Sulphonated Asphalt / Shale Asphalt – UNITROL
Our Sulphonated Asphalt / Shale Asphalt is known as UNITROL. This is a good-performing drilling fluid with additional information about our product is shared below:
General Descriptions
UNITROL is a kind of drilling fluid additive that has many advantages with a wide role. Its basic materials are petroleum asphalt. The appearance of brown fragile chip or powder flowability. Products containing highly soluble components and some oil-soluble ingredients have excellent anti-sloughing filtration. Applicable to all kinds of water-based drilling fluid systems. A general increase in volume is 1%-3%
Application
UNITROL performs a wide variety of functions in a drilling fluid. It acts as a high-temperature fluid loss control agent and gives thin tough filter cakes.
UNITROL reduces torque and drag, inhibits the sloughing and dispersion of shales, and aids in the emulsification of oil.
Advantage of Sulphonated Asphalt / Shale Asphalt – UNITROL
• Controlled water and oil solubility to effect the best chemical and physical performance
• Minimizes damage to productive formations
• Reacts with shale to prevent or stop sloughing and swelling
• Significantly increases lubricity; either alone or synergistically with small amounts of oils and synthetics
• Environmentally acceptable – is used on land and offshore
• Extremely temperature stable – does not have the softening point typically associated with un-reacted asphaltic additives
• Inhibits dispersion of drilled solids
• Minimal and easily distinguishable fluorescence – does not hamper well logging or core analysis
• Will not leave oil slick, sheen, or rainbow on the water at offshore locations
• No emulsifiers needed to ensure proper mixing
• Stable in Drilling Applications to 500°F
Recommended Treatment
shale stabilization and control HPHT filtrate loss in water and oil-based fluids 2 – 6 lb/bbl (5.7 – 17.1 kg/m3).
• Enhance lubricity and reduce torques and drag 1 – 3 lb/bbl (2.85 –8.6kg/m3).
• Enhance wall cake properties by 2 – 4 lb/bbl (5.7 – 11.4 kg/m3).
• Emulsify oil in water-based mud 0.5 – 2 lb/bbl (1.43 – 5.7 kg/m3).
• Prevention of differential sticking 2 – 6 lb/bbl (5.7– 17.1 kg/m3).
Mixing Requirement
Conventional hopper when chlorides do not exceed 60,000 ppm. When adding to high salinity systems, pre-wetting UNITROL Additive with fresh water by adding through a chemical barrel may give the best results. If the mixing system requires, UNIDEF A (Defoamer) may be added to prevent surface foam.
Mud Types
This Sulphonated Asphalt is mostly water-based and all oil-based and synthetic mud
UNITROL is consumed on drilled solids and on the well bore. It is advisable to add 50% more UNITROL one day following the initial treatment to ensure adequate concentration.
