Abstract: A method involves mixing metallic particles and a liquefied polymer to form a mixture, placing the mixture within a mold, placing a magnet in the vicinity of the mixture within the mold, thereby causing the metallic particles to position themselves in a self-assembly formation within the mixture in response to a magnetic field generated by the magnet, and solidifying the liquefied polymer, such that a polymer matrix is formed. The metallic particles are distributed and secured in the self-assembly formation throughout the polymer matrix, thereby forming a ballast for an untethered downhole tool configured to be lowered into a well formed in a subterranean formation. The polymer matrix is configured to dissolve in response to being exposed to downhole fluid within the well at specified downhole conditions.

Abstract: Well treatment fluids may include solid particles comprising one or more components selected from the group consisting of urea, ammonium nitrate, ammonium chloride, barium hydroxide, and ammonium thiocyanate. These well treatment fluids may also include a carrier fluid, which may be an aqueous polymeric fluid, an oil, or combinations thereof. The aqueous polymeric fluid may include a polymer selected from the group consisting of guar gum, hydroxypropyl guar, carboxymethyl hydroxypropyl guar, cellulose, or polyacrylamide. The oil may include a material selected from the group consisting of diesel, mineral oil, and wax. Methods for reducing an acid carbonate reaction in a carbonate formation may include pumping a composition of solid particles into a formation; releasing the solid particles from the capsules or emulsion within the formation; and injecting an acid following the releasing step or during pumping, wherein the acid carbonate reaction is carried out at a reduced reaction rate.

Abstract: A method of estimating dissolution progress of a salt in construction of a salt cavern includes: defining, for each of a plurality of parameters, an operable range of respective parameter and an average value of the operable range of respective parameter; performing a plurality of flooding tests, by varying one particular parameter among the plurality of parameters from a lowest value to a highest value in the operable range of the one particular parameter and keeping all other parameters at the average value of respective parameter; and obtaining an analytical relationship of a mass of dissolved salt versus the one particular parameter.

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: Method and systems for generating a reservoir simulation grid for a subterranean reservoir are disclosed. The method may include, using a reservoir simulation system, to obtain a reservoir model, where the reservoir model comprises a plurality of wellbore trajectories, define a coarse simulation grid pertaining to, at least a portion, of the reservoir model, and determine a grid refinement field based, at least in part, on the reservoir model. The method may further include, using a reservoir simulation system, to form a tree based on the coarse simulation grid, refine the tree at least in part, on an intersection of the grid refinement field and the coarse simulation grid, and define the reservoir simulation grid based, at least in part, on the refined tree and the coarse simulation grid.

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.

Abstract: A method for generating a multi-component surrogate is provided. The method includes determining, based on a detailed hydrocarbon analysis, components of a physical fuel sample, selecting, for a hydrocarbon, chemicals from a list of known chemicals in a chemical property database, chemical property correlation software, or chemical process software package, the hydrocarbon having an equivalent molecular structure as each of the chemicals, dividing a concentration of the hydrocarbon in the physical fuel sample into surrogate concentrations corresponding to the chemicals, and generating the multi-component surrogate based at least on the surrogate concentrations, where each of the chemicals represents the hydrocarbon as a surrogate in the multi-component surrogate, and the multi-component surrogate is used to represent the physical fuel sample in a one-dimensional (1D) hydraulic modeling software to model a direct injection (DI) system.
