  • Patent number: 12148419
    Abstract: Mechanisms are provided for performing machine learning training of a computer model. A perturbation generator generates a modified training data comprising perturbations injected into original training data, where the perturbations cause a data corruption of the original training data. The modified training data is input into a prediction network of the computer model and processing the modified training data through the prediction network to generate a prediction output. Machine learning training is executed of the prediction network based on the prediction output and the original training data to generate a trained prediction network of a trained computer model. The trained computer model is deployed to an artificial intelligence computing system for performance of an inference operation.

  • Patent number: 12099461
    Abstract: Methods and apparatus relating to techniques for multi-tile memory management. In an example, an apparatus comprises a cache memory, a high-bandwidth memory, a shader core communicatively coupled to the cache memory and comprising a processing element to decompress a first data element extracted from an in-memory database in the cache memory and having a first bit length to generate a second data element having a second bit length, greater than the first bit length, and an arithmetic logic unit (ALU) to compare the data element to a target value provided in a query of the in-memory database. Other embodiments are also disclosed and claimed.

  • Patent number: 11163080
    Abstract: A computer implemented method is provided for generating a subsurface rock and/or fluid model on a determined domain. The subsurface rock and/or fluid model generated by the invention combines acoustic data and data obtained by an electromagnetic survey in such a way that the resulting model avoids the need of generating an image of the resistivity with the low resolution imposed by the known techniques inverting EM electromagnetic survey data.

  • Patent number: 8265913
    Abstract: A method of analysing results from a controlled source electromagnetic survey of a region of interest containing a previously identified geological structure suitable for bearing hydrocarbons is described. The method comprises providing a first survey data set obtained outside the region of interest, i.e. off-target, for a range of source-receiver orientations and offsets, and providing a second survey data set obtained inside the region of interest, i.e. on target, for a range of source-receiver offsets. The method further comprises performing a mathematical inversion of the first survey data set to provide a model of the subterranean strata outside the region of interest, and processing the second survey data set to provide a model of the subterranean strata inside the region of interest, wherein the processing of the second survey data set takes account of the results of the inversion of the first survey data set.

  • Patent number: 8099239
    Abstract: A method of analyzing electromagnetic survey data from an area of seafloor (6) that is thought or known to contain a conductive or resistive body, such as a subterranean hydrocarbon reservoir (12), is described. The method includes providing electric field data and magnetic field data, for example magnetic flux density, obtained by at least one receiver (25) from a horizontal electric dipole (HED) transmitter (22) and determining a vertical gradient in the electric field data. The vertical gradient in the electric field data and the magnetic field data are then combined to generate combined response data. The combined response data is compared with background data specific to the area being surveyed to obtain difference data sensitive to the presence of a subterranean hydrocarbon reservoir.

  • Patent number: 7592814
    Abstract: A method of analyzing electromagnetic survey data from an area of seafloor 6 that is thought or known to contain a resistive or conductive body, for example a subterranean hydrocarbon reservoir 12, is described. The method includes providing horizontal electromagnetic field data obtained by at least one receiver 125 from at least one horizontal electric dipole transmitter 22. Horizontal gradients in the electromagnetic field data are determined for a first component of the electromagnetic field data along a first direction and for a second component of the electromagnetic field data along a second direction. The first and second components can be the electric field along the first and second directions, or the magnetic field perpendicular to the first direction and second directions. The gradients are then combined to provide combined response data.

  • Patent number: 7565245
    Abstract: A method of analysing results from an electromagnetic survey of an area that is thought or known to contain a subterranean resistive or conductive body within a background strata configuration is described. The method comprises providing a set of electromagnetic field data obtained using at least one electromagnetic receiver and at least one electromagnetic source for a range of source-receiver separations, e.g. providing conventional controlled-source electromagnetic survey data. A subset of the electromagnetic field data is identified that comprises data obtained for source-receiver separations greater than a selected threshold offset. The threshold offset is chosen so that data beyond this offset are characteristic of magnetotelluric data. Thus the subset of data is then processed in accordance with a first technique to obtain information on the background strata configuration.
