Oil Drilling

SEED’s HEC creates appropriate drilling fluid viscosity and rheological properties that suspend drill cuttings during circulation, prevent cuttings settling when circulation stops, transport cuttings to surface for removal, and maintain wellbore cleanliness throughout drilling operations. HEC provides exceptional salt tolerance, maintaining viscosity and fluid loss control in high-salinity environments including seawater-based muds, saturated salt drilling fluids, and formations with high formation water salinity.
Our PAC represents the premium cellulose derivative for demanding drilling operations in reactive shale formations, high-temperature wells, and environmentally sensitive areas requiring minimum formation damage. PAC provides exceptional shale stabilization through multiple mechanisms. The anionic polymer chains adsorb onto clay mineral surfaces, creating repulsive electrostatic forces that prevent clay swelling and dispersion.
Our CMC (Carboxymethyl Cellulose) provides cost-effective viscosity and fluid loss control in standard drilling applications where the enhanced performance of PAC isn’t required or where budget considerations favor economical solutions. CMC is particularly valuable in shallow drilling, water well drilling, and mineral exploration drilling where less demanding conditions don’t justify premium polymer costs.
