3-D
Geometry for Minimizing Acquisition Footprint
BGP, CNPC
To have a reliable interpretation, geologists need reliable
seismic information. The acquisition footprint caused by 3-
D geometry gains more and more attention from
geoscientists. This paper first analyzes the influence on
acquisition footprint due to 3-D
geometry parameters such
as receiver line interval (RLI), shot line interval (SLI),
cross-line roll distance, different patterns of geometry and
different depths of targets through building up an ideal
model and then clarifies the direction of efforts to minimize
the acquisition footprint through designing of
3-D
geometry. Secondly, the paper proposes optimal
3-D
geometry design compromising the field acquisition cost
and acquisition footprint without sacrificing geologic target.
