“…The use of polymers such as cellulose derivatives (Bentriou et al 2014;Yang et al 2007;Kok and Alikaya 2005;Leliang and Guijuan 2003;Ling et al 1999;Hughes et al 1993), biopolymers (Jun et al 2001;Xie et Lecourtier 1992;Navarrete et al 2001), and guar gum (Bentriou et al 2014;Mahto and Sharma 2004;Sharma et Mahto 2006) became indispensable in water-based drilling fluids to replace the oil-based mud for environmental considerations. Many studies were carried using different polymers in formulation of water-based drilling muds.…”

An ecologically friendly water-based drilling mud (WBM) was designed by using wood wastes (WP: wood powder) in order to substitute the organic polymers which are very expensive and often make the higher cost of the oil well drilling. This present work is dedicated on studying the rheological behavior and main rheological properties of WBM containing the wood powder at different contents and sizes by substitution of usually used polymers. The effect of wood powder on the drilling fluid filtrate was also analyzed. The drilling fluid that was developed has better rheological properties and fluid loss control which are required for a good functioning of oil well drilling. By a total substitution of polymers, the wood powder (300 µm at 850 kg/m 3) can be used as a filtrate reducer of mud because the WBM filtrate obtained exhibits a minimum and having requested values for such formation.

“…Foi aprovada pelo FDA (Food and Drug Administration) em 1969, sendo aplicada a inúmeros produtos em diferentes segmentos industriais, como alimentos, fármacos, cosméticos, químicos e petroquímicos. Essa ampla aplicação deve-se, principalmente, às suas propriedades reológicas, que permitem a formação de soluções viscosas a baixas concentrações (0,05-1,0%) [9].…”

O comportamento de fluidos de perfuração em altas temperaturas, particularmente aqueles à base de água, é imprevisível e, de fato, ainda não foi totalmente compreendido. Desta forma, otimizar a composição dos fluidos surge como um dos principais fatores para controle das suas propriedades, uma vez que as propriedades reológicas dos fluidos podem apresentar grandes diferenças à temperatura ambiente e no interior do poço. Este trabalho teve como objetivo avaliar o comportamento de fluidos argilosos aditivados com polímeros e lubrificante em elevada temperatura. Para tanto, foram feitos estudos das propriedades reológicas, de filtração e pH. Os resultados evidenciaram que os fluidos estudados apresentaram baixos valores de propriedades reológicas e altos valores de propriedades de filtração. Mostraram também que o envelhecimento térmico ocasionou um processo de degradação dos aditivos utilizados, resultando na redução do pH e na caramelização dos fluidos.

“…Additives and polymers have been used in oil well cementing to improve the properties of cement slurry. Polysaccharides and their derivatives, including hydroxyethylcellulose (HEC), carboxymethyl hydroxyethylcellulose (CMHEC), guar, hydroxypropylguar, stach, xanthan, welan gum, scleroglucan, diutan and carrageenan polymers, are being used as viscosifying agents and multifunctional additives in cement slurry (Navarrete, Seheult, & Coffey, 2001, Navarrete & Shah, 2001. Cementing mid to high temperature wells poses a challenge for these types of polymer.…”

The use of polymer in cement slurry is necessary to retain viscosity at ambient temperature and thermal thickening properties with increasing temperature. Current polymers, polysaccharides and their derivatives are extensively studied. At high temperature these polymers do not yield thickening of viscosity, but exhibit loss of slurry and gas migration. Therefore, this study presents hydroxypropylmethylcellulose (HPMC) polymer as a viscosifying agent in cement slurry. The HPMC possesses a strong thermal thickening and solid suspension ability which means low viscosity at ambient temperature and viscosity increase with respect to temperature. Thus, a series of experiments was conducted on HPMC polymer as a viscosifying agent in cement slurry. Different concentrated solutions were prepared (i.e. 1.5 to 2.5 wt%), in order to characterize their viscosity with respect to shear rate and increasing temperature up to 100°C. Then, cement slurries were prepared with HPMC as the primary viscosifier, to determine the rheological properties at high temperatures. It was observed that HPMC polymer has increased viscosity from 90°C to 100°C. The improved rheology of cement slurry, in terms of plastic viscosity and yield point at different concentrations, revealed HPMC as a capable viscosifying agent at high temperature. Moreover, increased gel strength with increasing concentration was also observed, which may cause a higher pumping rate on the surface. It was concluded that HPMC polymer acts as a viscosifying agent at high temperature. HPMC-based slurries showed high rheology (plastic viscosity and yield point) with HPMC polymer. Thus, the use of this additional additive should be considered in the design of appropriate cement slurry.
