Utilizing look-up tables representing all models in an automation control architecture to independently handle uncertainties in sensed data in oil and gas well construction

A computer program product for utilizing look-up tables representing all models in an automation control architecture to independently handle uncertainties in sensed data, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code comprising the programming instructions for:

• storing data in a form of conditional probability tables or conditional probability distributions, wherein said data comes from the following sources:
• an operator, a service provider, a drilling contractor and an equipment manufacturer, wherein said data from said operator comprises information regarding well planning and construction, wherein said data from said service provider comprises data from surface sensors and downhole telemetry tools, wherein said data from said drilling contractor comprises data regarding a working condition of rig equipment, wherein said data from said equipment manufacturer comprises data regarding equipment performance characteristics, wherein said conditional probability tables are matrices or multi-dimensional arrays that represent probabilistic relationships between various drilling parameters, wherein said conditional probability distributions are continuous variants of said conditional probability tables;
• receiving models of a drilling process comprising one or more of the following domains:
• wellbore hydraulics, drill bit/rock interactions, rock/fluid interactions, wellbore geomechanics, torque and drag modeling, vibration modeling and drilling machinery operation;
• extracting data from said models into said conditional probability tables or conditional probability distributions;
• converting said conditional probability tables or conditional probability distributions into look-up tables;
• and
• visually displaying data in said look-up tables in graphical form.
