Nanoemulsion, macroemulsions, miniemulsions, microemulsion systems with excess oil or water or both (Winsor I1 Il or III phase behavior) or single phase microemulsions (Winsor IV) improve the removal of filter cakes formed during hydrocarbon reservoir wellbore drilling with OBM. The macroemulsion, nanoemulsion, miniemulsion, microemulsion systems with excess oil or water or both or single phase microemulsion removes oil and solids from the deposited filter cake. In one non-limiting embodiment, the emulsion system (e.g. single phase microemulsion, nanoemulsion, or other emulsions) may be formed in situ (downhole) rather than produced or prepared in advance and pumped downhole. Skin damage removal from internal and external filter cake deposition can be reduced.

L'invention concerne des systèmes de nanoémulsions, macroémulsions, miniémulsions présentant un excès d'huile ou d'eau ou des deux (comportement de phase Winsor I1 Il ou III) ou de microémulsions à phase unique (Winsor IV), lesdits systèmes permettant d'améliorer l'élimination de gâteaux de filtration formés lors du forage de puits de réservoirs d'hydrocarbures avec OBM. Les systèmes de macroémulsion, nanoémulsion, miniémulsion et microémulsion présentant un excès d'huile ou d'eau ou des deux, ou de microémulsion à phase unique éliminent l'huile et les solides du gâteau de filtration déposé. Selon un mode de réalisation non limitatif, le système d'émulsion (p. ex. microémulsion à phase unique, nanoémulsion ou autres émulsions) peut être formé in situ (dans le puit) au lieu d'être produit ou préparé à l'avance et pompé dans le puit. L'élimination par détérioration de la peau d'un dépôt de gâteau de filtration interne et externe peut être réduite.
