摘要： A technique improves the formation of dependable seals along wellbores. A packer is constructed with a plurality of elastomeric layers and an internal mechanical layer that extend between mechanical extremities. One or more of a variety of features can be added to, or used in conjunction with, the packer to reduce wear and the potential for detrimental damage during use of the packer.

摘要： A technique involves sampling fluids in a well environment. An expandable packer is constructed with an outer seal layer. At least one sample drain is positioned through the outer seal layer, and a heater element is deployed in the at least one sample drain. In one embodiment, the heater element is deployed proximate a radially outlying surface of the expandable packer. Additionally, a temperature sensor may be positioned proximate the at least one sample drain to monitor temperature in the environment heated by the heater element.

摘要： An apparatus includes a base pipe and a fluid control material. The base pipe includes openings, and the fluid control material is mounted to the pipe to control fluid communication through the openings of the pipe. The fluid control material has a permeability that may be changed to selectively control the communication of well fluid through the openings.

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. A mandrel is positioned within the outer flexible skin, and an expansion mechanism is provided to control expansion of the outer flexible skin to selectively create sealing engagement with a surrounding wall.

摘要： A sampling assembly of a single packer assembly may have more guard drains than sampling drains. The single packer assembly having the sampling assembly may be deployed in a wellbore formed in a subterranean formation, and the single packer assembly may be deployed on a wireline cable or another deployment or conveyance. The number and the area of the sampling drains, the number and the area of the guard drains, and the positions of the sampling drains and the guard drains may be designed so that the guard drains which are operational may provide a fluid intake rate exceeding a predetermined threshold if one of the guard drains is congested and/or blocked.

摘要： A technique involves collecting formation fluids through a single packer having a plurality of sample collectors disposed along an expandable packer element. An anti-expansion device also is deployed along the expandable packer element to limit expansion in localized regions. Limiting the expansion can provide additional space or an increased production surface that facilitates collection of samples.

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 layer that expands to create a seal with a surrounding wellbore wall. The drain is located in the outer layer between its axial ends for collecting formation fluid which is routed from the drain to an axial end of the outer layer via a fluid flow passage. Mechanical fittings are mounted at the axial ends of the outer layer, and at least one of the mechanical fittings comprises one or more flow members coupled to the flow passage to direct the collected fluid from the packer. The one or more flow members are designed to move in a manner that freely allows radial expansion and contraction of the outer layer.

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.
