A fluid sampling probe may include one or more features that increase the likelihood that a seal will be maintained during a sampling operation, even for sampling operations in unconsolidated formations. This may reduce contamination in formation fluid samples that are obtained during sampling operations. The fluid sampling probe may include a reinforcement ring configured to extend into a geological formation beyond an elastomer portion of the fluid sampling probe, which may support the geological formation and prevent a failure of the formation during sampling operations. The fluid sampling probe may also include a stop sleeve to prevent overextension that could otherwise cause the geological formation to collapse. In addition, the fluid sampling probe may include a relatively wider sealing elastomer that may decrease in height monotonically radially from the center of the fluid sampling probe.
