  • Publication number: 20230117321
    Abstract: Techniques are disclosed relating to deblending of sources in multi-source geophysical survey data, including marine or land-based data. Multiple sets of deblended receiver traces are generated by iteratively applying a coherency filter to estimated sets of deblended receiver traces and updating a residual until a termination condition is reached. In some embodiments, applying the coherency filter during a current iteration may include determining coefficients of the coherency filter based on estimated sets of deblended receiver traces from an immediately prior iteration. In further embodiments, applying the coherency filter may include applying a 3D projection filter, such as an fxy projection filter.

  • Patent number: 11614003
    Abstract: A combined cooling, heating and power system is formed by integrating a CO2 cycle subsystem, an ORC cycle subsystem, and an LNG cold energy utilization subsystem based on an SOFC/GT hybrid power generation subsystem. The combined system can achieve efficient and cascade utilization of energy and low carbon dioxide emission. An SOFC/GT hybrid system is used as a prime mover. High-, medium-, and low-temperature waste heat of the system are recovered through CO2 and ORC cycles, respectively. Cold energy (for air conditioning and refrigeration), heat, power, natural gas, ice, and dry ice can be provided by using LNG as a cold source of the CO2 and ORC cycles. Low CO2 emission is achieved by condensation and separation of CO2 from flue gas, so energy loss of the system can be reduced, and efficient and cascade utilization of energy can be achieved, thereby realizing energy conservation and emission reduction.

  • Patent number: 11567226
    Abstract: Techniques are disclosed relating to deblending of sources in multi-source geophysical survey data, including marine or land-based data. Recorded data may be aligned to a primary source. A deblending procedure may be iteratively applied to produce a residual term and deblended estimates for the primary source and one or more secondary sources. Following an iteration of the deblending procedure, the resultant data may be sorted according to a domain that renders the one or more secondary sources incoherent with respect to the primary source. The domain used for sorting may be different from a domain used to sort during an immediately prior iteration. In embodiments, the deblending procedure may use coherency filtering, and the coherency filtering may be weighted according to a signal-to-noise metric generated from the data being deblended.
