Abstract: A system and method for determining a mud-weight window is disclosed. The method includes determining, for each of a plurality of borehole-formation training models, a fracture mud weight using a first physics-based method and a collapse mud weight using a second physics-based method, and training, using the plurality of borehole-formation training models, an artificial intelligence (AI) network to predict the fracture and collapse mud weights for a borehole formation model. The method further includes determining, using the trained AI network, an AI fracture and an AI collapse mud weight from an observed borehole-formation model, and a search window surrounding each AI mud weight. The method further includes predicting a final fracture mud weight within the fracture search window using the first physics-based method and a final collapse mud weight within the collapse search window using the second physics-based method, and determining the mud-weight window bounded by the two final mud weights.

Abstract: 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.

Abstract: A method for evaluating and controlling a washout region of a wellbore placed in a formation includes: obtaining information about the wellbore and the formation; establishing a washout indicator function as a function of time and location; computationally determining whether the washout region exists by calculating the washout indicator function on a cross section of the wellbore and the formation, at each depth in a specific depth range; and upon finding presence of the washout region in the specific depth range, quantifying the washout region. The washout indicator function returns: a negative value for a point within the formation; a positive value for a point within the washout region; and zero for a point on a boundary.

Abstract: Methods and systems include obtaining a correlation and obtaining a salt sample from a salt formation. The methods and systems further include, for each of N cycles, exposing, using an injection system, the salt sample to an nth amount of a gas and determining an nth value of a property by subjecting the salt sample, using an atomic force microscopy (AFM) system, to an AFM test. The methods and systems further include determining a relationship using the N values of the property, determining, using the correlation, a macroscale relationship based on the relationship, and generating a fit constitutive model by fitting the constitutive model to the macroscale relationship. The methods and systems include generating a model of a salt cavern within the salt formation based on the fit constitutive model and designing a salt cavern for withdrawal cycles of the gas using the model.
