Optimization of Partially Hydrolyzed Polyacrylamide (HPAM) Utilized in Water-Based Mud While Drilling

Water-soluble polymers are becoming increasingly important in various applications, such as stabilizer fluids and drilling muds. These materials are used as viscosifiers and filtration control agents, flocculants, and deflocculants due to their superior properties in increasing viscosity and gelling ability in the presence of crosslinkers. In general, studying the rheological behavior of

Method to quantify viscosity effects on dispersion test improves testing of drilling-fluid polymers (Journal Article) | OSTI.GOV

A series of tests comparing partially hydrolyzed polyacrylamide (PHPA) concentration amounts has helped determine a new method for monitoring the depletion rate of the inhibitor in drilling fluids. Being able to monitor actual excess inhibitor levels helps in the evaluation of drilling fluid performance and overall mud cost.
