PRODUCT DESCRIPTION
Potassium Asphalt Sulfonate is partially water soluble and water dispersible. It acts to aid in stabilizing shale sections, controlling solids dispersion and improving wall cake characteristics. Unlike some other blending gilsonite, it is highly sulfonated by unique process which leads to partially oil soluble as well. This property gives more excellent emulsifying characteristic. It is also highly resistant to temperature.
Potassium Asphalt Sulfonate stabilizes shale formation by inhibiting disintegration of the shale both chemically and physically. It inhibits the dispersion of drilling cuttings, controls high temperature high pressure (HTHP) filtration. It reduces torque and drag, prolongs the life of the bit, improves filter cake quality and enhances well productivity. It also acts as an emulsifier of diesel oil.
In addition to providing the same unique quality as Sodium Asphalt Sulfonate, Potassium Asphalt Sulfonate contributes water-soluble potassium ions to the mud system. This is beneficiary to those areas that require the specific action of potassium to adequately minimize water-induced clay swelling.
It is a proven extensively used drilling fluid additive having many fine properties. Oil asphalt is basal raw material. It appears brown in easily breakable pieces or fluidized powder. It is density is 0.98g/cm3.It is parley water soluble partly oil soluble for every kind of drilling fluid.
APPLICATION
(1) Emulsify fresh water or sea water with oil
(2) Stabilize shale stratum
(3) Reduce rotative torque and prevent jamming
(4) Substitute of oil, including crude oil, waste engine oil and diesel oil
(5) Depress the solid expansion of drill chips
(6) Control HTHP
(7) Produce thin and tenacious mud cakes
(8) Help maintain low shearing rate under HTHP
(9) Clean and stabilize well holes that have a great deal of collapsing shales.
DOSAGE
Recommended quantity to be added: 1-4%
STORAGE
During storage and transportation see that the bag is intact as the product is water soluble. But its property is not affected even if it becomes damp.
PACKAGE
25Kg net, sealed in 3-in-1 compound paper bag with plastic lining, or according to users’ requirements.
