DOI: 10.1007/s11770-018-0697-2
Abstract: Finite-difference (FD) methods are widely used in seismic forward modeling owing to their computational efficiency but are not readily applicable to irregular topographies. Thus, several FD methods based on the transformation to curvilinear coordinates using… read more here.

DOI: 10.1016/j.epsl.2019.02.011
Abstract: Abstract Sandstone intrusions form large bedding-discordant sandstones that intruded into finer grained, less permeable host strata. They form naturally sand-propped hydraulic fractures that constitute a connected network of permeable conduits through which fluids escape to… read more here.
