Abstract
KN area is located in the East of KN depression in Muglad Basin. It has lower exploratory level, only two-dimensional survey lines are distributed in most areas before, and the quality of seismic data is poor. Three wells have been drilled in this area, only one well has low oil production in Bentiu formation, and the other two wells have failed. However, oil was discovered in multiple targets in H area, which is in the SouthEast of KN area. In order to evaluate the oil and gas potential of KN area, combined with the new seismic data of KN 3D area, it is carried out of comprehensive geological and geophysical research work in KN area. By means of well correlation, precise seismic interpretation, tectonic evolution analysis and drilled wells analysis, and comparing with the reservoir forming conditions of adjacent H area, it is concluded that the oil source fault and forming time of traps are the important factors to form the oil and gas reservoir. On this basis, the residual potential of KN area is reevaluated, and it is concluded that the Eastern fault step zone is a favorable area for further exploration.
