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: 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.

Abstract: Systems and methods are provided for conversion of methane and/or other hydrocarbons to hydrogen by pyrolysis while reducing or minimizing production of carbon oxides. The heating of the pyrolysis environment can be performed at least in part by using electrical heating within a first stage to heat the coke particles to a desired pyrolysis temperature. This electrical heating can be performed in a hydrogen-rich environment in order to reduce, minimize, or eliminate formation of coke on the surfaces of the electrical heater. The heated coke particles can then be transferred to a second stage for contact with a methane-containing feed, such as a natural gas feed. Depending on the configuration, pyrolysis of methane can potentially occur in both the first stage and second stage. In some aspects, the hydrogen-rich environment in the first stage is formed by passing the partially converted effluent from the second stage into the first stage. In such aspects, the partially converted effluent from the second stage can have an H2 content of 60 vol % or more, or 70 vol % or more, or 80 vol % or more, such as up to 99 vol % or possibly still higher.
