Abstract: Methods and systems for determining a well shut-in pressure of oil and gas well drilling are provided. The method comprises: obtaining, by a first processor, a basic parameter of a target oil and gas well, the basic parameter including at least one of a wellbore structure parameter, a well drilling fluid performance parameter, or a casing string parameter; obtaining, by the first processor, a pressure calculation model; and determining, by the first processor, a maximum well shut-in pressure during well drilling of the target oil and gas well based on the pressure calculation model and the basic parameter.

Abstract: Techniques for efficiently processing Bayer image data to generate a final image that realistically and properly reproduce an original scene are disclosed. According to one implementation, a method for processing Bayer images comprises receiving a raw image from a sensor with Bayer color arrays, determining a corresponding dot in the raw image that corresponds to each pixel in a final image, locating color reference pixels in the raw image according to the corresponding dot, selecting interpolation pixels in the raw image according to the color reference pixels, and interpolating color values of the each pixel in the final image according to color values of the interpolation pixels.
