Drilling Fluids/Additives - Right Turn Supply

Clay Force NSF is a proprietary blend of liquid clay stabilizers designed to stabilize water sensitive formations, and prevent hydration. Clay Force NSF inhibits clays by means of suppressing the hydration and swelling associated with water absorption.

The Purpose of Drilling Fluid Additives and How They Work

Downhole, PHPA bonds with the outer layers of the ground material and cuttings to help prevent fluid from absorbing and swelling, which also helps reduce it from sticking to HDD tooling. Other HDD drilling fluid additives to consider High molecular weight (HMW) polymer should be used in cobble, sand and gravel ground conditions.

PHPA |Drilling Polymer |Partially Hydrolyzed Polyacrylamide

PHPA 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, sodium brines and KCL mud systems. It is compatible with most of the drilling fluid products

Optimization Of Drilling Fluid Rheological And Fluid Loss

PHPA is a high-molecular-weight polymer that coats the wellbore with a viscous layer by encapsulating the drilled cuttings; in this manner, PHPA provides a barrier to prevent water from coming

For the Portuguese and Italian sites, the PHPA (Geomud-15) polymer fluids were run at a Marsh funnel viscosity of 40 and 48 s, respectively, without major problems, although in the writers¡¯ opinion higher viscosity could have helped to prevent the collapses at the Portuguese site near the salt flats and avoided the use of bentonite at the

PHPA Powder, Partially Hydrolysed Polyacrylamide

Acuro's PHPA powder offers stability to the borehole by forming a thin layer called filter cake that seals formation of openings, thereby reducing fluid loss. It is designed to offer optimum encapsulation of dried solids and shale stabilization. Furthermore, it is also used as a viscosifier, friction reducer, flocculant, and controls fluid loss.

Recent advances of modified polyacrylamide in drilling

Consequently, polymer modification is required in drilling nowadays. The modified polyacrylamide reviewed in this paper is a polymer aqueous solution with high molecular weight, which has a similar density as water but a much higher viscosity. Further, it is a water-soluble, easily mixed dry granular, and non-gelling agent.

The present study conducted a comprehensive investigation of partially hydrolyzed polyacrylamide (PHPA) polymer fluids, an alternative to bentonite ones, to drill into a soil-limestone mixture. The fluid flow pattern, aging behavior, and the influence of finer silty clay on polymer fluid were explored.
