The Experts in Drilling Fluid Systems design

M2-PLUS* Inhibited Water-Based System

This system utilizes water-based fluids, a proprietary inhibitor, and a proprietary lubricant to create an inhibited system that can replace oil-based systems in many areas. It can be prepared using both fresh water and brines and can handle mud weights exceeding 16.0 ppg.

MAXFLO* Drill-In Fluid Systems

A proprietary package that utilizes needs-configured blends of brine-based fluids, organic fluid loss control agents, M2-SS* shale inhibitor, inorganic shale inhibitors, and viscosifiers to provide to provide wellbore stability, aid in cuttings transport, and maintain formation permeability while drilling in open hole.

Oil-Based (Diesel) Systems

Invert emulsion systems are used in a variety of formations. They consist of a brine (CaCl2 or NaCl) internal phase and a hydrocarbon (usually diesel) external phase.

Polymer-Based Systems

Numerous polymers can make up these systems. Variations depend on density, temperature, and viscosity requirements. These systems can be formulated to be calcium tolerant, temperature tolerant to 325F or higher, and brine (NaCl or CaCl2) tolerant through saturation.

Calcium Based Systems

Sources of calcium are typically either lime (Ca (OH)2) or gypsum (CaSO4). Depending on pH, calcium levels can be 2,000 mg/l or higher. These systems, lime, in particular, are very tolerant of acid gases such as carbon dioxide (C02) and hydrogen sulfide (H2S).

Potassium Enhanced Systems

Most water-based muds (WBM) can be further enhanced by the addition of the potassium ion (K++) and the sources are typically potassium hydroxide (KOH), potassium acetate (CH3CO2K), potassium sulfate (K2S04), and in limited cases, potassium chloride (KCI).

Environmental Organic (SBM) System

This is an invert emulsion system that uses synthetic oil (LAO, PAO, 10, mineral oil) as its external primary phase and uses brine (CaCl2 or NAC) as its internal phase. These oils typically have a larger molecular chain than diesel and as such are more environmentally friendly.

Lignite/Lignosulfonate (CLS) System

A WBM that relies on lignite and/or chrome lignosulfonate (CLS) to disperse the particles and control (lower) rheological values. They can handle mud weights exceeding 16.0 ppg (1.92 SG) with little difficulty.

Low Solids Non-Dispersed (LSND) System

WBM does not use powerful dispersants like lignite and/or CLS to maintain lower rheological properties. The use of sodium polyacrylate technology is commonly deployed in these systems.
