    摘要: 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.
