摘要： Methods and systems are provided to learn and apply a mapping function from data representing concentrations of atomic elements in a geological formation (or other data corresponding thereto) to mineral component concentrations in the geological formation (and/or from mineral component concentrations to reconstructed elemental concentrations in the geological formation). The mapping function can be derived from a trained neural network (such as an autoencoder). The output of the mapping function can be used to determine estimates of one or more formation properties, such as formation matrix density, formation porosity, matrix Sigma, formation saturation, other formation property, or combinations thereof.

摘要： A system and method for determining a net source rock thickness is disclosed. The method includes obtaining at least one well log, a first and second plurality of core samples from a wellbore, and for each of the first plurality determining a relative abundance of inorganic materials, and for each of the second plurality a set of organic material data. The method further includes determining a validated total organic content and a measured source rock thickness based on the organic material data and relative abundance of inorganic materials and determining a data and a prediction portion of the wellbore, based on the second plurality sample locations.

摘要： The systems and methods described in this specification relate to installing a wellbore completion setup of a wellbore based on a probability within a reservoir. The systems and methods measure one or more properties of the formation and receive data representing the one or more measured properties. The systems and methods use the one or more properties as input conditions to a finite element model of the wellbore. The systems and methods solve the finite element model to determine stresses of the formation surrounding the wellbore. The systems and methods determine a size of one or more rock fragments based on whether the determined stresses from the finite element model are greater than a threshold stress of a failure criterion. The systems and methods determine the probability, select the wellbore completion setup of the wellbore based on the bridging probability, and install the selected wellbore completion setup in the wellbore.

摘要： A scratch tester has at least one cutter that moves simultaneously both rotationally and axially relative to the rock it is cutting. When rotational and axial movements are constant, the cutter generates a helical groove in the rock. In borehole embodiments, the scratch tester is fixed at a desired location using centralizers, and the cutter is provided on a motorized platform/track that translates between the centralizers and rotates around a central axis. The cutter faces outward and extends via a cutter arm to engage and carve a helical groove in the borehole wall. A laboratory scratch tester includes a holder for a solid cylindrical core sample and a motorized translating frame on which a cutter extends. The cutter is directed toward the core sample, and the holder with the core sample is rotated by a motor so that as the cutter translates relative thereto, a helical groove is cut thereinto.

摘要： Methods and systems for separating mud from drill cuttings are disclosed. The method includes collecting drill cuttings from a shale shaker or a wellhead, placing the drill cuttings in a fluid that matches the fluid in the drilling mud, and filtering the drill cuttings through a sieve having a first mesh size. The method further includes placing the filtered drill cuttings in a sieve basket having a second mesh size, wherein the second mesh size is smaller than the first mesh size, placing the sieve basket in a vessel, and adding the fluid to completely submerge the drill cuttings in the fluid. The method also includes placing the vessel including the sieve basket, the drill cuttings, and the fluid in a sonicator-shaker, and simultaneously sonicating and shaking the vessel to separate the drill cuttings from contaminants thereon.

摘要： A coreflood experiment may be modeled by generating a three dimensional computer simulation model of a core plug and modeling within the three dimensional computer simulation model one or both of a fluid introduction element or a fluid extraction element of a core holder used in the coreflood experiment. Once generated, the model may be loaded and used when running a simulation to model a heterogeneous distribution of fluid flow proximate one or more faces of the core plug.

摘要： A method for predicting a formation property of a formation, including the steps of: drilling a first well that penetrates the formation, obtaining well properties from the first well, determining a measured formation property from the first well, determining a correlation function that estimates a predicted formation property from the well properties, wherein the correlation function comprises coefficients, calibrating the correlation function by modifying the coefficients until the predicted formation property best matches the measured formation property, drilling a second well that penetrates the formation, obtaining well properties from the second well, determining the formation property from the second well by applying the correlation function with the modified coefficients to the well properties.
