Abstract: Methods and systems for stream processing in a distributed event data store system. The systems comprise a stream processor system configured to: consume, in real-time, a stream of events stored in a topic by a set of one or more event streaming routers; stream the consumed events to the set of one or more event streaming routers for storage in a compacted topic; update data in a local store of the stream processor system based on the events in the compacted topic; periodically query the local store to determine if one or more conditions is met; and in response to determining that at least one condition of the one or more conditions is met, take an action.

Abstract: Seismic data is deblended by performing, for each receiver, a first inversion and a second inversion in a transform domain. The first inversion is formulated to minimize a number of non-zero coefficients of the first inversion result. A sub-domain of the transform domain is defined by vectors of a transform domain basis for which the first inversion has yielded the non-zero coefficients. The second inversion is performed in this sub-domain. The solution of the second inversion is used to extract deblended seismic datasets corresponding to each of the distinct signals, from the seismic data.
