Den Blicherske Novelle.
In his texts Regin í Líð, as the first writer
in modern Faroese prose fiction, describes
social conditions, leelings, sexuality etc.
His texts are, with respect to language as
well as literary merit, pioneer works.

Innspræning av gass hevur stóran týðn-

so er gassinnspræning rnest gagnlig tá hon

Upscaling of
Miscible Displacement.
Accurate predictions of reservoir flow and
recovery is important for planning a de-
velopment of an oil and gas field. To ac-
complish this task, đetailed and accurate
information are required about the reservoir
geology and the fluid types occupying the
porespace in the reservoir. Further more ac-
curate and robust models for fluid-fluid and
fluid-rock interactions are needed.
Gas injection has become very important as
a means to increase oil recovery as well as
for environmental considerations in oil field
development. As a means to increase oil re-
covery, gas injection processes are most ef-
fective when the injected gas is nearly or
completely miscible with the oil in the res-
ervoir. In theory it is possible to recover all
the oil by a miscible displacement.
It is possible to simulate such processes
