• What does drilling starch control?

  “Drilling starch reduces fluid loss. It is pregelatinized — processed to hydrate in cold water without cooking — so its swollen particles are soft and deformable: they lodge in the pores of the filter cake and deform to seal them, cutting the filtrate.”

• Standard or temperature-stabilized grade?

  “Standard modified starch is the lowest-cost filtrate control for normal-temperature sections and short exposure times. Temperature-stabilized grades are additionally modified or cross-linked for deeper, hotter sections where standard starch degrades and the filtrate climbs mid-section.”

• How much drilling starch do I use?

  “Dosage is set by pilot test against your filtrate target in the brine you actually run — starch that performs in fresh water can behave differently in saturated salt, so test in your worst-case brine. We include the technical data sheet with dosage guidance and the temperature rating when we quote.”
