Short-period internal multiples, resulting from closely spaced interfaces, may interfere with their generating (bandlimited) primaries, and hence they pose a long-standing challenge in their prediction and removal. A recently proposed method based on

Seismic modelling and inversion often require the calculation of many closely related forward problems. If model perturbations are restricted to a small subvolume, a local wave solver can be an efficient alternative to a wave simulation performed on

Summary Signal apparition using triple source in simultaneous mode has been successfully tested in a field trial at the Grane field in the Norwegian North Sea. When used in a repeat setting, spanning eight months of field history, results show that a

The recently introduced method of `signal apparition' offers a fundamentally different approach to separation of multiple interfering sources, by using a periodic sequence of source signatures along one source line. This leads to exact separation of

We present results from a triple-source signal apparition-style field test carried out over a PRM array in the North Sea during the summer of 2017. In addition to the triple-source line, two reference lines were acquired firing the central source onl
