RHEO-DRILL is the original KCI / PHPA low solids, non-dispersed fluid system that is primarily used to drill moderately reactive shales.

RHEO-DRILL1 is an established inhibitive water-based fluid designed to meet difficult drilling targets with minimal environmental impact

RHEO-SHARP DRILL is a new generation High Performance Water-Based Mud (HPWBM), which provides wellbore stability, enhanced inhibition and rapid penetration rates.

RHEO-SILICATE is essentially a system which utilizes 5 – 15% v/v sodium or potassium silicate solution to enhance inhibition and mechanical wellbore stability, particularly in highly fractured or unconsolidated formations.

RHEO-NDF drill-in fluids are custom designed to provide minimal reservoir damage over a wide range of porosities and permeabilities, whilst at the same time providing an easily removable filter cake on drawdown that typically does not require breakers or acid clean-ups.

RHEO-HT PLUS systems have proven effectiveness in high temperature conditions and in the presence of contaminants, both in the field and in the laboratory.

NAFT-LITE Invert Emulsion Drilling Fluids systems have long been the preferred system of many operators for providing excellent borehole stability under extreme drilling conditions.

NAFT-COGENT is designed to provide emulsion and rheology stability beyond the temperature limits of standard NaFT-LiTE emulsion systems.
