摘要： A method and apparatus for hydrocarbon management, including generating a fluid saturation model for a subsurface region. Generating such a model may include: performing a brine flood petrophysical inversion to generate inversion results; iteratively repeating: classifying rock types (including at least one artificial rock type) based on the inversion results; generating a trial fluid saturation model based on the classified rock types; performing a trial petrophysical inversion with the trial fluid saturation model to generate trial results; and updating the inversion results with the trial results; and generating the fluid saturation model for the subsurface region based on the inversion results. The petrophysical inversion may include a facies-based inversion and/or may invert for water saturation. Generating such a model may include: performing a brine flood petrophysical inversion, performing a hydrocarbon flood petrophysical inversion; identifying misfits in the inversion results, and generating a trial fluid saturation model based on the misfits.

摘要： A method for hot stamping an iron based component in which the component is heated to a temperature sufficient to transform the component into austenite. The heated component is then positioned in an open stamping die and the stamping die is closed to mechanically change the shape of the heated component to a desired end shape of the component. At least one opening is punched in the heated component and, thereafter, the component is quenched at a rate and to a temperature sufficient to transform the component into martensite.

摘要： One embodiment of an optical fiber for reducing insertion loss and insertion loss ripple includes a tapered region where the optical fiber has a diameter of approximately 125 microns at a first end and a diameter of approximately 50 microns at a second end. The cladding layer of the tapered region is tapered from the first end towards the second end. This section of the optical fiber may be tapered using an etch process or any other technically feasible process. The tapered configuration enables the distance between the optical axes of two optical fibers inserted into a ferrule to be reduced from approximately 125 microns to approximately 50 microns. Decreasing the distance between the optical axes causes a reduction in both insertion loss and insertion loss ripple.

摘要： A multi-stage FWI workflow uses multiple-contaminated FWI models to predict surface-related multiples. A method embodying the present technological advancement, can include: using data with free surface multiples as input into FWI; generating a subsurface model by performing FWI with the free-surface boundary condition imposed on top of the subsurface model; using inverted model from FWI to predict multiples; removing predicted multiples from the measured data; using the multiple-free data as input into FWI with absorbing boundary conditions imposed on top of the subsurface model; and preparing a multiple free data set for use in conventional seismic data processing.

摘要： One embodiment of the present invention includes a plurality of first optical elements and a second optical element optically coupled to one another in cascaded fashion. Each first optical element has a group delay response characterized by a first period such that only one group delay peak occurs within a first channel. By contrast, the second optical element has a group delay response characterized by a second period, which is less than the first period, such that more than one group delay peak occurs within the first channel. The preferred embodiment uses cascaded GT etalons to provide the desired group delay responses. One advantage of the present invention is that the passband of the dispersion compensator is increased relative to prior art designs without increasing insertion losses. Alternatively, the same passband common in prior art designs may be achieved with fewer GT etalons, thereby reducing insertion losses.
