Abstract:
A method for sampling fluid in a subterranean formation includes reducing a viscosity of the fluid, pressurizing a portion of the subterranean formation, and collecting a fluid sample. Specifically, a viscosity of the fluid in a portion of the subterranean formation is reduced and a portion of the subterranean formation is pressurized by injecting a displacement fluid into the subterranean formation. A sample of the fluid pressurized by the displacement fluid is then collected.
