  • Patent number: 10317551
    Abstract: The present disclosure provides a technique for marine seismic imaging that processes data acquired from two or more different seismic surveys in a combined manner to advantageous effect. The different seismic surveys may use seabed sensors at same positions on the seabed, but they may have different shot locations and may be performed at different times. In one use case, the technique may be used to image a subsurface location that is difficult to image using either survey alone. In another use case, the technique may be used to image a subsurface location under an obstruction. The technique may also be utilized to efficiently monitor a reservoir over time.

  • Patent number: 10310122
    Abstract: A method for increasing similarity between a first seismic dataset and a second seismic dataset from at least one seismic survey of a subsurface. The first and second seismic datasets are migrated to a dip angle image domain. The migrated first and second seismic datasets are used in the dip angle image domain to calculate a set of decimating weights to be applied to the first seismic dataset and the second seismic dataset to maximize a similarity between the first seismic dataset and the second seismic dataset. The decimated weights are applied to the first and second seismic datasets, and an image of the subsurface is generated using the first seismic dataset and the second seismic dataset following application of the decimated weights.

  • Patent number: 10302785
    Abstract: A method for estimating in real time the geomechanical properties using drilling data and an accurate drilling model. An initial structural framework and initial distribution of the geomechanical and other rock properties is adjusted in real time by estimating accurately the corrected mechanical specific energy (CMSE), which is then used to estimate the geomechanical and other rock properties. For example, the updated geomechanical model can be used to geosteer the well toward the brittle zones that will achieve the best stimulation when using hydraulic fracturing in unconventional wells.

  • Patent number: 10295690
    Abstract: A method and apparatus for seismic sensing is described. The apparatus includes an outer cable coupled to a formation and an outer fiber component proximate to the outer cable. When seismic P- and S-waves propagate from the formation to the outer cable, strain is placed on the outer fiber cable, which may be measured by a distributed acoustic sensing system coupled to the outer fiber cable. An inner cable positioned within the outer cable includes a corresponding inner fiber component. The innerduct between the outer and inner cables is filled with a gas or fluid which allows only P-waves to propagate to the inner cable. Those P-waves induce strain on the inner fiber component, which may be measured by the distributed acoustic sensing system. By measuring the seismic P- and S-waves at the outer fiber component, and the isolated seismic P-wave at the inner fiber component, it is possible to calculate an isolated seismic S-wave measurement. Methods for deploying the seismic sensing apparatus are also described.

  • Patent number: 10286981
    Abstract: A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and source. A floatation device supports the source and tows below the water's surface to avoid ice floes. The streamers can have vehicles deployed thereon for controlling a position on the streamer. To facilitate locating the streamers, these vehicles on the streamers can be brought to the surface when clear of ice floes so that GPS readings can be obtained and communicated to a control system. After obtaining readings, the vehicles can be floated back under the surface. Deploying, using, and retrieving the system accounts for ice at the surface in icy regions. In addition, handling the seismic record can account for noise generated by ice impact events.
