Fluid loss control system |
| abstract |
A composition capable of imparting fluid loss control properties to aqueous systems. The composition is an admixture of: (a) a solid particulate material having a particle size distribution wherein at least about 90% of said material is capable of passing through a No. 20 U.S. Standard (Fine Series) Sieve; and (b) a cross-linked hydroxyalkyl cellulose; wherein the amount of component (a) to component (b) is in the weight ratio of at least about 0.5. The invention is further directed to improved drilling fluids containing said composition and to the process of drilling bore holes using said improved fluid. |
