Real-time interpretation
has significant
implications for the E&P industry. The
ability to reach an
interpretation
while fundamental
exploration and production processes
are underway holds the promise of
substantially improving outcome while
acquiring
data
, drilling wells, and managing
reservoirs. "Real time" means that
data
can be visualized and interpretations performed
during acquisition, processing,
drilling, and production. "
Interpretation
" in
this context includes all the tasks needed
for forming a consistent 3-D subsurface
model:
data
processing, analysis, modeling
structural and stratigraphic
interpretation
,
reservoir simulation, and model integration
with production
data
.
The benefits of real-time interpretation
are
significant. If interpretations are performed
while acquisition is underway, the turnaround
time for drilling decisions can be
significantly shortened. In addition, navigation
and
seismic
data
can be quality
controlled much more effectively with full
processing
interpretation
during the acquisition
phase. With respect to drilling, not
only can the target area be hit more effectively
if it is visualized, but there is a substantial
reduction in blowout risk with
real-time
interpretation
. Finally, reservoir
management can be done much more
effectively with the ability to continuously
update the model during production.
To achieve real-time interpretation
, new
information technology is needed. Real-time
3-D
data
processing during acquisition
requires fast parallel computers
together with appropriately parallelized
software. Effective utilization of different
data
types from separate locations requires
new information access tools such as
interactive video teleconferencing. The
ability to visualize 3-D
data
with embedded
interpretation
requires new voxel-based
technology. Synthesis of all
data
types and
interpretation
requires a software framework
such as TerraCube, OpenWorks, or
GeoFrame.
The goal for real-time interpretation
is to
improve outcome through better and faster
decisions. The method for achieving this
goal is to use new technology to provide a
more accurate and comprehensive understanding
of the subsurface and to minimize
time spent by the interpreter searching for
projects, reformatting
data
, and learning
new software. The user remains the critical
element of the system because it is the
user who exercises the judgment, imagination,
and creativity to make final decisions,
and it is the user who will make these decisions
in real time while processes are
underway in order to improve outcome.
