D-Drill™ 200 is an environment & brine friendly, the multifunctional formulation used for water-based mud (WBM). It is sulfonate/clay-free and readily renders WBM upon mixing with various brines and weighting agents. Based upon proprietorially constructed nanoscale structures, D-Drill™ 200 contributes superbly in the subsequent WBM regarding filtrate control, solids suspension, microfracture blockage, and brine tolerance.

LAB TESTING & APPLICATION
Typically, D-Drill
®
200 is used in WBM at a dosage between 2.0 & 5.0 w/v%. Other ingredients can be
added to the resultant WBM to address specific concerns. It is recommended that D-Drill
®
200 be firstly
added to water with the subsequent additions of salt and weighting agent. A thorough mixing with or without
hot rolling is required to acquire maximized mud performance.
