Abstract: Overseas risk exploration projects are faced with the threats of geological conditions, political situation, fi nance and taxation items and so on in the running process, resulting in the limit of incertitude factors and self-experience as for the management, and the exploration decision is normally difficult to make and the operation methods may be improper, associated with the pressure of HSE and the problem of staff instability. Aiming at these problems, project managers should make appropriate exploration decisions from the angle of full risk management, and establish scientifi c and systematic evaluation system and response system by understanding the internal relationship among different risk factors. Overseas exploration projects are confronted with uncertainty factors such as space, time, budget, goal and task and so on in terms of management control, so they need to be constantly adjusted and optimized in terms of decisions and strategies in line with external factors. Domestic oil enterprises should continue to improve the quality of personnel, make efforts to improve the level of bidding, decision demonstration, and HSE management to be in line with international standards. By improving the technical strength and management level to maximize economic benefi ts of overseas exploration, it will precipitate overseas exploration to develop effi ciently and scientifi cally
