1. A method of forming a seismic image of a subterranean region of interest, comprising:
determining an initial plan for a seismic survey over the subterranean region of interest, wherein the initial plan comprises a value for each member of a set of acquisition parameters;
acquiring a first seismic dataset from a first portion of the seismic survey based, at least in part, on the initial plan;
transmitting the first seismic dataset to a seismic processor;
determining a first seismic image from the first seismic dataset by performing expedited seismic processing of the first seismic dataset using the seismic processor;
determining a first updated plan for the seismic survey based on the first seismic image;
acquiring a second seismic dataset from a second portion of the seismic survey based, at least in part, on the first updated plan;
transmitting the second seismic dataset to the seismic processor; and
determining the seismic image of the subterranean region of interest based, at least in part, on the first seismic dataset and the second seismic dataset,
wherein expedited seismic processing comprises:
determining a seismic velocity model using a fast beam tomography workflow; and
forming the first seismic image using the seismic velocity and a fast beam migration method.
