An apparatus and method that form closed-loop system(s) between a downhole system that includes an RSS and a surface control system, to improve stability and performance assurance of the RSS. The apparatus and method account for the actual downhole conditions experienced by the RSS, the actual positioning of the RSS, and historical performance of the surface systems such as the mud pump system, the rotary drive system, and the draw works. These closed-loop systems generate and optimize parameters or target outputs, instructions to surface systems, and instructions for the RSS itself.

A method that includes an electronic application identifying an ending of a first drilling segment and a simultaneous beginning of a second drilling segment; identifying a data set of the first drilling segment; automatically creating, in response to the identification of the first drilling segment ending, a new row in a database table that stores a data set for each drilling segment, with the new row storing the variable values of the first drilling segment; creating a multi-dimensional data matrix based on the values in the database table; and extracting, from multi-dimensional data matrix, an optimum value of a variable for an upcoming drilling segment. The method may also include determining that a trajectory or location of a rotary steering system is outside of a tolerance window; and the step of extracting the optimum value of the variable is in response to this determination.

A method can include acquiring data associated with a field operation in a geologic environment; processing the data by partitioning operationally and representing symbolically; formulating a symbolic query for an operating procedure specification; performing a search of the symbolically represented data utilizing the symbolic query and a probabilistic chain model; receiving a search result responsive to the search; assessing compliance with the operation procedure specification utilizing the search result; and issuing a control signal to field equipment utilizing the assessment of compliance.

Dynamic field operations system

A method of identifying an instruction combination executable by a surface control system of a drilling rig to change settings of a rotary steerable system ('RSS') tool. The method includes identifying, by an electronic application, a first current RSS setting of the RSS tool; identifying, by the electronic application, a first target RSS setting of the RSS tool; identifying, by the electronic application, a plurality of instruction combinations configured to change the first current RSS setting to the first target RSS setting. Each instruction combination of the plurality of instruction combinations comprises a number of steps, and each step includes a downlink command sequence. The method also includes selecting, by the electronic application, an instruction combination that comprises the least number of steps.

A method and apparatus for oil and gas operations according to which a bottom hole trajectory of a drilling well is surveyed using a survey tool located uphole from a drill bit positioned at a bottom hole location. One or more offset wells are identified having a trajectory, or respective trajectories, closing on the bottom hole trajectory of the drilling well. An anti-collision steering strategy for the drilling well to avoid the one or more offset wells is determined.
