WBM POLYAMINE SHALE INHIBITOR,WBM POLYAMINE SHALE
SL-POLYHIB polyamine based shale inhibitor is designed for water based & polymer based drilling fluids. SL-POLYHIB equips strong absorption and strong inhibition advantages, also it could overcome high flocculation, high volume fluid loss.
Before the consideration of bio-inhibitors as potential shale inhibitors, several conventional inhibitors were used. Herein, a few conventional inhibitors are discussed. The use of clay stabilizers was long practised in the waterflooding of conventional sandstones, before being used in drilling and fracturing treatments for gas and oil shales
Water-Based Glycol Drilling Muds: Shale Inhibition Mechanisms
In effect, the glycol acts as a penetrating glue which, it is believed through hydrogen bonding effects, strengthens the shale. This mechanism contrasts with other water based mud additives (e.g. PHPA or polyamines) which form a protective or encapsulating layer on the surface of the shale. Introduction. Glycol Performance .

WO2014004193A1 - Glycol ether amines for use as clay
The hydration of clays and shale in drilling operations may be inhibited by employing an aqueous based drilling fluid comprising a shale hydration inhibition agent having the formula:(Formula I should be inserted here.) wherein R is hydrogen or an alkyl group having 1 to 12 carbons, R 1 is an alkylene group having 1 to 12 carbons, and R 2 is an alkyl group having 1 to 12 carbons.
It is a liquid polyamine, shale inhibitor used in polymer-base drilling and drill-in fluids.Shale inhibition is achieved by preventing water uptake by clays, and by providing superior cuttings integrity. The additive effectively inhibits shale or gumbo clays from hydrating and minimizes the potential for bit balling.
The Development and Application of a Novel Polyamine Water
Polyamine water-based drilling fluid has been used around the world in recent years. The authors investigated the key additive SDJA-1 as polyamine shale hydration inhibitor. Results indicate that SDJA-1 can suppress clay hydration effectively and provide a pH buffer effect.
The role of PHPA as an inhibitor therefore appears to be to form a slick surface coating that reduces dispersion of cuttings and the erosion of the wellbore wall. This process is often referred to as shale encapsulation. Xanthan Gum Xanthan gum is added to many polymer muds to give the necessary shearthinning rheology, and provide hole cleaning.

- What is a non ionic polyacrylamide?
- Polyacrylamides [8-11] are widely used as retention aids in the paper industry. Non-ionic polyacrylamides (structure I) are homopolymers produced from acrylamide with the aid of a free-radical initiator.
- Which polyamine is used as a retention aid in the paper industry?
- The polyamines employed as retention aids in the paper industry are usually polycondensation products of amines and short-chain crosslinking agents, which normally contain chlorine. The simplest represen tatives of this group of substances are the condensation products of ethyl enediamine and dichloroethane .
- What is a retention aid based on polyacrylamide?
- Nowadays, most retention aids based on polyacrylamides are supplied as solids or in the form of water-in-oil emulsions. Solid products are manufactured by polymerising the monomers in water or in the aqueous phase of a water-in-oil (W /0) emulsion of an immiscible organic solvent.
- Can polyamines be used as a retention aid?
- Products with a molar mass high enough to permit their use as retention aids are supplied commercially in the form of 20-40% solutions. Like polyethylenimines, polyamines can be combined with other water-soluble polymers to boost their effectiveness.
