World-class drilling fluid products for safe, efficient and cost-effective drilling across Iraq.
Drilling in Iraq brings tough challenges: reactive shales, lost circulation in fractured carbonate zones, high-pressure formations, sour gas and high temperatures in deep wells. Expert Chem SERV supplies drilling contractors, mud service companies and operators with a complete range of drilling fluid chemicals from world-class international manufacturers. Every product meets API specifications and is stocked locally for fast delivery to rig sites.
Weighting Materials
- API Barite (4.1 and 4.2 SG grades) for density control
- Hematite for high-density muds
- Calcium carbonate (graded sizes): acid-soluble weighting and bridging agent for reservoir drilling
Viscosifiers
- API Bentonite for water-based muds
- Xanthan gum (XC polymer) for clean, shear-thinning rheology
- Organophilic clay for oil-based and synthetic-based muds
Fluid Loss Control
- PAC (polyanionic cellulose), low- and regular-viscosity grades
- CMC (carboxymethyl cellulose)
- Modified starches for polymer and reservoir drilling fluids
- Lignite and resinated lignite for high-temperature fluid loss control
- Gilsonite and asphaltic products for shale stabilization and filtration control
Shale Inhibitors
- Potassium chloride (KCl) for inhibitive muds
- PHPA (partially hydrolyzed polyacrylamide) for shale encapsulation
- Glycols and polyamine inhibitors for highly reactive clays
Thinners and Deflocculants
- Lignosulfonates (chrome-free options available)
- Polyacrylate thinners for high-temperature stability
Lost Circulation Materials (LCM)
- Graded calcium carbonate, fibrous, flake and granular LCM (mica, cellulose fibers, nut shells)
- LCM pills for severe losses in fractured and vuggy formations
pH and Alkalinity Control
- Caustic soda (NaOH), lime, soda ash and sodium bicarbonate for pH control and treating calcium or cement contamination
Oil-Based and Synthetic-Based Mud Products
- Primary and secondary emulsifiers
- Wetting agents
- Organophilic clay and fluid loss additives for oil-based muds
- Calcium chloride (CaCl₂) for brine activity control
Specialty Additives
- Drilling lubricants to reduce torque and drag
- Defoamers
- Anti-bit balling agents and rig wash detergents
- Spotting fluids to free stuck pipe
- H₂S scavengers (for example zinc-based) for sour formations
- Corrosion inhibitors, oxygen scavengers and biocides to protect drill string and fluids
Completion and Workover Brines
- Sodium chloride (NaCl), potassium chloride (KCl) and calcium chloride (CaCl₂) brines
- High-density brines and completion fluid additives available on request
