Abstract: Methods and systems for training a machine learning (ML) network to predict a likelihood of a presence of a geological fracture from an observed drill-bit seismic dataset are disclosed. The method may include obtaining, using a seismic processing system, a plurality of geophysical models, where each geophysical model includes a location of a drill bit. The method may further include simulating, for each geophysical model a corresponding simulated drill-bit seismic dataset for seismic waves emanating from the drill bit and recorded by at least one seismic receiver and forming a training dataset including a plurality of training pairs, with each training pair including a geophysical model from the plurality of geophysical models and the corresponding simulated drill-bit seismic dataset. The method may still further include training, using the training dataset, the ML network to predict the likelihood of the presence of the geological fracture from the observed drill-bit seismic dataset.

Abstract: A system and method map a borehole using LIDAR. The system comprises a tool and a mapping sub-system. The tool includes an intermediate LIDAR sub-system and a distal LIDAR sub-system. The intermediate LIDAR sub-system has an intermediate emitter and an intermediate receiver. The intermediate emitter emits light and the intermediate receiver receives reflected light from the intermediate object. The distal LIDAR sub-system has a distal emitter and a distal receiver. The distal emitter emits light, and the distal receiver receives reflected light from the distal object. The mapping sub-system determines a position of the tool, determines an inner surface of the borehole, and generates and outputs a map of the borehole from the position and the inner surface. A method comprises steps performed during operation of the system.

Abstract: A method for identifying fractures within a geological formation is provided. The method includes obtaining a plurality of images from within a first well located within the geological formation, wherein at least one image of the plurality of images comprises an identified fracture in the geological formation, obtaining a first mudlogging dataset associated with the plurality of images, correlating one or more helium measurements from the first mudlogging dataset with each image of the plurality of images via a machine learning engine to train a machine learning model to obtained a trained machine learning model, obtaining, by the trained machine learning model, a second mudlogging dataset associated with an interval of a second well, and determining a presence of one or more fractures in the interval of the second well by the machine learning model based on helium content determined from the second mudlogging dataset.

Abstract: Systems and methods for evaluating a subsurface region of the earth for hydrocarbon exploration, development, or production are disclosed. Embodiments of the present disclosure are configured to determine advanced radioactive formation data from commonly acquired well logging data sets. In particular, a predictive model is trained to generate “synthetic” spectral gamma ray logs are from basic neutron, density and total gamma ray logs measured from a well within the formation. The predictive model comprises a neural network that is trained using multi-resolution graph clustering techniques to correlate patterns in the density, neutron and gamma ray log data to patterns in spectral gamma ray log data. Embodiments of the present disclosure are further configured to use the synthetic spectral gamma ray logs output by the model to quantify the clay content of the formation, its permeability and determine a hydrocarbon productivity index for the formation.

Abstract: A method for predicting sand production in a formation, including the steps: drilling a well that penetrates the formation, gathering petrophysical formation evaluation (FE) data and Mechanical Earth Model (MEM) data from the well; entering the FE and MEM data as input into a trained model; determining a critical drawdown pressure (CDP) from the output of the trained model; and predicting the sand production from the CDP.
