Claim 0:
1. A method for processing downhole multisensor data representative of a well operations, the method comprising:
using a physics-informed model, representative of function of a well operations, coded into one or more computer systems;
using a fitting constant related to at least one of a reservoir rock, a fluid, a thermal, a completion, and a wellbore intervention property;
updating the physics-informed model using a surrogate model that improves computational speed and is acceptably accurate to provide an updated physics-informed model;
generating a prior probability distribution function using the physics-informed model;
repetitively fusing input data originating continuously from at least a first downhole sensor and a second downhole sensor with the prior probability distribution function to generate a posterior probability distribution function, wherein the input data comprises a first value of a first physical property sensed by the first downhole sensor and a second value of a second physical property sensed by the second downhole sensor, the second physical property being different from the first physical property, and the method further comprises calculating a third value of a third physical property different from the first and second physical properties using the first and second values, wherein the first downhole sensor and the second downhole sensor are coupled to a drill tubular drilling a borehole in a formation and perform measurements while the borehole is being drilled; and
processing the posterior probability distribution function with one or more computer systems to generate in real-time an output.
