摘要： In a formation pressure tester tool, an elongated filter piston possibly having a tapered or sharp edge configured to penetrate mud cake while the probe is being set. At the end of the setting sequence, the filter piston is retracted, thus opening a flowpath from the formation, through the mudcake, to the probe.

摘要： Downhole tools and methods are provided for injecting fluid into a formation. A downhole tool may include a first chamber of injection fluid separated from a second chamber of working fluid by a piston. The working fluid may be employed to apply pressure to the piston to direct injection fluid from the first chamber to the formation. A flow regulator may regulate flow of the injection fluid from the first chamber to the formation.

摘要： A mechanism minimizes the management issues of the participant objects of the logical target set, such as an application set. The mechanism maps the current physical implementation. The mechanism then identifies the target and extraneous object set locations to facilitate isolation. Thereafter, the mechanism optimizes the logical target set placement for best manageability and performance. The mechanism minimizes the management issues by providing a small application footprint. This is accomplished by placing the object set on the fewest necessary volumes to facilitate both application performance and independence of administrative action.
