    Abstract: A fluid (30) of optically clear composition is used to create a viewing window within a wellbore (1), pipelines, tanks, vessels, or any other similar environment. Selective placement of optically clear fluid facilitates acquisition of visual images and/or other data in particular areas of interest within environments containing opaque or non-transparent fluids. Such optically clear fluid can displace opaque fluids and gases, while maintaining specific viscosity, weight, and other fluid properties in order to keep opaque fluids from encroaching into a viewing area while visual data acquisition is performed.

    Abstract: A method and system for detecting the presence of a blockage within a subsea pipe segment includes a submersible and remotely-operated vehicle having a laser emitting element and a hydrophone. The vehicle is positioned proximal to a subsea pipe segment of interest, and the laser emitting element is activated to irradiate a laser target on an exterior portion of the pipe segment. The laser light is converted to heat energy, and heat is conducted from the laser target across the pipe wall to a portion of the bore of the pipe segment. Acoustic signals are produced as a result, of one of the disassociation of gas from a portion of the solid deposit proximal to the laser target, stress cracks induced in the solid deposit and physical changes of state and physical displacement occurring within the blockage. The acoustic signals are detected by the hydrophone on the vehicle.

    Abstract: Adapters for inclusion on the lower end of a completion/work-over riser includes a flow loop in fluid communication with a production flow loop hub and a production bore to facilitate testing and calibration of a subsea multi-phase flow meter during completion operations. The flow loop can be in fluid communication with one or more flow loop isolation valves, one or more production bore isolation valves, one or more annulus bore isolation valves, or one or more cross-over valves. In addition, a pressure/temperature sensor can also be included in the adapter. The adapters disclosed herein permit production fluid to flow through the subsea multi-phase flow meter while the riser is still attached to the subsea Christmas tree and before production operations have begun.
