Drilling fluids, also known as drilling muds, are specialized fluids that enable the operator to reach the target geological position at the lowest overall cost in well construction operations. The most common drilling fluid functions are: (1) Remove cuttings from the well. (2) Control formation pressures. (3) Seal permeable formations. (4) Maintain wellbore stability. (5) Minimize reservoir damage. (6) Cool, lubricate, and support the bit and drilling assembly. (7) Transmit hydraulic energy to tools and bits. (8) Ensure adequate formation evaluation. (9) Control corrosion.

ResDrill® - High Performance Reservoir Drill-in-Fluids
-
ResDrill High-performance reservoir drill-in fluids have following characteristics (1) good formation damage control and ideally non-damaging to pay-zone in order to maximize the reservoir production (2) provide better drillability such as good hole cleaning, lubricity, shale inhibition, and wellbore stability (3) compatible with other well fluids or equipment such as completion tools, formation fluids, and completion fluids.

EcoDrill ® - Replacement of Oil Based Drill-in Fluids
-
EcoDrill systems not only provide superior clay or shale inhibition capacity, minimal fluid loss and fluid lubricity which are comparable to those of OBMs, but also bring additional benefits in cost-effectiveness and environmental protection.
