Abstract: This invention relates to a method of correcting eccentricity of ultrasonic image profiles, measured along a section of rock, including the steps of measuring emitted amplitude values (A0) and measuring transit time values (tθ) of ultrasonic acoustic pulses emitted at a range of default angles (θ), where the amplitude measured at each angle (Aθ) is determined by an amplitude decay model in relation to the transit time (tθ) defined by A θ=Aθ·etθ/τ·Iθ, where τ is the decay correction factor; and Iθ is the reflection coefficient of the rock wall.

Abstract: The present invention is related to production schedules in a refinery and, more particularly, refinery production schedules by genetic programming in domain specific language. In this scenario, the present invention provides a method and an optimization system based on linear genetic programming oriented to grammar and with quantic inspiration using a domain specific language for the solution of oil programming problems, in addition to a readable medium comprising instructions to perform this said method. More specifically, the quantic chromosome keeps the superposition of states of all possible solutions and, through the evolutionary process and observation of quantic genes, the classical chromosome is created as a linear sequence of instructions to be performed. The performed instructions represent the scheduling. The orientation of this process is made through the use of a multiple-goal competence function that ranks evaluations about the operation time of the distillation units, the time for unloading ships, the use of the pipeline that moves oil between the terminal and the refinery, as well as factors such as the number of tanks exchanges and use of injection tanks in the distillation units.
