Start
with regional 2-D reconnaissance lines
Following
the initial discovery – detailed 2-D or 3-D
Repeated
3-D surveys (“time-lapse”, or 4-D) for monitoring changes in the area during production
For
best survey planning:
nIn most cases, need to have a good idea about
the target
nUse computerized pre-acquisition
modelling
Key
considerations:
nFor 2-D – lines should be oriented
across-strike of the target structures
nCost – minimize the number of source
points
nAchieve sufficient multiplicity (“fold”) of
coverage
nAchieve uniformity of coverage of the target
horizons
n“Undershoot” obstacles and survey edges
nAchieve adequate resolution and fidelity
nReduce the acquisition footprint (especially
important in 3-D)
