The reference curve may be generated by a weak learner machine learning model. The weak learner machine learning model may preserve shape characteristics and depth information of one or more input curves in the reference curve. Depth shifting of a target well log may be performed by iteratively using sliding correlation windows of differing sizes.

QUANTIFICATION OF LIQUID AND CORRECTION OF GAS FLOW RATE IN A GAS PIPELINE USING PHASE BEHAVIOR
Fluid composition inside a pipe and operating condition (e.g., temperature, pressure) inside the pipe are used to determine liquid quantity in the pipe. The liquid quantity in the pipe is used to determine whether liquid is present in the pipe. If liquid is present in the pipe, over/under reading of gas flow in the pipe may occur, and the over/under reading of gas flow in the pipe is used to correct gas flow rate measurement in the pipe. Liquid flow rate may also be determined.
