Abstract: A method for, at least, forming a graph representation of physical samples and identifying clusters of the physical samples. The method includes obtaining a plurality of physical samples from one or more wells, where each sample is associated with spatial-temporal data, and determining geochemical data for each sample. The method further includes constructing a graph representation of the plurality of physical samples, where in the graph representation each sample is represented as a node and a presence of an edge between any two nodes is based on the spatial-temporal data of the plurality of physical samples. The method further includes determining a weight for every edge in the graph representation and processing the graph representation with a graph-based algorithm to determine one or more clusters. The method may further include determining a wellbore plan that comprises a planned wellbore path to penetrate a hydrocarbon reservoir based on the determined clusters.

Abstract: A method for facilitating drilling of a prospect involves, for a multitude of offset wells associated with the prospect, obtaining offset well data, the offset well data including surface drilling parameters, mud gas data, and formation pore pressure data. The method further involves training, using the offset well data, a machine learning (ML) model to make formation pore pressure predictions, where the offset well data used for training the ML model excludes the offset well data of an offset well in closest proximity to the prospect. The method also involves generating a formation pore pressure profile prediction for the prospect prior to drilling the prospect by making formation pore pressure predictions for the offset well in closest proximity to the prospect using the ML model operating on the offset well data of the offset well in closest proximity to the prospect.

Abstract: A method includes placing a rock sample in an inert environment in an oven, heating the rock sample in the oven at about 300° C. for between about 3 and 4 minutes, increasing the temperature to about 750° C. at a rate ranging between 50° C. per minute and 60° C. per minute, and detecting pyrolysis material from the rock sample by a flame ionization detector.
