Title (EN) DOWNHOLE DRILLING COMPOSITIONS AND METHODS OF PREPARATION
(FR) COMPOSITIONS DE FORAGE DE FOND DE TROU ET PROCEDES DE PREPARATION CORRESPONDANTS
Abstract: front page image
(EN)The invention provides a method of altering the properties of a drilling fluid by adding effective amounts of crushed or whole oilseeds or mixtures of crushed whole oilseeds to a drilling fluid. The crushed or whole oilseeds or mixture of crushed or whole oilseeds are selected to impart any one of or a combination of effects including but not limited to: an increase in drilling fluid emulsion stability in oil-based or invert emulsion fluids, decreased specific gravity of the drilling fluid, seepage loss control, filtration control, oil wetting and deflocculation/dispersion, of entrained solids and/or reduced torque and drag of the drilling string.
(FR)L'invention concerne un procédé de modification des propriétés d'un fluide de forage par addition, audit fluide de forage, de quantités efficaces de graines oléagineuses, broyées ou entières, ou de mélanges de telles graines broyées ou entières. Les graines oléagineuses broyées ou entières, ou les mélanges de telles graines, sont sélectionnés afin d'impartir l'un quelconque des effets suivants, ou une combinaison de ces effets comprenant, sans caractère limitatif : augmentation de la stabilité d'émulsion du fluide de forage dans les fluides d'émulsion à base d'huile ou d'émulsion inverse, diminution de la masse spécifique du fluide de forage, contrôle de la perte par infiltration, contrôle de filtration, humidification de l'huile et défloculation/dispersion des solides entraînés et/ou couple réduit et retrait du train de tiges.
