PHPA mud - Schlumberger Oilfield Glossary
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.
analytical method for the determination of the PHPA polymer content of drilling mud and other water-base fluids has been evident for some time. PHPA is a short-chain polymer which is special from other type of polymer that is used in the mud system either to control wellbore shales or to extend bentonite clay in a low-solids mud.
China PHPA for Brine Based Oil Drilling - China PHPA
PHPA for brine drilling Partially Hydraulised 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. It can inhibit cuttings dispersion to

Field Applications of PHPA Muds CONTROL DRILLING SOLIDS
An alternative would be to meter the amount of water added to the mud system. Material balance, a tool for the mud engineer, only indicates the concentration of product added, not the concentration of products in the system. PHPA is depleted in the mud by coating on the wellbore and on the solids ejected by the solids-control equipment.
Water-based drilling fluids are cost effective and environment friendly compared to oil-based muds. However, these muds create wellbore instability problems in water-sensitive and highly reactive shale formations (O’Brien and Chenevert 1973).Over 75% of the formations drilled for petroleum exploration and production are comprised of shale and it causes about 70% of the wellbore instability
Shale inhibitive properties of polyether diamine in water
This fluid has been considered to be a significant progress in closing the gap between water-based drilling fluid and oil-based drilling fluid. Polyether diamine, usually used as curing agent ( Kornmann et al., 2001 , Cai et al., 2008 ), has been applied for a new shale inhibitor increasingly in drilling operations.
