optimization of partially hydrolyzed polyacrylamide (hpam) utilized in water-based mud while drilling

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

Experimental analysis of drilling fluid prepared by mixing iron (III) oxide nanoparticles with a KCl¨CGlycol¨CPHPA polymer-based mud used

Loss of drilling fluid commonly known as mud loss is considered as one of the critical issues during the drilling operation as it can cause severe formation damage. To minimize fluid loss, researchers introduced numerous additives but did not get the expected result. Recently, the use of nanoparticles (NPs) in drilling fluid gives a new hope to control the fluid loss. A basic KCl¨CGlycol

The use of polymer solutions for deep excavations: lessons from Far Eastern experience. Solutions of water-soluble polymers have been used to stabilise deep excavations such as pile bores and diaphragm wall trenches since the 1970s. When compared with conventional bentonite slurries, these engineered fluids are recognised as bringing a number

Field Applications of PHPA Muds | SPE Drilling & Completion - OnePetro

Summary. Mud systems with partially hydrolyzed polyacrylamide polymer (PHPA) are used worldwide and have proved effective and versatile for inhibiting troublesome shale formations. We made significant changes in the generally recommended compositions for these systems and developed a systematic approach to applying them. The most significant changes are (1) the constant maintenance of 1.0 lbm
