Abstract
An arrangement having a body with at least one drain provided in the body is disclosed. The drain is configured to receive fluid when the body is expanded from a first unexpanded condition to a second expanded condition. At least one flowline is connectable to the drain. A screen is positioned over the drain and is configurable to expand from the first unexpanded condition to the second expanded condition.
Claims20
A system comprising:
- a body having a plurality of fluid ports positioned radially about the body, the body expandable or inflatable from a first position to a second position such that a diameter of the body at the first position is less than a diameter of the body at the second position, wherein at least one of the plurality of fluid ports is positioned a radial distance from another one of the plurality of fluid ports;
- a filter positioned about at least one of the plurality of fluid ports to prevent debris from passing into the fluid port.
A system comprising:
- an inflatable packer movable between a first position and a second position, the packer having a greater diameter at the second position than at the first position;
- a first port in the packer providing fluid communication from an exterior of the packer to an interior of the packer;
- a filter at least partially covering an exterior surface of the first port, wherein the filter increases in size as the inflatable packer moves from the first position to the second position.
A method, comprising:
- placing a packer in a downhole environment;
- expanding the packer in the downhole environment so that an exterior surface of the packer contacts an interior diameter of the downhole environment, wherein during the expanding, a filter covering a drain in the packer expands from a first unexpanded position to a second expanded position;
- and
- sampling the fluid through the filter.
