摘要： Some implementations provide a method that includes: accessing a stream of input data from logging tools in a first well-bore, wherein the stream of input data comprises measurements of bore sizes inside the first well-bore; splitting the stream of input data into a training set of input data and a testing set of input data; training a machine learning model using the training set of input data, wherein the machine learning model is configured to predict a bore size parameter based on input features of the training set of input data; evaluating the machine learning model using the testing set of input data; and in response to evaluating the machine learning model as satisfactory, applying the machine learning model to a newly received stream of input data from a second well-bore such that the bore size parameter of the second well-bore is determined independent of measurements of bore sizes inside the second well-bore.

摘要： Provided in some embodiments are systems and methods for developing a hydrocarbon reservoir. A method may include, for each of a plurality of prosed hydrocarbon wells, determining a reservoir entry point corresponding to a location at a top limiting surface of the hydrocarbon reservoir, determining a reservoir exit point corresponding to a location at a bottom limiting surface of the hydrocarbon reservoir, and determining a well trajectory that includes a path that extends downward gradually from the reservoir entry point at the top limiting surface to reservoir exit point at the bottom limiting surface. The method also including generating a field development plan (FDP) for the hydrocarbon reservoir, the FDP including development information for each well of the plurality of wells, including the determined well trajectory for the well.

摘要： A computer-implemented method that autonomously performs rock drill cuttings interpretation is described herein. The method includes obtaining rock drill cuttings representations. The method also includes preprocessing the rock drill cuttings representations. The method also includes performing unsupervised image segmentation in order to obtain masked representations of such images discriminating rock types. The method also includes performing supervised learning through a custom Convolutional Neuronal Network using the segmented pictures as inputs and a continuous or discrete mineralogical or sedimentological variable of interest as the output. Additionally, the method includes autonomously predicting such mineralogical or sedimentological quantity from new rock drill cuttings pictures using the parameters of the unsupervised segmentation and the trained supervised model created for this purpose.
