A sampling assembly has an inner expandable packer, and an outer layer formed by rings may be disposed about and/or may be positioned on the outer surface of the inner expandable packer member. Drains may be positioned between the rings and may be located under ports positioned between the rings. Flowlines may be connected to the drains, may be positioned in the rings and may extend through the rings. For each of the ports, a plate may be positioned between the port and the laterally adjacent port. The flowlines may be connected to a downstream component, such as a fluid analysis module, a fluid containment module and/or the like.

System and method for sampling assembly with outer layer of rings

A system and/or a method collects formation fluids using a single packer with expansion rings and/or an irregular sealing layer. The packer may have an expansion ring extending around an outer circumference. The expansion ring may seal a portion of a wellbore to sample fluid from a formation. An irregular sealing layer may facilitate leaking between drains of the packer. The irregular sealing layer may have grooves through which fluid may flow. The irregular sealing layer may be composed of fibers and/or plastic.

Single packer with a sealing layer shape enhanced for fluid performance

A technique involves collecting formation fluids through a single packer. The single packer comprises an outer bladder with drains positioned in the outer bladder to obtain formation fluid samples. Features also may be incorporated into the single packer to limit sealing in the circumferential spaces between the drains and to provide a larger sampling surface than provided simply via the drain surface area.

System and method related to a sampling packer

Filtration systems, methods and/or apparatuses for use on a packer system are provided. Filtration assemblies and/or filters may prevent mud, gravel, and/or other solids from clogging and/or entering drains on a packer. The filters and/or filtration assemblies may have multiple dynamic components to prevent debris from entering the packer system. Rotary filters, cylindrical filters, and/or belt filters may be used to clear fluid obstructions from sampling drains. Helices and/or turbines may harness power of fluid flowing through the drains and/or flowlines to operate moving dynamic components of systems and/or apparatuses. The filters and/or filtration assemblies may be interchangeable such that various filters may be used on a single packer system.
