Drilling starch (DS) is a modified starch based filtration control agent meeting API specification 13A. It used to reduce mud filtrate in most water based fluid systems. Drilling starch (DS) is functional in fresh water as well as saturated salt environment and causes minimal increase in fluid viscosity. DS is non-damaging and can be used in both Drilling Fluid and reservoir Drill-in Fluid applications. Application of Drilling starch (DS) helps – Lower filtration rate in most water based drilling fluid systems, Improve bore-hole stability,Flocculate dispersed drill cuttings in clear water drilling.
Applications:
Maintain filtration control without detrimental viscosity increase
Effective with fast drilling non-dispersed system
Functionality:
Lower filtration rate in most water based drilling fluid system
Improve bore-hole stability
Flocculate dispersed drill cuttings in clear water drilling
