Maximising the value of 2D hard rock seismic acquisition at Escondida Porphyry Copper Mine

Abstract

In mining areas with limited previous seismic acquisition, 2D seismic lines are often acquired to determine viability of the method and optimal survey parameters in advance of a more comprehensive 3D survey. Consideration of the design and acquisition strategy can allow additional value to be leveraged from the nominally 2D data. At Escondida, four 2D lines were processed to yield a pseudo-3D volume over a portion of the survey area, allowing improved structural interpretation above what could be achieved from 2D imaging alone.
