PUMP DRAIN ARRANGEMENTS FOR PACKER SYSTEMS AND METHODS FOR SAMPLING UNDERGROUND FORMATIONS USING SAME

摘要

An apparatus, system and method of sampling a reservoir fluid is disclosed. An inflatable packer is deployed into a wellbore having one or more fluid ports for receiving the reservoir fluid. The fluid ports are positionable at different longitudinal and/or radial positions. One or more pumps are connected to the fluid ports and are within the packer. A fluid exit may optionally beprovided in the packer to expel the reservoir fluid received from one of the fluid ports back into the wellbore.
