METHODS AND SYSTEMS FOR MONITORING A SUBTERRANEAN FORMATION AND WELLBORE PRODUCTION

摘要

Methods of monitoring conditions within a wellbore comprise providing a plurality of signal transmitters and a plurality of signal receivers within the wellbore. Marker materials configured with a particular characteristic may interact with signals generated by the plurality of signal transmitters are introduced into the wellbore. The marker materials interact with the signals, forming modified signals. The modified signals are received by the plurality of signal receivers. The plurality of receivers are configured to measure at least one of acoustic activity and an electromagnetic field to determine a location of the marker materials. The electrical conductivity and the magnetism of produced fluids may also be measured to determine a producing zone of the produced fluid. Downhole systems including the marker materials and also disclosed.

1. A method of detecting a location of fluids within a wellbore, the method comprising:
providing a plurality of signal transmitters and a plurality of signal receivers in a wellbore at least intersecting a subterranean formation; injecting first marker particles having a first characteristic into a first zone of the subterranean formation and attaching the first marker particles to organic surfaces within the first zone; injecting second marker particles having a second characteristic different than the first characteristic into a second zone of the subterranean formation and attaching the second marker particles to organic surfaces within the second zone; generating a signal with at least one of the plurality of signal transmitters and transmitting the signal through the first marker particles and the second marker particles; and detecting at least one of an acoustic activity and an electromagnetic field with at least one signal receiver of the plurality of signal receivers and detecting a location of at least one of the first marker particles and the second marker particles.
