High-performance Shale Inhibitor PSH Similar to ULTRAHIB KLA-HIB
Product Description:
Amine based PSH, a new type of high-performance water-base drilling fluid shale inhibitor of my company, is a poly-amine-modified polyether polyols shale inhibitor. Amine based PSH proposes good cationic adsorbability and inhibitory
capacity and a long duration of action. It has overcome the problems which caused by cation, such as serious
flocculation, increase water loss and so on. Since the introduction of amines compounds to molecular chain,
which give it greater shale inhibition and its anticollapse mechanism is different from the ordinary polyether
products, It mainly depends on the special structure which firmly adsorbes on the clay to reduce the clay layer
spacing to prevent water from invading into the formation in order to stabilize the wall effect. The product can be
directly added to all kinds of waterbased drilling and completion fluids. The recommended treatment
concentration is usually 0.5% – 2.0%.

Advantages:
By creating a hydrophobic film on the wellbore and thus preventing water from entering into formations, it can
effectively prevent from hydration swelling, brittle shale from peeling off the wall and bit balling for its excellent
inhibiton. Especially suitable for soft mudstone formation, salt formation and water sensitive formation;
Excellent lubricant capacity, it can be applied to directional and horizontal wells;
Resistant effectively to salt, calcium and magnesium and can be applied to fresh water, brine and sea water
drilling &completion fluids;
High temperature resistance, also used in deep well and ultra-deep wells;
Non-poisonous, biodegradable and environmental friendly;
Low freezing point makes it applied to cold area;
Protect oil and gas formation;
It has a good compatibility with other additives.
