Drilling Fluids Additives

• Shale control • Fluid loss improvement • Torque and drag reduction • Inhibition of swelling clays in all water based muds• Shale stabilizing by controlling HTHP fluid loss

• Inhibit hydratable, swelling shales.• Control filtration rates with minimal increase in rheology.• Temperature stable up to 300°F.• No fermenting and no biocide needed.• Suitable for all water-based mud from fresh water to saturated

• Reacts with shale to prevent or stop sloughing and swelling;• Effect reduce high temperature and high pressure filtration loss( HTHP FL);• Significantly increases lubricity; either alone or synergistically with small amounts of oils,

• Improve thermal stability and emulsion stability . • Prevent sloughing and stabilize shales. • Compatible with all oil based mud and synthetic based mud. • Wide range of applications with BHST from 248°F/120°C to 446°F/230°C. • Function

Amine-treated Lignite is the shale inhibitor used in Clay-rich reactive shale formation.

ME-SEAL ( Macromolecule Elastic Particles Loss Circulation agent) is Polymer elastic particles plugging agent.

ME-ASPHASOL , Sulphonated Asphalt is an acid soluble and water soluble. High purity Sulphonated asphalt product is made by solvent full sulfonation.

Emulsifier for oil-based mud, ME-EMULS is made of fatty organic acid and organic amines mix and has an amide reaction.

Thinner and Deflocculants for OBM is composed of organic ammonium and concentrated special functional agents.

Fluid-loss Agent In Mid Temperature is a modified asphalt and resin compound. Used in temperature-stable invert-emulsion OBM drilling mud. It reduces both API and HPHT fluid loss in all oil-based muds.

Asphalt fluid loss control agent, ME-TROL HT400 is a kind of oil-based mud modified Gilsonite. It can inhibit the dispersion of drilling cuttings and control HTHP filtration.

Fluid-loss Additive In High Temperature, is an Asphalt fluid loss Control Agent for HTHP drilling fluids, resistant to extremely high temperature.
