    Abstract: A technique for deploying expandables is provided. The technique comprises actuating an expansion tool such that the expansion tool imparts an outwardly directed radial force on an expandable tubular. More specifically, the expansion tool imparts radial expansion forces against an interior surface of the tubular thereby allowing the tubular to be deployed in a wellbore environment.

    Abstract: A method and system of subsea intervention comprises lowering one or more assemblies of intervention equipment into the sea. Underwater marine units (such as remote operated vehicles or small submarines) may be employed to connect the assemblies to each other and to the subsea wellhead equipment. The subsea wellhead equipment includes a carrier line spool (e.g., coiled tubing spool, wireline spool, slickline spool) and equipment to inject a carrier line from the carrier line spool into the subsea well. The carrier line spool can be located underwater, such as on the sea floor or positioned above the subsea wellhead equipment. The carrier line spool can also be located on a sea vessel. Also, to switch tools, a carousel system having multiple chambers containing different types of tools can be used.

    Abstract: A system and method is provided for utilizing both a wellbore completion and a formation treatment system. The formation treatment system comprises a bypass that directs well treatment fluid around the wellbore completion. The bypass protects the wellbore completion from potentially corrosive or erosive well treatment fluids which, in turn, allows the wellbore completion to remain downhole during the introduction of well treatment fluids.

    Abstract: Methods for determining hydraulic properties of a formation surrounding a borehole are disclosed. The methods use a borehole tool preferably having a first probe for injecting fluid into a formation or obtaining fluid from the formation, a second probe vertically displaced relative to the first probe, and a third probe azimuthally displaced relative to the first probe. The method generally comprises: varying the pressure at the first probe of the borehole tool; measuring pressures at the second and third probes resulting from the varying of pressure at the first probe; and utilizing the pressures measured at the second and third probes to determine values over time of a function related to the hydraulic properties of the formation. This function is a function of the geometry and rock and fluid properties of the formation but is independent of the manner in which the pressure is varied at the first probe.
