIBSA-type), secondary emulsifier (S80 type), oil-wetting agents, lime for pH
- Higher performance but higher cost and more complex disposal requirements
- CheMost’s PIBSA and sorbitan ester products are applicable to OBM formulation
Treat-Rate Guidance & Documentation
Oilfield additive response is field-fluid-specific — a demulsifier is proven in your crude, a lubricity additive in your mud, an emulsifier in your OBM at downhole temperature. Use any figures as starting points and confirm in the target fluid before qualification. Emulsifier treat rates in OBM are typically PIBSA primary ~5–15 lb/bbl with an S80 co-emulsifier ~2–5 lb/bbl, adjusted to phase ratio and downhole temperature.
Every commercial shipment carries a TDS (chemical identification, physical properties, available performance data), a GHS SDS, and a per-batch COA, plus a Certificate of Origin for export. For PIBSA and reactive intermediates classified as dangerous goods, IMDG transport documentation is prepared for sea freight; EP additives carry ASTM D130 and active-sulfur data where relevant. Substance identity / CAS for import regulatory purposes is available on request.
How to Order
CheMost supplies these components factory-direct from Jinzhou to oilfield chemical formulators and blenders. Standard stocked components ship within 7–14 business days of order confirmation; minimum order is typically 200 kg (one drum), with IBC (1,000 kg) for bulk, and free 1–5 kg evaluation samples for qualified buyers. Tell us the application (OBM emulsifier package, WBM lubricity, corrosion protection, produced-water demulsification) and the fluid system, and we will confirm component availability, a starting treat rate, and supply samples to confirm in your own fluid. We do not supply scale, H₂S or full produced-water programs — those are best sourced from a specialist production-chemical house.

Frequently Asked Questions
What is the difference between drilling mud additives and production chemicals?
Drilling mud additives are used during the drilling phase to control the properties of the circulating fluid (rheology, fluid loss, lubricity, density) and protect the wellbore and equipment. They are consumed during drilling operations. Production chemicals are applied continuously or periodically once the well is producing, to manage flow assurance (preventing wax or hydrate blockages), corrosion of production tubing, scale deposition in surface equipment, and water-oil separation at the production facility. The two categories have overlapping chemistries (both use corrosion inhibitors, emulsifiers, and dispersants) but different performance requirements driven by downhole vs surface operating conditions.
How are PIBSA emulsifiers used in oil-based drilling muds?
In oil-based mud (OBM) systems, PIBSA-derived emulsifiers stabilize the water-in-oil emulsion formed by the brine phase dispersed in the base oil (mineral oil, synthetic, or diesel). The PIBSA emulsifier functions as the primary emulsifier (typically 5–15 lb/bbl), maintaining droplet size and emulsion stability under the high temperature (up to 200°C) and high pressure conditions encountered in deep wells. A co-emulsifier (often sorbitan monooleate / S80) is frequently used alongside PIBSA at 2–5 lb/bbl to improve stability and oil-wetting of drill solids. CheMost’s PIBSA and S80 products from the mining chemicals line are directly applicable to OBM applications.
What corrosion challenges are specific to oil and gas operations?
Oilfield corrosion is driven by several co-existing factors rarely encountered in other industries: H₂S (sour service) causes sulfide stress cracking (SSC) in high-strength steels and requires film-forming amine inhibitors plus material selection per NACE MR0175; CO₂ dissolves in produced water to form carbonic acid, causing mesa corrosion of carbon steel; microbiologically influenced corrosion (MIC) from sulfate-reducing bacteria (SRB) produces H₂S biogenically in sour systems; and galvanic corrosion at dissimilar metal joints (e.g., tubing to wellhead) must be managed with insulating flanges and coatings in addition to chemical inhibition.
Can lubricant additive components be used in drilling fluids?
There is significant chemistry overlap. CheMost’s ashless dispersants (PIBSA-TEPA based) are used in OBM formulations as secondary emulsifiers and oil-wetting agents, not just in lubricant applications. Extreme pressure (EP) additives (sulfurized compounds) function as drill string lubricants in WBM systems. Corrosion inhibitors from the lubricant line can be adapted for corrosion protection in water-based muds. However, the specific treat rates, compatibility testing, and regulatory requirements for oilfield applications differ from lubricant use — always verify performance in the target fluid system before qualification.
Do you supply scale inhibitors, H₂S scavengers or a full production-chemical program?
No. CheMost supplies the oilfield chemistry that overlaps its lubricant and emulsifier range — EP / lubricity, corrosion inhibitors, demulsifiers, rust inhibitors, and PIBSA / S80 emulsifiers for OBM. Scale inhibitors, H₂S and oxygen scavengers, biocides and the full continuous-injection production program are formation-specific products selected from a water-chemistry analysis by a specialist production-chemical service company. We describe them as background on the industry hub but focus on what we manufacture, document and supply — and we say so clearly rather than overstate our scope.
What are the minimum order quantities, packaging and lead times?
Minimum order is typically 200 kg (one drum) for most liquid components, with IBC (1,000 kg) for bulk. Standard stocked components ship within 7–14 business days of order confirmation; specialty grades with lower production frequency may require longer lead times, confirmed during quotation. Free 1–5 kg evaluation samples are available for qualified buyers. Contact us with the product, quantity and destination port for a specific confirmation; documentation (TDS, SDS, COA, Certificate of Origin, and IMDG/IATA where applicable) ships with every order.
What documentation and export support do you provide?
Every shipment carries a TDS, a GHS SDS and a per-batch COA, plus a Certificate of Origin for customs. For PIBSA and reactive intermediates classified as dangerous goods, IMDG (sea) documentation is prepared; EP additives carry ASTM D130 (copper corrosion) and active-sulfur data in the TDS where relevant. Substance identity and CAS information for import regulatory purposes can be requested during evaluation. We do not issue ISO 9001 certificates or CICS registration documents.
