Abstract: A system and method for accessing drilling records. A semantic web for drilling records is built, wherein building includes converting drilling records retrieved from a database into a Resource Description Framework (RDF) format and storing the RDF formatted drilling records in the semantic web. Transfer learning is applied to drilling domain knowledge to obtain a large language model (LLM) with drilling domain knowledge. A schema is applied to unstructured records to extract information from unstructured records and the extracted information is then stored in RDF format to the semantic web. The LLM is configured to query the semantic web and to manipulate RDF formatted data within the semantic web.

Abstract: Methods and systems are provided for monitoring operational characteristics of a drilling system that includes a bottom hole assembly having a drill collar operably coupled to a drill bit. A device having an elongate beam and at least one pair of sensors is rigidly secured to a part of the bottom hole assembly to measure strain in the part of the bottom hole assembly. The measurement of strain can be used to derive a measurement of at least one operational parameter of the drilling system, such as dog leg severity of a wellbore, torque on bit, and/or weight on bit.

Abstract: A method of operating a downhole system includes receiving trajectory data including a trajectory for steering a downhole tool toward a downhole target. The method includes identifying downhole tool data for the downhole tool. The method includes, based on the trajectory data and the downhole tool data, predicting one or more engineering metrics including one or more downhole tool metrics associated with an operation of the downhole tool in accordance with the trajectory and one or more completion metrics associated with a completion of the borehole at the downhole target. The method includes determining a coherency for the trajectory including determining whether the engineering metrics are within one or more predetermined thresholds. The method includes generating a report of at least some of the engineering metrics including a value of each engineering metric and an indication of whether the value is within the predetermined thresholds.

Abstract: Systems and methods for identifying an unconformity in a subsurface formation include collecting well log measurements from a set of wells in the subsurface formation and collecting core samples from a first subset of the set of wells. A second subset of wells without lithology contrast is identified. Fractures and bedding planes are characterized in borehole image logs for wells in the second subset. For wells in the first and second subsets, the location of the unconformity is determined based on the core samples, and correlations are generated between the determined location of the unconformity and the identified fractures and bedding planes in the borehole image logs. For wells in the second subset and not in the first subset: the location of the unconformity is determined based on the identified fractures, bedding planes, and generated correlations. An unconformity surface is generated.

Abstract: System and method for determining the location of a bottom hole assembly (BHA) during drilling of a well are provided. During drilling, a computer system determines an increase in measured depth during a time interval, and adjusts the determined measured depth to account for tensile and compressive forces, which may stretch or compress, respectively, the length of the drillstring. The computer system also determines a curvature projection of the drillstring responsive to a plane of arc and a build rate estimate, and uses the curvature projection to determine a position of the BHA.

Abstract: Processes to receive user input parameters and system input parameters associated with a borehole undergoing active drilling operations to continually update drilling directions with wholistically applied optimizations to bring the actual borehole trajectory closer to the planned borehole trajectory. The processes can project ahead of the drilling assembly to determine the actual trajectory of the borehole and generate corrections to reduce the gap between the actual and planned trajectory paths. Various optimizations can be applied to the corrections to avoid overstressing systems or reducing the borehole productivity. Conflicts between optimizations can be resolved using a weighting or ranking system. More than one set of corrections can be determined and a user or a machine learning system can be used to select the one set of corrections to use as the results to be communicated and applied to the drilling operation plan or a borehole system, such as a geo-steering system.

Abstract: A method includes assembling a model including a plurality of independent objects. The independent objects include surfaces, properties, and zones. The method also includes decomposing the model into vertical columns, tiles, or both. The method also includes discretizing an incoming request into the vertical columns, the tiles, or both. In response to the discretized request, the method also includes performing a vertical pin analysis on the model to retrieve a portion of the surfaces, a portion of the properties, or both that are geo-located in the vertical columns, the tiles, or both. The method also includes modelling the retrieved portions to generate an output. The method also includes comparing the output with subsurface data. The method also includes modifying the model based at least partially upon the comparison.

Abstract: Dynamic offset well analysis includes receiving a selection of a set of parameters on a well plan comparison tool displayed in a graphical user interface (GUI). For each parameter that is selected, a selection of a set of weights is received from the well plan comparison tool. Dynamic offset well analysis also includes weighting parameter values for objects according to the set of weights. Dynamic offset well analysis additionally includes analyzing the objects according to the weighted parameter values to form clusters. The clusters are then displayed on the well plan comparison tool in the GUI.
