Filtration loss characteristics of aqueous waxy hull-less barley (WHB) solutions

This paper offers a comprehensive, comparative study of filtration loss properties of aqueous solutions of waxy hull-less barley (WHB). Filtration loss properties of aqueous WHB solutions were compared to hydrocolloid systems prepared by using sodium bentonite, Xanthan Gum, and cellulosic biopolymer (CMC), which are some of the most common additives used for formulating drilling fluids in the oil and gas industry. Samples were prepared at various concentrations in freshwater and saline solutions, and temperature aged at 90 °C. Low pressure-low temperature (LPLT) and high pressure-high temperature (HPHT) filtration tests, and Permeability Plugging Tests (PPT) were performed on each sample. WHB displayed excellent filtration control properties, especially in saline, high temperature environments.
