Title
(EN) WELL DRILLING AND PRODUCTION FLUIDS EMPLOYING PARENCHYMAL CELL CELLULOSE
(FR) FORAGE DE PUITS ET FLUIDES DE PRODUCTION UTILISANT DE LA CELLULOSE DE CELLULES PARENCHYMALES
Abstract
(EN)
Circulating and non-circulating well-drilling fluids comprising parenchymal cell cellulose. In accordance with a preferred embodiment, improved viscosity and fluid loss control in circulating well-drilling fluids are obtained from the inclusion of parenchymal cell cellulose in such fluids. In accordance with another preferred embodiment, certain polymers, especially anionic polymers, and polymers derived from hemicellulosic materials are admixed with parenchymal cell cellulose in well fluids to provide synergistic fluid loss control and other beneficial properties. Methods for the employment of circulating and non-circulating well fluids employing parenchymal cell cellulose are also disclosed.

Fluides circulants et non circulants de forage de puits comprenant de la cellulose de cellules parenchymales. Selon un mode préféré de réalisation il est possible d'obtenir une viscosité améliorée et un meilleur contrôle de la perte de fluide dans les fluides circulants de forage de puits grâce à l'inclusion dans ces fluides de cellulose de cellules parenchymales. Selon un autre mode préféré de réalisation, certains polymères, notamment des polymères anioniques, et les polymères dérivés des matériaux hémicellulosiques sont mélangés à de la cellulose de cellules parenchymales dans les fluides de puits afin d'obtenir un contrôle synergique de la perte de fluide et d'autres propriétés bénéfiques. On décrit également des procédés d'utilisation de fluides de puits circulants et non circulants utilisant de la cellulose de cellules parenchymales.
