Abstract: A method can include receiving real-time, time series data from equipment at a wellsite that includes a wellbore in contact with a fluid reservoir; processing the time series data as input to a trained machine learning model to predict a future solids event related to influx of solids into the wellbore from the fluid reservoir; and outputting a time of the future solids event.

Abstract: Digital image processing a digital image of sample drill cuttings retrieved from a geological formation and related methods include identifying individual zones in the image that depict at least a predetermined minimum heterogeneity of a first physical property, extracting particles in each identified zone that depict a second physical property within a predetermined quantitative range, and measuring a third physical property of each extracted particle. The first physical property may be texture, size, color, or spectral response within the zone. The second physical property may be brightness, color, contrast, hue, saturation, or wavelet energy. The third physical property may be size or color.

Abstract: Methods and systems for increasing normalized production rate of an oil and gas reservoir by optimizing the pressure drawdown of the subsurface formation are disclosed. The method includes determining permeability of the subsurface formation as a function of effective stresses, determining stress sensitivity factor, upscaling the permeability values determined for the core sample, determining the optimum pressure drawdown for the subsurface formation, controlling the pressure drawdown in a field operation such that it does not exceed the optimum pressure drawdown for the subsurface formation.

Abstract: Methods are provided for characterizing organic matter in a geological rock formation that perform a Raman spectroscopy measurement on a rock sample of the formation to acquire a Raman spectrum of the rock sample. At least one processor is used to perform operations that involve i) analyzing the Raman spectrum of the rock sample to determine data characterizing at least one Raman spectral feature corresponding to the rock sample, ii) inputting the data characterizing the at least one Raman spectral feature corresponding to the rock sample into a computation model that determines a value of a property of organic matter in the rock sample given the data characterizing the at least one Raman spectral feature as input, and storing or outputting or displaying the value of the property of organic matter in the rock sample. In embodiments, the property of organic material in the rock sample can be a property of kerogen in the rock sample, or a property of asphaltenes or bitumen in the rock sample.

Abstract: A method of rock typing includes obtaining mercury injection capillary pressure (MICP) data regarding a region of interest. A distance matrix is computed for distributions determined from the MICP data using a statistical distance metric. A cluster tree of the distributions is generated using the distance matrix. The cluster tree is adjusted based on a petrographic characteristic to produce an adjusted cluster tree, which is used to determine a pore structure types of the region of interest.

Abstract: An example CO2 monitoring systems is configured for monitoring levels of CO2 in a wellbore. A CO2 monitoring system may include one or more laser monitoring tools. A laser monitoring tool may include an optical element to output a laser beam, a detector to receive the laser beam, a first chamber housing the optical element and detector, and a second chamber including an inlet and an outlet receive and release, respectively, wellbore fluid. The first chamber may be in fluid connection with second chamber via a gas permeable membrane. Gas may permeate from second chamber into first chamber. Gas in the first chamber is subjected to a laser beam. Absorption of light by the gas is measured, and content of gas is determined based at least in part on the amount of light absorption by the gas.

Abstract: Provided are systems and methods for shifting core data to account for flaws that include segmenting core data into multiple contiguous core segments defined by breaking points and iteratively assessing and shifting the segments in sequence (from the deepest segment to the shallowest segment) to align the core data of the contiguous core segments with corresponding segments of log data. For each shift of an assessed segment by a given distance the shallower segments of core data are shifted by the given distance. The breaking points used to define contiguous core segments are identified based on image processing of an image of the core, including identification and comparison of Haralick textual feature parameters across different portions of the core image.
