Abstract Polyacrylamide (PAM) has become a potential additive in drilling, but it has limitations in terms of viscosity, fluid loss, and bored pile stability concerns. Previous rheological studies have reported silica (SiO2) usage in PAM modification. However, there is insufficient rheological information such as plastic viscosity, apparent viscosity, yield point, and gel strength. Herein, this research investigates the effects of SiO2 in PAM with comprehensive rheological data.

Background Patients with advanced malignancy are often on medications for co‐morbidities, including those for primary or secondary prevention. The benefit from these medications can be limited and may result in adverse effects, interact with medications used for the malignancy or associated symptoms, increase pill burden and reduce quality of life.
