Drilling Knowledge: Low pH water-based polymer mud (mud PHPA)

Low pH water-based polymer mud (low pH PHPA mud /) is one of the famous water-based mud systems because it is partially hydrolyzed polyacrylamide (PHPA) particles that function as protective colloid in the mud drilling. As you know, the water phase will act causing problems shale formation borehole drilling wells that collapse, swelling clay, cut build, etc..

phpa mud - schlumberger oilfield glossary

PHPA mud - Schlumberger Oilfield Glossary

1. n. [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.

Valorization of KCl/PHPA system of water-based drilling

The effectiveness of PHPA in water-based drilling fluid is based on good hydration and homogenization in fresh water and an improper pH control, causing hydrolysis of PHPA polymers and creating ammonium hydroxide (Liao and Siems, 1990).

Field Applications of PHPA Muds CONTROL DRILLING SOLIDS

The previously noted investigators discussed the following important design features of PHPA muds: (1) maintaining 0.5 to 1.0 lbm/bbl [1.4 to 2.9 kg/m3] PHPA in the mud, (2) keeping colloidal-solids content as low as possible with good solids-control practices, (3) controlling the pH near 8.5 to 9.0 and (4) using pre-hydrated bentonite sparingly. Pre-hydrated bentonite is used as a supplemental viscosifier in freshwater formulations but should be used sparingly in saline environments because

why ph levels are important when mixing drill mud

Why pH Levels are Important When Mixing Drill Mud

A pH of 7.0 is neutral, a pH lower than 7.0 is in the acidic range, and a pH higher than 7.0 is in the alkaline range. Drilling fluid additives were developed to be mixed with water with a pH level from 8.5 to 10 in order for the required chemical reaction to occur and to provide a proper yield.
