Abstract:
1. A system for collecting at least one measurement within a borehole formed in a subsurface reservoir comprising: a first packer having a first expandable element and a first port formed in a first layer of the first expandable element, wherein the first expandable element comprises a flexible material configured to abut a wall of the borehole; a drawdown pump or drawdown piston disposed in the first packer and coupled to the first port; a first wireless sensor located at the first port and configured to move together with the first expandable element; a second packer having a second expandable element and a second port formed in a second layer of the second expandable element, wherein the second expandable element comprises the flexible material; a drawdown pump or drawdown piston disposed in the second packer and coupled to the second port; a second wireless sensor located at the second port and configured to move together with the second expandable element; and a wireless transceiver located at a position between the first packer and the second packer wherein the first and second wireless sensors are each configured to receive at least one wireless signal from said wireless transceiver, and collect at least one measurement or perform at least one task related to the borehole or subsurface reservoir about the borehole and provide a response back to the wireless transceiver.
