Abstract
Methods and systems for depassivating completion tool batteries are provided. In one embodiment, the methods comprise: providing a completion tool disposed within a wellbore penetrating at least a portion of a subterranean formation, wherein the completion tool is electrically coupled to an at least partially passivated lithium battery; depassivating the at least partially passivated lithium battery in the wellbore by discharging the lithium battery; and powering the completion tool with the at least partially depassivated lithium battery.
Claims19
A method comprising:
- providing a completion tool disposed within a wellbore penetrating at least a portion of a subterranean formation, wherein the completion tool is electrically coupled to an at least partially passivated lithium battery;
- depassivating the at least partially passivated lithium battery in the wellbore by discharging the lithium battery, wherein the depassivating comprises:
- measuring a resistance of the battery;
- and
- depassivating the battery based on the measured resistance of the battery;
- and
- powering the completion tool with the at least partially depassivated lithium battery.
A system comprising:
- a production string disposed in a wellbore penetrating at least a portion of a subterranean formation;
- and
- a completion tool coupled to the production string, wherein the completion tool comprises a lithium battery and a controller configured to depassivate the lithium battery by drawing current from the lithium battery, wherein the depassivating comprises:
- measuring a resistance of the battery;
- and
- depassivating the battery based on the measured resistance of the battery.
A system comprising:
- a production string disposed in a wellbore penetrating at least a portion of a subterranean formation;
- and
- a plurality of completion tools coupled to the production string, wherein each of the plurality of completion tools comprises a lithium battery and a controller configured to depassivate the battery by drawing current from the lithium battery, wherein the depassivating comprises measuring a resistance of the battery and depassivating the battery based on the measured resistance of the battery.
