  • Patent number: 11566280
    Abstract: The invention relates to a method for the detection of the occurrence of initiation of replication events in genomic DNA in a eukaryotic cell, involving contacting said eukaryotic cell comprising said genomic DNA with a first nucleotide probe, under conditions enabling in situ hybridization of said first nucleotide probe with a target region in the DNA genome, wherein said target region comprises a nucleic acid sequence which has no identified corresponding annealing RNA in a metabolically active cell and therefore remains RNA-free during transcription and replication of said DNA genome and detecting said first nucleotide probe hybridized to said DNA. Further detection of at least one RNA molecule can be achieved.

  • Patent number: 10732310
    Abstract: A method to model a subterranean formation of a field. The method includes obtaining a seismic volume comprising a plurality of seismic traces of the subterranean formation of the field, computing, based on the seismic volume, a seismically-derived value of a structural attribute representing a structural characteristic of the subterranean formation, computing, based on a structural model, a structurally-derived value of the structural attribute, the structural model comprising a plurality of structural layers of the of the subterranean formation, comparing the seismically-derived value and the structurally-derived value to generate a difference value representing a discrepancy of modeling the structural attribute at a corresponding location in the subterranean formation, and generating a seismic interpretation result based on the difference value and the corresponding location.

  • Publication number: 20160124116
    Abstract: A method, apparatus, and program product may utilize a stratigraphic implicit function, e.g., as used in connection with volume based modeling, to generate structural information for a subsurface formation. In particular, structural information for a subsurface formation may be generated by determining a location in a volume of interest in the subsurface formation from subsurface formation data associated with the subsurface formation, accessing a numerical model having a monotonously varying stratigraphic implicit function defined within the volume of interest to determine a value of the stratigraphic implicit function corresponding to the determined location, and generating at least one structural element for the subsurface formation from the stratigraphic implicit function of the numerical model based upon a spatial distribution of the determined value within the volume of interest.
