Shale Control Viscosifiers - Shale Inhibition Drilling Mud
This high molecular weight liquid PHPA provides viscosity development and hole cleaning capability in addition to shale encapsulation properties. DX-PAL 30 has been used successfully for over 20 years to stabilize sloughing shales in fresh, KCl and salt water based drilling fluids.
A class of water muds that use partially-hydrolyzed polyacrylamide (PHPA) as a functional additive, either to control wellbore shales or to extend bentonite clay in a low-solids mud.As a shale-control mud, PHPA is believed to seal microfractures and coat shale surfaces with a film that retards dispersion and disintegration. KCl is used as a shale inhibitor in most PHPA mud designs.
Advanced developments in shale inhibitors for oil
The high-performance water-based drilling fluid system (HPWDF) carrying polyamine as a shale inhibitor shows non-dispersion, better inhibition, anti-accretion, and lubricity. Consequently, better wellbore stability is obtained when it is applied to the various drilling fields due to the superior performance of the fluid [90] .

Partially Hydrolyzed Poluacrylamide PHPA Powder PHPA
PHPA (also partially hydrolyzed polyacrylamide or HPAM) is designed for easy mixing in drilling mud systems and to improve its dispersion to eliminate “fish eyes”, This occurs in field work when mixing either large quantities rapidly or mixing high polymer concentrations without good mixing equipment.In drilling fluids, PHPA is an anionic
Partially Hydrolyzed Polyacrylamide(PHPA polymer)used for drilling fluid. Description: Partially Hydrolyzed PolyAcrylamide-PHPA is an encapsulating polymer that is normally used in conjunction with potassium chloride to provide a high degree of shale inhibition.
Drilling Mud Chemical Partially Hydrolyzed Anion
PHPA is short for partially hydrolyzed polycarylamide powder, it's a kind of drilling mud additive. It is a co-polymer of anionic character and high molecular weight. It is a water-soluble polymer, which is primarily used as a highly efficient fluid loss reducer, viscosifier and protective colloid for shale's and cutting in fresh water, calcium
Partially Hydrolyzed PolyAcrylamide-PHPA is an encapsulating polymer that is normally used in conjunction with potassium chloride to provide a high degree of shale inhibition. The polymer is anionic, attaches itself to the positively charged edges of clay platelets, thus binding the particles together.
- Is magnafloc a polyacrylamide homopolymer?
- Magnafloc® 800HP (BASF) is nominally a polyacrylamide homopolymer, although may contain up to 1 % of anionic functionalities. Fig. 3 b shows that in contrast to anionic flocculants, applying the nonionic 800HP at a dosage of only 56 g t −1 was able to induce significant aggregation of solids within the drilling fluid.
- Can ionic polymers be used as flocculants?
- Anionic polymers used as flocculants can also carry cutting in exploration drilling. These polymers are expected to encapsulate particles, making flocculation unlikely. Centrifuging cuttings-laden fluids struggles to remove fines prior to fluid return. Anionic flocculants are ineffective, but nonionics are shown to induce aggregation.
- Do nonionic flocculants reduce aggregation of fine particles?
- However, nonionic flocculants were found to be far more effective in inducing aggregation of fine particles, which in field trials (involving dosing in advance of a decanter centrifuge) typically led to a reduction in suspended centrate solids of ∼ 50 %.
- What are magnafloc® flocculants and coagulants used for?
- BASF's Magnafloc® range of flocculants and coagulants are used extensively whenever the extraction process uses water or lixiviants to aid mineral and metal recovery. In thickeners and clarifiers, the products are designed to enhance settling rates, improve clarities and reduce underflow volumes.
