Methods of using invert emulsion fluids with high internal phase concentration

摘要

In a method of gravel packing a wellbore in a subterranean formation, the wellbore comprising a cased section and an uncased section, the method may include pumping into the wellbore a gravel pack composition comprising gravel and a carrier fluid comprising an invert emulsion fluid, where the invert emulsion fluid may comprise: an oleaginous external phase; a non-oleaginous internal phase, wherein a ratio of the oleaginous external phase and non-oleaginous internal phase is less than 50:50 and an emulsifier stabilizing the oleaginous external phase and the non-oleaginous internal phase.

1. A method of gravel packing a wellbore in a subterranean formation, the wellbore comprising a cased section and an uncased section, the method comprising:
pumping into the wellbore a gravel pack composition comprising gravel and a carrier fluid comprising an invert emulsion fluid, the invert emulsion fluid comprising:
an oleaginous external phase;a non-oleaginous internal phase, wherein a ratio of the oleaginous external phase and non-oleaginous internal phase is less than 50:50 andan emulsifier stabilizing the oleaginous external phase and the non-oleaginous internal phase, wherein the emulsifier is an alkoxylated ether acid.
