Abstract

Det er beskrevet et vannbasert borefluid med en polymerlateks som er i stand til å tilveiebringe en deformerbar lateksfilm på i det minste en del av en undergnmnsformasjon for å tilveiebringe redusert borefluidtiykkinvasjon under bruk til å bore i skiferformasjoner for hydrokarbonutvinningsoperasjoner. Et fellingsmiddel slik som et silikat eller et aluminiumskompleks (f eks. natriumaluminat) blir fortrinnsvis brukt i forbindelse med polymeren. Det vannet som er til stede, inneholder vanhgvis et salt for å danne et saltvann, ofte til metning, selv om oppfinnelsen kan praktiseres med ferskvann. Hvis et salt blir anvendt, er det ofte nyttig å anvende i tillegg et overflateaktivt middel slik som f eks. betain.There is disclosed a water-based drilling fluid having a polymer latex capable of providing a deformable latex film on at least a portion of a subsurface formation to provide reduced drilling fluid invasion during drilling in shale formations for hydrocarbon recovery operations. A precipitating agent such as a silicate or an aluminum complex (e.g., sodium aluminate) is preferably used in conjunction with the polymer. The water present usually contains a salt to form a salt water, often for saturation, although the invention can be practiced with fresh water. If a salt is used, it is often useful to use a surfactant such as e.g. betaine.
