Patent number: 9915742Abstract: Method and system are described for generating a stratigraphic model of a subsurface volume. Measured geophysical data are converted into a vector volume (106) by assigning to each sample in each trace in the data volume a vector representing dip, azimuth or confidence. Then a labeled volume is generated from the vector volume by assigning a label to each sample in an initial trace (1006), then selecting a propagation pattern (1008) and propagating the labels to other traces (1010). Horizons can be extracted (110) from the labeled volume, and utilized to enhance the process of producing hydrocarbons (114).Type: GrantFiled: November 18, 2013Date of Patent: March 13, 2018Assignee: ExxonMobil Upstream Research CompanyInventors: Pavel Dimitrov, Matthias Imhof

Patent number: 9915745Abstract: At least some embodiments are directed to a system. The system includes a processor and a memory coupled to the processor. The memory stores a program that, when executed by the processor, causes the processor to calculate a pressure response of a first sensor, and correct pressure wavefield data obtained from the first sensor responsive to a first acoustic wavefield. The correction is based on the calculated pressure response of the first sensor. The pressure response of the first sensor is responsive to a second acoustic wavefield having a propagation path between a source of the second acoustic wavefield and the first sensor, in which the propagation path includes no reflection from a subsurface formation.Type: GrantFiled: March 30, 2016Date of Patent: March 13, 2018Assignee: PGS Geophysical ASInventors: Stian Hegna, Tilman Kluver
