Comparison between carboxymethyl cellulose (CMC) and palm oil fuel ash (POFA) as alternatives in fluid loss agent

In drilling operation, fluid loss can be defined when high hydro static pressure compared to formation pressure that caused the mud filtrate lost to the permeable formation. Fluid loss agent are used to control the process and avoid potential reservoir damage. Drilling fluid formulation has become i...

Rheology properties in for 75°F temperature showed that POFA has good plastic viscosity within the range but not good in yield point and gel strength reading compared to CMC. For high temperature, POFA showed degradation in the rheological properties. Based on both fluid loss test in LPLT and HPHT, POFA showed recommended result for LPLT condition but it reduces in performance with higher fluid loss at HPHT condition. 2018 Thesis http://eprints.utm.my/id/eprint/85796/ http://eprints.utm.my/id/eprint/85796/1/EfaSofeaAbdMutalibMSChE2018.pdf application/pdf en public http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:131658 masters Universiti Teknologi Malaysia, Faculty of Engineering - School of Chemical & Energy Engineering Faculty of Engineering - School of Chemical & Energy Engineering
