Rubis sits between single cell material balance and
massive simulation models. It replaces neither, but
does much of the work of both. It offers full-field,
3
D, multiwell, multiphase with gravity capability.
It was developed after seeing engineers labor with
spreadsheets or conventional simulators to solve day-
to-day problems.
The basic premise is that the grid is a necessary
evil that should not dominate the problem solving
process, so it is built automatically. Of real interest is
the physical problem we want to simulate. We want
this to be complex enough to reproduce the main
drives of the reservoir that will affect production, but
simple enough to be run with a very short time cycle
that is usable; in hours, not days.
Recent developments in Rubis have focused on
unconventional resources with multiple-fracture
horizontal wells and wells with arbitrary trajectories;
the Wriggly wells.
‘
Just before lunch the reservoir manager walked in
and asked me to run a few scenarios for the next well
placement. I had the answers on his table by close of
business that day.’
‘
I will never use Rubis to replace my current model. It has
taken so long to build it makes little sense to do so. What I
can do though is runmy cases inRubis and it getsme very
close to what I think is happening. This drastically saves
time in advancing the full model.’
‘
I should not say this, but working with Rubis is fun.
It is the way it should be.’
Rubis, the full-field numerical module of the Ecrin workstation, offers the
specialist and non-specialist alike, an easily built click-and-draw model in
minutes as opposed to hours or days. Multiple forecasts, reserves and
investigation of possible intervention opportunities can be run and history
matched in a very short time frame.
