Abstract: This invention describes ways of obtaining nano-particulated adjuvants formed by different synthetic variants of GM3 ganglioside. Depending on the fine structure of the fatty acid in the ceramide of the synthetic GM3, said adjuvants are able to stimulate specifically and in a specialized way the humoral or cellular immune response against accompanying antigens. Particularly, this invention provides immunogenic vaccine compositions that comprise peptides, polypeptides or proteins and the aforementioned nanoparticles, which are formed through the dispersion of hydrophobic proteins of the outer membrane complex (OMC) of Neisseria meningitidis in solutions containing fully synthetic variants of the GM3 ganglioside.

Abstract: A bi-directional telemetry system for use in a wellbore environment is provided. The bi-directional telemetry system includes a first acoustic telemetry component and a second acoustic telemetry component that is separate from the first acoustic telemetry component. The first acoustic telemetry component comprises a downhole acoustic transmitter disposed in a wellbore and operable to transmit the first acoustic signal and an uphole acoustic receiver. The second acoustic telemetry component comprises an uphole acoustic transmitter operable to transmit the second acoustic signal and a downhole acoustic receiver.

Abstract: An acoustic receiver is provided. The acoustic receiver includes an optical vibrometer having an optical emitter and an optical receiver. The optical receiver is operable to emit an optical beam to a single point of reference on a conduit, and the optical receiver is operable to receive one or more reflections of the optical beam off of the single point of reference on the conduit, thereby detecting waves propagating through the conduit created by an acoustic transmitter. A processor is coupled with the optical emitter and the optical receiver. The processor is operable to: determine components of the waves created by the acoustic transmitter based on the one or more reflections of the optical beam; and determine a signal transmitted from the acoustic transmitter based on the components of the waves.

A method of performing a borehole operation may comprise disposing a coiled tubing string into a borehole and wherein a fiber optic cable is strain-coupled to the coiled tubing string, and measuring at least one property of the borehole with the fiber optic cable.

Abstract: Hydrajetting assemblies provide data communication and the ability to jet abrasive fluid at pumping rates exceeding the abrasiveness rating of downhole devices. A hydrajetting tool includes jetting nozzles to jet a fluid into a subterranean formation. A capillary to house a data communication line is positioned along the housing of the tool. The communication line in run through the capillary and couples to a downflow sensing device having a fluid flow prevention device thereon. During perforating, the fluid flow device is closed, thus causing the pressurized abrasive fluid to jet out the nozzles. Since the sensing device is positioned downflow of the hydrajetting tool, the abrasive fluid may be pumped at a rate exceeding the abrasiveness rating of the sensing device. Also, real-time data may be communicated from the sensing device using the communication line.
