Aquasol makes a range of products based on polysaccharides which offer fluid loss performance and in some cases rheology improvements for water based drilling fluids.
Aquabloc: Offers fluid loss control up to 250*f in fresh water and sea water drilling mud. It is biologically stable and gives little additional high end rheology but will increase low end rheology and gels.
Aquabloc HT: Gives fluid loss control to temperatures greater than 300*f. This product performs in most water based muds and is recommended where temperatures will reach 250*f and above or where salt levels are high. Aquabloc HT will also add a little rheology.
Aquadril: Aquadril offers fluid loss control up to 275*f in most drilling mud but is made specifically to comply with Microtox regulations in Alberta, Canada.
Aquabloc AW-25: Is a liquid fluid loss additive for situations where the mixing of powders is an issue. The product is already in solution and so no hydration time is necessary.
Aquabloc 330AW: A very highly cationic starch. Will complex with clay and other reactive particles preventing agglomerations which can lead to problems.
