That the oil and gas exploration and development is extending into deep water proceeds the rapidly shift to subsea production system. However, complex subsea equipment and frequency offshore accidents aroused the concern on the risk assessment of subsea system. The paper illustrates the hazard aspects which should be focused on in the subsea equipment compared with the surface equipment. The hazards identification and risk analysis on subsea X-tree system is carried out. A general risk-prevent process of subsea X-tree system is illustrated, so does the reliability analysis process. Besides, some commendations on subsea detection and maintenance are presented in the paper.

As the leading of oil and gas exploration and development, oil-gas drilling operations with high investment, high technology, and other industries interchange and perennial wild characteristics, there are various HSE risks during operation. Constructing HSE risk assessment system of oil-gas drilling operations, using AHP to construct indicators were analyzed and compared, and calculate the index weight. Then build fuzzy evaluation matrix based on expert evaluation method, get fuzzy evaluation result is "high risk". Finally, from four aspects (people, object, environment, and management) proposed HSE control measures.

Impact Risk

Climatic degradation of equipment, in combination with stringent requirements for human safety and minimalistic environmental impact, need to be addressed through improved risk assessment in vulnerable areas, such as the Arctic. The performance of technologies and risk related to its utilization, for example in terms of autonomous operations, significantly impact future requirements for oil and gas exploration and production. An interdisciplinary and systemic approach integrating both risk to the environment and to humans is needed as the challenges related to operation in extreme environments directly impact risk, costs, and the general societal acceptance of the activities. Development of such an approach focusing on autonomous underwater vehicles (AUV) and operations is addressed in this paper.

Offshore Oil

Environmental impact from offshore oil and gas exploration and production is likely to arise from five main sources—produced formation water, drilling fluids and cuttiftgs, industrial chemicals used in production activities, accidental oil spills and the physical disruption of the marine environment by coastal and offshore engineering works. The principle task of environmental managers is to evaluate the risk of impact on the marine environment from their company's activities and to formulate and implement company policy and procedures aimed at minimising this risk. Of critical importance is the determination of the extent and scope of the environmental program designed to control and monitor impacts.The development of environmental management programs in the oil and gas industry involves two main processes—ecological risk assessment and formulation of a monitoring program. This review outlines the steps involved in ecological risk assessment with specific reference to the offshore oil and gas industry. Information is presented on the basic principles involved in risk assessment, the main source of environmental impact from offshore oil and gas exploration and production and the different approaches that can be used to predict and monitor impacts. Approaches for improving the cost efficiency of ecotoxicological testing are discussed. Results of recent ecotoxicological studies on a biocide preparation and two corrosion inhibitors used in oil and gas production activities on the North West Shelf are also presented.

Independent Assessment

Regulatory bodies in Australia are taking an increasing interest in quantified risk assessment for assessing the significance of risks to worker safety and the environment associated with oil and gas exploration and production. In principle, quantified risk assessment (QRA) provides an objective, independent assessment of the risks associated with a particular activity or development, thereby enabling risk management decisions to be better informed. However, there are significant uncertainties associated with QRA which limit its potential to contribute to decision making.This article considers the limitations of QRA in decision making and proposes a policy framework within which safety and environmental risks can be assessed and decisions made. The proposed framework considers issues such as uncertainty in QRA, risk communication, the role of regulatory bodies and the need for credibility in the QRA process. The role of QRA is seen as assisting in clarifying the implications of various courses of action for decisionmakers, assisting in making decisions on safety issues and bringing a structured and analytical approach to assessments.

Extended Reach Drilling

Drilling is one of the major means for oil and gas exploration and development. Extended reach wells (ERWs) are defined as directional wells or horizontal wells with horizontal displacement (HD) to vertical depth (VD) ratio greater than or equal to 2. Extended reach drilling (ERD) confronted many technical difficulties. Risk analysis of ERD before drilling is of great significance for preventing complex accidents during drilling operations, improving the drilling rate and efficiency. Based on gray matter-element theory, this paper established a comprehensive risk assessment model for ERD operations and applied this model to evaluate the drilling risk of Well B6ERW07(HD to VD ratio 5.94, horizontal displacement 7,419.42 m, vertical depth 1,248.50 m, measured depth 8,144.31 m)in the Liuhua oil field, South China Sea. The assessment results show that the predicted success rate of drilling this ERW is 49.9%. This result can be important criteria and thus contributes greatly to decision making.
