Is a non-solid water based mud as a Drill-in-Fluid by using different sizes of salts based on reservoir pore size to minimize formation damage. The fluid density is designed for between 1.2 and 1.44 S.G (75 and 90 PCF). This system is also designed to prevent losses during drilling in high permeable zones. This fluid can be recovered and filtered for another application. Depending upon polymers used, system withstand temperature up to 275°F.

Is non-damaging drilling fluid which is formulated by high performance water based mud with a high purity calcium carbonated in different sizes to provide optimum bridging in the reservoir. The filter cake and bridges are removable by using an acidizing procedure enabling recovery of the reservoir productivity. This system is also designed to prevent losses during drilling in high permeable zones.

Is a high performance, non-solid water based mud as a Drill-in-Fluid and completion fluid which is formulated by using different types of format components for density up to 2.3 S.G (143 PCF). It is used in drilling HPHT reservoirs to minimize formation damage and increase well productivity. This fluid can be recovered and filtered for the next application. The temperature stability of the system goes up to 375°F.​
