Abstract: A testing system includes a main wellbore, at least one injection tunnel and production tunnel, a monitoring system including at least one sensor, and a recovering tube. The injection and production tunnels are parallel with each other and extend perpendicularly from the main wellbore. The method for conducting in-situ oil recovery sweep testing includes introducing an injection fluid into a main wellbore and at least one injection tunnel, monitoring conditions of the at least one production tunnel, and collecting produced fluid from the production tunnel with a recovering tube. A method for conducting sequential in-situ oil recovery sweep testing includes locating a recovering tube in a target production tunnel and conducting a sweeping process. The sweeping process includes introducing an injection fluid into an injection tunnel, monitoring conditions of the target production tunnel, collecting a produced fluid from the target production tunnel, isolating the target production tunnel, and repeating.
