Abstract: Described is a method for mitigating tar in a reservoir. Tar-mitigating bacteria is introduced downhole to a reservoir with tar. The tar-mitigating bacteria are delivered to a tar food source in the reservoir, triggering bacterial growth upon reaching the tar food source. The tar breaks apart, allowing the tar-mitigating bacteria to produce and release biosurfactants, thereby trapping the tar from the reservoir with the biosurfactants. The tar trapped by the biosurfactants is mobilized away from porous rock, and the trapped tar is removed from the reservoir.

The ultrasonic signal is reflected by the wellbore fluid within the bell nipple resulting in an ultrasonic response signal. The ultrasonic response signal is caused to be received by the ultrasonic transceiver. Based on the ultrasonic response signal, it is determined whether the fluid level within the bell nipple is static or mobile.
