摘要： A technique involves collecting formation fluids through a single packer having at least one drain located within the single packer. The single packer is designed with an outer structural layer that expands across an expansion zone to facilitate creation of a seal with a surrounding wellbore wall. An inflatable bladder can be used within the outer structural layer to cause expansion, and a seal can be disposed for cooperation with the outer structural layer to facilitate sealing engagement with the surrounding wellbore wall. One or more drain features are used to improve the sampling process and/or to facilitate flow through the drain over the life of the single packer.

摘要： A technique involves collecting formation fluids through a single packer having at least one drain located within the single packer. The single packer is designed with an outer flexible skin and one or more drains coupled to the outer flexible skin. The single packer further comprises one or more sensors positioned to detect one or more specific parameters that may be related to well characteristics and/or single packer characteristics.

摘要： A technique involves collecting formation fluids through a single packer having at least one drain located within the single packer. The single packer comprises an outer seal layer, and the at least one drain is positioned in the outer seal layer. A viscosity system also is incorporated and enables the viscosity of a surrounding fluid to be selectively lowered for sampling.

摘要： Apparatus and methods to control fluid flow in a downhole tool are disclosed. A disclosed example system includes a hydraulically actuatable device having a cavity for receiving pressurized hydraulic fluid stored by a reservoir, a first and a second hydraulic pump, a motor and means for selectively flowing hydraulic fluid from the outlet of at least one of the first and second pumps to the at least one cavity. The first and second hydraulic pumps include an inlet fluidly coupled to the reservoir and an outlet fluidly coupled to the cavity, and the motor is operatively coupled to at least one of the pumps.
