Abstract: A monitoring system includes a spectroscopic probe in fluid connection with a fracturing fluid, reference spectra obtained from one or more fracturing fluid components, and a computer in communication with the spectroscopic probe. The computer includes a predictive model generated from the reference spectra. The computer also includes instructions to compare spectroscopic data obtained from the spectroscopic probe with the predictive model. A modified well fracturing system includes a monitoring system located at a surface location of a hydrocarbon-bearing reservoir and a surface pump in fluid connection with the fracturing fluid source and a wellbore of the hydrocarbon-bearing reservoir. A method for monitoring a fracturing fluid is also described.

Abstract: The disclosure relates to systems and methods to photolytically cleave hydrogen sulfide (H2S) present in a gas mixture produced by a hydrocarbon producing well and/or a gas treatment unit, thereby converting the hydrogen sulfide to hydrogen gas (H2) and a sulfur species (e.g., elemental sulfur, polysulfides, and/or organosulfur compounds). This reduces the amount of hydrogen sulfide present in the gas mixture. The systems and methods can be implemented in a component of a hydrocarbon producing well (e.g., a wellhead, a flow line, a production casing, a production tubing), a component used to transport the gas mixture produced by the well (e.g., a transportation pipeline, an inlet to a gas-oil separation plant), and/or a gas treatment unit (e.g., a tail gas treatment unit). The gas mixture is disposed in an annular space of the component(s), and an ultraviolet (UV) light source delivers UV light to the gas mixture to photolytically cleave the hydrogen sulfide.

Abstract: The disclosure relates to methods of irradiating a gas containing hydrogen sulfide (H2S) with high energy light to photolytically cleave some of the hydrogen sulfide in the gas to form sulfur-containing reactive species. The sulfur-containing reactive species act as autocatalysts that react with some of the remaining hydrogen sulfide in the gas to generate hydrogen gas and one or more sulfur-containing products. The methods remove hydrogen sulfide from the gas and produce hydrogen gas. The methods can be implemented in a component of a hydrocarbon producing well (e.g., a wellhead, a flow line, a production casing, a production tubing), a component used to transport the gas mixture produced by the well (e.g., a transportation pipeline), a gas treatment system (e.g., a tail gas treatment system), a borehole and/or an underground formation.

Abstract: A method of electrochemically treating a hydrocarbon-bearing formation is provided. The method includes electrochemically treating an aqueous fluid to provide a first fluid having a first electrochemical potential and a second fluid having a second electrochemical potential. The first electrochemical potential the second electrochemical potential have opposite signs. The method then includes introducing an amount of the first fluid into the hydrocarbon bearing formation, and then an amount of a spacer fluid is introduced into the hydrocarbon-bearing formation. An amount of the second fluid may be optionally introduced into the formation. The steps of introducing the fluids are repeated until an end point is reached. A system for electrochemically a hydrocarbon-bearing formation is also provided.

Abstract: Methods of evaluating a surfactant may include ultrasonicating a mixture of oil, water, and the surfactant to form at least one of the following: a sub-macroemulsion, a macroemulsion phase or a combination of the aforementioned; separating the sub-macroemulsion from the macroemulsion phase; introducing the sub-macroemulsion into a foam container; performing a first automated phase identification of the sub-macroemulsion; introducing a gas into the sub-macroemulsion to generate a column of foam, where the column of foam has a height in the foam container; performing a second automated phase identification of the sub-macroemulsion; and measuring the height of the column of foam in the foam container. In these methods, the first and second automated phase identifications may be configured to quantify one or more liquid phases and a foam phase in the column.

Abstract: Methods are disclosed for synthesizing ionic liquid formulations using non-stoichiometric hydrophobic or hydrotropic ionic liquids, including aprotic or protic ionic liquids, to create emulsions, microemulsions, or nanoemulsions. Additionally, the provided ionic liquid formulations may be used to make surfactant-free or detergentless microemulsions or nanoemulsions that may be used as additives for aqueous or oil-based solutions. Methods for introducing an ionic liquid in an injection fluid into a reservoir via an introduction well area also provided. The injection fluid intermingles with reservoir fluid and the intermingled injection fluid and reservoir fluid is retrieved via a production well. Methods for introducing an ionic liquid in an injection fluid may be used for CO2 sequestration within a reservoir. The CO2 may be introduced concurrently or by alternating injections of CO2.

Abstract: A method includes introducing a drill string including a bottom hole assembly into a wellbore, wherein the bottom hole assembly includes a mounted 3D printing sub-assembly. A wellbore is drilled with the bottom hole assembly, and at least a portion of a casing is printed with the 3D printing sub-assembly while drilling the wellbore. A related system includes a drill string having a length of drill pipe and a bottom hole assembly disposed at a distal end of the length of drill pipe. A 3D printing sub-assembly is mounted on the bottom hole assembly, wherein the printing sub-assembly includes a printer housing and a 3D printing head mounted at the printer housing. A control guides the 3D printing head to print at least a portion of a casing at a location radially away from the central longitudinal axis of the drill string.
