Patent number: 11946370Abstract: Asphaltene onset pressure of a formation fluid is determined by subjecting the fluid to a plurality of tests where depressurization is conducted at a different depressurization rate for each test while optically monitoring the fluid for asphaltene flocculation. The pressures at which asphaltene flocculation are detected in each test are fit to a curve as a function of depressurization rate, and the curve is extrapolated to a pressure (e.g., 0 psi) to provide the asphaltene onset pressure.Type: GrantFiled: March 13, 2023Date of Patent: April 2, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Matthew T.

Patent number: 11698490Abstract: The present disclosure relates to a method of forming a tapered optical fiber, where the optical fiber has a cladding encasing a core and has an initial outer diameter. The method involves applying opposing forces to spaced apart sections of the optical fiber. The spaced apart sections define a length portion representing a waist region. While applying the opposing forces, simultaneously applying heat to the waist region to gradually produce a taper of the optical fiber within the waist region. The taper has a first diameter at a midpoint of the waist region which is less than the initial outer diameter. An etch operation is then performed by chemically etching at least a subportion of the waist region of the optical fiber to reduce the subportion to a second diameter which is less than the first diameter.Type: GrantFiled: August 31, 2021Date of Patent: July 11, 2023Assignee: Lawrence Livermore National Security, LLCInventors: Tiziana C. Bond, Sara Elizabeth Harrison, Catherine E. Reinhardt, Payal Kamlesh Singh, Victor V. Khitrov

Publication number: 20230134697Abstract: A one-piece package or container is disclosed that includes an opening device in conjunction with a self-closing valve for facilitating opening of the package and for dispensing fluids in a controlled manner. In one embodiment, the opening device can include at least one breachable bubble. The at least one breachable bubble can be formed by a seal along a perimeter and/or fluid channel of the package. The package includes a fluid channel with a self-closing valve that can be opened by breaching the breachable bubble. After the package is opened, the self-closing valve prevents fluid from flowing through the fluid channel until pressure is applied to the package, such as pressure through squeezing . Thus, when a user applies pressure to the package, the contents of the package can be dispensed through the fluid channel in a controlled manner.Type: ApplicationFiled: June 10, 2021Publication date: May 4, 2023Inventors: William S.
