Abstract: Methods of repairing a flexible pipe include securing a composite tape to a surface of an outer sheath using a structural adhesive, the composite tape forming a composite repair over a rupture in the outer sheath; and immobilizing the composite tape at the ends of the wrapped portion with a securing device. Methods of repairing a flexible pipe include applying a structural adhesive to a composite tape; and securing to composite tape to an outer sheath of the flexible pipe, the composite tape forming a composite repair over a rupture in the outer sheath. Systems include a flexible pipe; a composite repair sealing a rupture in an outer sheath of the flexible pipe, the composite repair including a composite tape wrapped helically around the flexible pipe, and a structural adhesive securing the composite tape to the flexible pipe.

Abstract: Systems and methods are provided for operating molten carbonate fuel cells to produce increased amounts of H2 in the anode effluent while still maintaining operation of the cell within conventional operation boundaries, such as having a temperature differential between the cathode input flow and the cathode effluent of 35° C. or more, with the cathode effluent being hotter than the cathode input flow. This temperature differential between the cathode input flow and the cathode effluent while still producing excess hydrogen is achieved in part by a) passing an input flow containing hydrocarbons and/or reformable fuel into an external reformer, b) reforming 20 vol % or more of the hydrocarbons and/or reformable fuel in the external reformer prior to c) passing the partially reformed input flow into a fuel cell or fuel cell stack where additional reforming is performed in the anode(s) and/or in a reforming element in the fuel cell stack.

Abstract: Systems and methods are provided for forming soft asphalt compositions with improved properties that are derived from distillation of a crude oil (or mixture of crude oils) having an API gravity of 24° or less. In order to form a target asphalt composition from a feedstock having an API gravity of 24° or less, a distillation is performed where at least two fractions are generated that have a T10 distillation point of 430° C. or more. A first fraction can correspond to a distillate fraction having a T10 distillation 2021em165-usoint of 430° C. or more. A second fraction can correspond to a bottoms fraction. Disproportionate blending can then be used to combine a portion of the first fraction with a portion of the second fraction. By using disproportionate blending of a distillate fraction and a bottoms fraction, an asphalt product fraction can be formed that has both a flash point of 270° C. or more and a KV100 between roughly 700 cSt and 1200 cSt.

Abstract: A method for controlling the growth of a hydraulic fracture using a stress shadow generated during a hydraulic fracturing operation includes selecting a stage pair including a first stage and a second stage for which hydraulic fractures are to be generated via a hydraulic fracturing operation. The method also includes hydraulic fracturing the first stage to generate a corresponding first hydraulic fracture and controlling a magnitude of a stress shadow originating from the first hydraulic fracture by varying at least one parameter of the hydraulic fracturing operation, where the stress shadow is controlled so as to provide a second hydraulic fracture of a target fracture shape for the second stage. The method further includes hydraulic fracturing the second stage to generate the second hydraulic fracture with the target fracture shape.

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 for producing a blended jet boiling range composition stream may include: oligomerizing an ethylene stream to a C4+ olefin stream in a first olefin oligomerization unit, wherein the C4+ olefin stream contains no greater than 10 wt % of methane, ethylene, and ethane combined; wherein the ethylene stream contains at least 50 wt % ethylene, at least 2000 wppm ethane, no greater than 1000 wppm of methane, and no greater than 20 wppm each of carbon monoxide and hydrogen; oligomerizing the C4+ olefin stream and a propylene/C4+ olefin stream in a second oligomerization unit to produce an isoolefinic stream; subjecting at least a portion of the isoolefinic stream to a hydroprocessing process with hydrogen as treat gas to produce an isoparaffinic stream having no greater than 10 wt % olefin content; and using least a portion of the isoparaffinic stream to create the blended jet boiling range.

Abstract: Systems and methods are provided for using molten carbonate fuel cells (MCFCs) to reduce, minimize, and/or avoid CO2 emissions in a marine vessel environment. The systems and methods can include operation of MCFCs on a marine vessel under high fuel utilization conditions in order to provide power and capture CO2. The high fuel utilization conditions can allow for mitigation of CO2 over extended periods of time in spite of the challenges of performing CO2 mitigation in a potentially isolated environment such as a marine vessel. Additionally, the high fuel utilization can also reduce or minimize exhaust of fuels, such as methane, to the environment.

Abstract: A plunger lift system, as well as a method for monitoring plunger parameters within a wellbore using such a plunger lift system, are provided. The plunger lift system includes a lubricator attached to a wellhead at the surface and a plunger dimensioned to travel through the production tubing upon being released from the lubricator. The plunger lift system also includes magnetic sensor systems installed along the production tubing, where each magnetic sensor system includes a magnetic sensor for detecting the passage of the plunger as it travels through the production tubing, as well a communication device for transmitting communication signals between the magnetic sensor systems and a computing system located at the surface, where the computing system includes a processor and a non-transitory, computer-readable storage medium including computer-executable instructions that direct the processor to dynamically determine the plunger position and/or velocity based on the received communication signals.
