To overcome these limitations, offshore & deepwater drilling grade attapulgite delivers consistent viscosity and gel strength in full-strength seawater. Manufactured by Petropath Fluids Limited, this API-compliant salt gel clay is designed to perform reliably in offshore, deepwater, and high-salinity drilling operations.
Why Offshore & Deepwater Drilling Grade Attapulgite Works in Seawater
Traditional bentonite depends on freshwater hydration to develop viscosity. In offshore drilling environments, seawater neutralizes this swelling mechanism, causing bentonite to collapse. Offshore & deepwater drilling grade attapulgite, however, operates through a completely different mechanism.
Its unique needle-shaped, fibrous particles form a strong three-dimensional lattice through physical entanglement rather than chemical swelling. This allows the drilling fluid to maintain stable viscosity even in salinity levels exceeding 35,000 ppm.
Because of this salt-tolerant structure, offshore engineers widely recognize this material as a salt gel clay for offshore drilling, making it indispensable for marine mud systems.
API 13A Compliance for Offshore Reliability
Petropath’s API 13A offshore attapulgite is produced at an API-approved manufacturing facility in Gujarat, India. Each batch complies with:
API Specification 13A – Section 12
ISO 13500 – Drilling Grade Attapulgite Clay
Rigorous laboratory testing ensures consistency in viscosity, moisture content, particle size distribution, pH, and residue control. This guarantees dependable performance for offshore & deepwater drilling operations worldwide.
Physical & Chemical Properties
- Appearance: Free-flowing cream/tan powder
- Particle size: 100–325 mesh (customizable)
- Bulk density: ~0.6 g/cc
- Excellent colloidal stability in seawater and brine up to 300,000 ppm
- Thermal stability up to 350°F (177°C)
These properties make deepwater drilling seawater bentonite systems more predictable and operationally efficient.
