Oil companies with a huge collection of seismic data, either manage the data at their own site or outsource to companies like Schlumberger to maintain a repository of seismic data. Therefore, companies like Schlumberger, have to maintain a common datastore with client ownership. Also, the companies like WesternGeco, which store the data for clients, are in business of selling speculative survey seismic data collected for multiple clients. The ownership could be a partial data of a 2D line or 3D survey.
