Drilling Salt

Sodium chloride for water- and brine-based drilling fluids — used to build brine density, inhibit reactive shale and protect the formation, supplied graded and in bulk.

Built for the well

Salt that does real work downhole

Drilling salt is sodium chloride selected for use in drilling, completion and workover fluids. Dissolved into the mud system it raises brine density for pressure control, and it suppresses the swelling of reactive clays and shale so the borehole stays stable.

Grain size is chosen for fast, complete dissolution, and every consignment is supplied with consistent quality and full traceability so mud engineers can dose it predictably.

Why this grade

Density, inhibition, consistency

01 · Performance

Density & inhibition

Builds brine weight for pressure control and suppresses clay and shale swelling to keep the hole stable.

02 · Consistency

Defined granulometry

A controlled grain-size range dissolves quickly and completely, so brine make-up is fast and repeatable.

03 · Supply

Bulk & field logistics

Packaged and delivered at field scale, with traceable batches to support your own QA.
