To detect the existence of crude oil, exploratory drilling is the only way to know whether there is oil in the subsoil. Suppose the results of the exploratory drilling are positive. In that case, a program of drilling advanced wells that delimit the structure geologically is initiated. Then, the development wells are drilled, which exploits the field by extracting the oil [4]. Detecting oil requires a knowledge of the geology of the subsoil. Part of this knowledge is obtained through seismic experiments, which generate seismic waves whose echoes, recorded on the surface, provide information about the Earth's interior. In this case, the numerical modeling of seismic data has been used to support the interpretations of a dataset from these experiments [5]. Several numerical techniques have been developed to model wave propagation, Including, among others, finite difference, finite element, Fourier, or pseudo-spectral methods. Finite difference techniques are widely used and particularly attractive for complex subsurface geometries due to the easy computational implementation of boundary conditions [6]. This paper uses the finite difference method to approximate the two-dimensional acoustic wave equation for heterogeneous media using second-order differences of accuracy that are solved iteratively by spatial and temporal discretizations. To obtain more realistic information about the subsurface, signal-emitting sources are placed in different horizontal locations, which involves a high computational cost since, for extensive geological profiles, many sources would be needed to create a seismogram associated with each emitter [7] and the final seismogram is obtained by superimposing each of the placed sources.
