Abstract: Methods for identifying hydrocarbon contamination sources may include fingerprinting hydrocarbons using isotopocule analyses for BTEX compounds. For example, methods for identifying hydrocarbon contamination sources may comprise: extracting BTEX compounds from a sample; measuring the isotopocule composition of the BTEX compounds; and determining a characteristic of the sample based on the isotopocule composition. Such characteristics may include, but are not limited to, the characteristic of the sample comprises one or more selected from the group consisting of: a source of the sample, a condition at which the sample formed or was last equilibrated, a migration time from a source to a sample location, weathering of the sample, and degree to which the sample is anthropogenic and naturally-occurring.

Abstract: A slurry including a density-tunable heavy fracturing fluid and a method for completing a hydrocarbon well using such a slurry are provided herein. The slurry includes a proppant and the density-tunable heavy fracturing fluid, where the density-tunable heavy fracturing fluid includes a pseudo heavy fluid suspension, a concentrated aqueous solution of a soluble heavy compound, and/or a high-density organic solution. The density of the density-tunable heavy fracturing fluid is between 1.25 grams/milliliter (g/ml) and 3.4 g/ml. Moreover, the density of the density-tunable heavy fracturing fluid is selected based on the density of the proppant. According to the method provided herein, the slurry is used to provide for more effective placement of the proppant within the fractures than can be achieved using only a slurry including conventional fracturing fluid and the proppant.

Abstract: Provided herein are methods of novel methods of synthesizing a metal-organic framework system by vapor-phase appending of a plurality of ligands appended to a metal-organic framework. Also, provided are methods of recycling metal-organic framework systems by detaching the ligand and re-appending the same ligand or appending a different ligand to the metal-organic framework to provide a recycled or repurposed metal-organic framework system.

Abstract: A methodology for modeling multi-well communication considering multiple flow regimes for hydrocarbon management is disclosed. Understanding well communication scenarios in unconventional reservoirs may assist in assessing hydrocarbon asset development planning. Typically, well communication is determined by using a suitably-designed interference test, wherein the observation well is kept closed and the choke of a neighboring signal well is manipulated, with the resulting deviation in the pressure trend being used to determine the well communication. The interference test is not suitable due to requiring wells to be closed and to being applicable to only certain types of wells. Thus, a producer-producer connectivity model is used to analyze well communication and to quantify well communication strength. Such as connectivity model may use production data (not requiring wells be kept closed), does not require the building of a reservoir model, and may consider the simultaneous interaction amongst multiple wells through time.

Abstract: A method includes containing an algae media within a contactor, introducing a stream of natural gas comprising up to 80 wt % carbon dioxide (CO2) into the contactor, contacting the natural gas on the algae media and thereby allowing the algae media to consume CO2 from the natural gas, and discharging a stream of natural gas comprising 2 wt % or less CO2 from the contactor.

Abstract: Systems and methods are provided for performing hydrodeoxygenation of bio-derived feeds while maintaining the hydrodeoxygenation catalyst in a sulfided state. During hydrodeoxygenation, a hydrogen-containing stream is provided to the hydrodeoxygenation reactor as a hydrogen treat gas to provide hydrogen for the reaction. In some aspects, the hydrogen treat gas used for hydrodeoxygenation can be formed at least in part from hydrogen that has been used as a stripping gas for removing H2S from a rich amine stream. In other aspects, H2S can be stripped using water vapor, and a resulting overhead HS stream can be compressed prior to incorporation of the H2S into a hydrogen-containing stream. The resulting hydrogen-containing stream can include sufficient H2S to substantially maintain the catalyst in the hydrodeoxygenation stage in a sulfided state.

Abstract: Pitch compositions suitable for spinning may comprise: a pitch having a softening point (SP) below 400° C. and is capable of achieving a radial Hencky strain prior to break of about 0.7 to about 10, at spinning temperature (Ts) ranging from about SP−30° C. to about SP+80° C. Methods for producing a carbon fiber from a pitch composition at a temperature within a spinning temperature (Ts) range may comprise determining a temperature range wherein the maximum radial Hencky strain (εR) lies above a minimum process radial Hencky strain, and wherein the minimum process radial Hencky strain is within a range of about 0.7 to about 10. The spinning temperature (Ts) range may be determined by measuring a maximum radial Hencky strain (εR) prior to break at a series of different temperatures and strain rates. Carbon fiber composites may comprise of the said carbon fiber.

Abstract: Methods of stimulating a hydrocarbon well are disclosed herein. The hydrocarbon well includes a wellbore that extends within a subterranean formation and a tubular that extends within the wellbore and defines a tubular conduit. The methods include retaining a sealing structure within the tubular conduit and, during the retaining, stimulating a zone of the subterranean formation. Subsequent to the stimulating, the methods include fluidly isolating the zone of the subterranean formation from the uphole region by at least partially sealing the plurality of perforations. Subsequent to the fluidly isolating, the methods include moving the sealing structure in a downhole direction within the tubular conduit. The methods also include repeating the retaining, the stimulating, the fluidly isolating, and the moving a plurality of times to stimulate a plurality of corresponding zones of the subterranean formation.
