摘要： A system for carbon dioxide (CO2) capture at a wellhead using a mixed matrix membranes (MMM). The MMM includes a polymer matrix and covalent triazine framework (CTF) fillers. The captured CO2 stream may be reutilized through sequestration and utilization approaches. The bulk stream may be split into multiple streams for various applications. Some CO2 may be converted chemically into fuels, reaction intermediates, and productivity enhancement tools such as methanol, syngas, CO2-foam, used in fracking fluids, and stimulant acids. The rest may be stored through direct injection into porous formations or reactive rocks such as basalt.

摘要： A pressure exchanger includes a rotor configured to receive first fluid, receive second fluid, and exchange pressure between the first fluid and the second fluid. The pressure exchanger further includes a first component forming a low-pressure port, wherein the first fluid is routed between the rotor and the low-pressure port via a low-pressure passageway. The pressure exchanger further includes a second component forming a fluid passageway between the low-pressure passageway and a centerbore of the pressure exchanger.

摘要： A process for manufacturing particles including a stereocomplex of poly-D-lactide (PDLA) and poly-L-lactide (PLLA), including the steps of: extruding a melt including 30-70 wt. % of PDLA and 70-30 wt. % of PLLA through an sc-PLA formation zone in a twin-screw extruder, wherein the formation zone is operated at a barrel temperature above the melting temperature of the PDLA and PLLA and below 220° C.; wherein the sc-PLA formation zone is followed by a finishing zone which is operated at a barrel temperature below 160° C.; wherein the finishing zone is followed by the end of the extruder which has a die-head resistance of 0; and recovering solid stereocomplex particles from the end of the extruder. The stereocomplex particles find use in various applications, e.g., in fracking fluids, as filler, as nucleating agent, in particular in the molding of semi-crystalline PLA, or as a starting material for the manufacture of sc-PLA products.

摘要： Embodiments relate to a hydraulic fracturing system that includes a blender unit. The system includes an auger and hopper assembly to receive proppant from a proppant source and feed the proppant to the blender unit for mixing with a fluid. A first power source is used to power the blender unit in order to mix the proppant with the fluid and prepare a fracturing slurry. A second power source independently powers the auger and hopper assembly in order to align the hopper of the auger and hopper assembly with a proppant feed from the proppant source. Thus, the auger and hopper assembly can be stowed or deployed without use of the first power source, which is the main power supply to the blender unit.

摘要： A method for evaluating induced fractures in a wellbore includes obtaining a first set of data in a wellbore using a downhole tool. The method also includes pumping a first proppant into the wellbore after the first set of data is obtained. The first proppant includes a first tracer that is not radioactive. The method also includes pumping a second proppant into the wellbore. The second proppant includes a second tracer that is not radioactive. The second tracer is different than the first tracer. The first proppant and the second proppant flow into fractures in the wellbore. The method also includes obtaining a second set of data in the wellbore using the downhole tool after the first and second proppants are pumped into the wellbore. The method also includes comparing the first and second sets of data.

摘要： A method for monitoring gas production in a subterranean formation includes introducing a polymer composite particle having a degradable portion and a non-degradable portion including a tracer into a stimulation fluid and injecting the stimulation fluid into the subterranean formation to a treatment stage of a treatment zone. The treatment stage has at least one opening that the polymer composite particle may flow into and remain inside. The polymer composite particle may be exposed to moisture at a downhole temperature while inside the at least one opening. The moisture may degrade the degradable portion of the polymer composite particle, thereby releasing the non-degradable portion including the tracer. Produced gas that includes the non-degradable portion including the tracer may be recovered from the subterranean formation and the tracer may be correlated to the treatment stage of the treatment zone of the subterranean formation.

摘要： A wellbore system for perforating a subterranean formation including a dissolvable perforating gun that may be wirelessly operated to fire at a predetermined wellbore location and thereafter fragmented and dissolved with wellbore fluids. The perforating gun may take the form of a strip gun with an elongated rod or other charge holder carrying a plurality of exposed perforating charges thereon. The exposed shaped charges may each be equipped with an individual charge cover or filler material disposed over a liner that forms a jet when the shaped charge is detonated. A wiper to facilitate pumping the perforating gun through the wellbore and may include an initiator for detecting a signal or condition indicative of the perforating gun having reached a predetermined location to cause the perforating gun to fire.

摘要： A hydraulic fracturing operation is performed in a wellbore formed in a subterranean zone. A wellhead is installed at an entrance to the wellbore. Liquid CO2 is flowed through a pipeline located at a surface and fluidically coupled to the wellhead. The liquid CO2 is flowed into the wellbore through the wellhead to perform the hydraulic fracturing. The hydraulic fracturing operation including flowing of the liquid CO2 through the pipeline to the wellhead is stopped. A portion of the liquid CO2 is withdrawn from within the pipeline into a liquid CO2 storage container, which is a portable system designed to capture and store liquid CO2 and that is fluidically coupled to the pipeline at the surface.
