Abstract

L'invention se rapporte à une émulsion inverse destinée au forage de puis souterrains, notamment de puits de pétrole et de gaz. Cette émulsion inverse possède une alcalinité négative et comporte une phase oléagineuse, une phase non oléagineuse et un agent émulsifiant qui stabilise l'émulsion inverse dans des conditions d'alcalinité négative. Selon la présente invention, il est possible de formuler en l'absence d'une réserve alcaline des fluides de forage qui s'avèrent adaptés au forage des puits de pétrole et de gaz.
