  • Patent number: 10677052
    Abstract: The present disclosure generally relates to a real-time synthetic logging method for optimizing one or more operations in a well. The method generally includes receiving measurements of one or more parameters in real time while performing operations in the well, the measurements being captured without using tools that include active nuclear sources. The method further includes providing the measurements as input to a machine learning algorithm (MLA) that is trained using historical or training well data. The method further includes generating, using the MLA and based on the measurements, a synthetic mechanical property log of the well. The method further includes generating, based on the synthetic mechanical property log, optimized parameters for at least one operation selected from the following list: drilling the well in real-time; steering the well in real-time; and stimulating a reservoir in real-time.

  • Publication number: 20200004267
    Abstract: Related are vehicle-following deceleration control method and system. The method includes: acquiring current deceleration of front vehicle and current inter-vehicle time distance between current vehicle and front vehicle; when monitoring that brake lamp of front vehicle lights, performing increase correction on absolute value of current deceleration of front vehicle to obtain deceleration corrected value, and or performing increase correction on preset inter-vehicle time distance threshold of ACC system of current vehicle; and sending a deceleration request by the ACC system of the current vehicle, in a case where an absolute value of the deceleration corrected value is greater than or equal to an absolute value of a preset deceleration threshold of the ACC system of the current vehicle, or the current inter-vehicle time distance between the current vehicle and the front vehicle is smaller than or equal to the inter-vehicle time distance threshold corrected value.
