Abstract: Systems and methods described herein provide for the estimation of the maximum reservoir pressure at which fluid can be injected into a reservoir before causing conductivity increase due to fracture/fault reactivation. An exemplary method includes computing the maximum reservoir pressure for the location of interest prior to fracture/fault reactivation at a given depleted reservoir pressure based on a computed probability of non-exceedance for a field or laboratory estimate of the maximum reservoir pressure prior to fracture/fault reactivation and a computed pressure distribution including a range of potential maximum reservoir pressures for the location of interest prior to fracture/fault reactivation at the given depleted reservoir pressure. The method also includes outputting the computed maximum reservoir pressure as the estimated maximum reservoir pressure for performing a fluid injection operation for the location of interest.

Abstract: Selective removal of non-aromatic hydrocarbons from a xylene isomerization process for para-xylene production is accomplished using a membrane unit positioned within a xylene recovery loop. The membrane unit may include a one-stage or multi-stage (e.g., two-stage) membrane system and may be configured to separate a membrane unit product stream from a non-aromatics rich stream, which can be removed from the xylene recovery loop. The membrane unit may have a xylene permeance of about 60 gm/m2/hr/psi and a xylene to non-aromatic permeance ratio of about 15.

Abstract: A method of detecting and mitigating flow instabilities, such as slugging, in hydrocarbon production wells. Real-time production data pertaining to each well is are retrieved. Using the production data, patterns of flow instability are identified therein. A numerical model of transient and thermal multiphase flow in each well is generated. Well test data is are retrieved from a database. The numerical model is calibrated using the well test data. Using the calibrated numerical model, a parametric study is performed to determine how input parameters affect at least one of stability and performance of the wells. Results of the parametric study are queried to determine a type of flow instability and to determine operating conditions to improve performance of the wells. An advisory is provided to a user to change operating conditions of one or more of the wells, to improve stability and/or performance of one or more of the wells.

Abstract: Systems and methods are provided for improving the operation of groups of reverse flow reactors by operating reactors in a regeneration portion of the reaction cycle to have improved flue gas management. The flue gas from reactor(s) at a later portion of the regeneration step can be selectively used for recycle back to the reactors as a diluent/heat transport fluid. The flue gas from a reactor earlier in a regeneration step can be preferentially used as the gas vented from the system to maintain the desired volume of gas within the system. This results in preferential use of higher temperature flue gas for recycle and lower temperature flue gas for venting from the system. This improved use of flue gas within a reaction system including reverse flow reactors can allow for improved reaction performance while reducing or minimizing heat losses during the regeneration portion of the reaction cycle.

Abstract: Methods and systems for hydrodeoxygenating a bio-derived feedstock during the production of renewable diesel and generating renewable power as part of the hydrodeoxygenation (HDO) process are provided herein. One method includes providing an HDO catalyst within either a shell or tube side of an isothermal HDO reactor including a shell-and-tube configuration and exposing a bio-derived feedstock to the HDO catalyst within the isothermal HDO reactor to form an HDO reactor effluent. The method also includes flowing a water stream through the opposite side of the isothermal HDO reactor as compared to the side including the HDO catalyst to remove the heat of reaction between the bio-derived feedstock and the HDO catalyst, where the removal of the heat of reaction using the water stream forms steam. The method further includes flowing the steam through a steam turbine to provide for the generation of renewable power.

Abstract: Techniques described herein relate to a method for identifying downhole conditions during a drilling operation using a vibratory separator. The method includes calibrating a sensor system attached to the vibratory separator by periodically measuring the G-force acting on the vibratory separator functioning under steady-state operating parameters. The method also includes determining the relationship between the G-force acting on the vibratory separator and the flow rate and rate of penetration (ROP) for the drilling operation by measuring the G-force acting on the vibratory separator functioning under different non-steady-state operating parameters. The method further includes determining an expected total basket weight for each G-force measurement using the G-force/flow rate/ROP relationship, monitoring a current total basket weight of the vibratory separator functioning under current operating parameters, and identifying a downhole condition if the current total basket weight is greater or less than the expected total basket weight for the current operating parameters.

Abstract: Methods disclosed herein include using additive manufacturing to create a joint between a first metallic material and a second metallic material that is different from the first metallic material, wherein the porosity of the joint is less than about 0.1 percent by volume measured according to ASTM B-962. The additive manufacturing can be performed such that no intermetallic brittle phase forms between the first metallic material and the second metallic material.
