General aspects of deepwater petroleum exploration and production were identified and related technical challenges were addressed. Historical perspectives, insight, processes, and engineering applications are reviewed to enhance the design capability of the domestic offshore industry. The technical challenges and unique aspects of deepwater exploration and production were identified. The assessment of deepwater exploration, drilling, and production systems is a key stage for performing the front end engineering design (FEED). The global trends in deepwater development, including the feasibility for Korea, were reviewed.

현재 심해에서의 석유개발을 위하여 사용되는 구조물의 설계 및 해석에 관한 기술은 수심 약 600 m까지 어느 정도 확립되어 있고, 또한 극지환경하에서의 석유개발용 구조물에 관한 기술도 상당한 수준에 올라 있다고 판단된다. 그러나 아직도 많은 분야에 걸쳐 기술의 개발과 개선을 요구하고 있다. 아울러 이에 관계되는 많은 문제들은 구조공학적인 분야만이 아니라 기계, 재료, 전자, 조선, 해양공학 등 거의 모든 공학분야의 기술이 총체적으로 지원되어야만 해결이 가능하게 된다. 본 고에서는 심해 및 극지유전개발에 사용되고 있는 구조물을 소개하고 이들이 가지고 있는 기술적인 문제점에 대해서 살펴보고자 한다.

Deepwater oil is becoming more attractive because most onshore and shallow water oil is developing or developed. With the on-going trend to deepwater oil developments, flow assurance problems which prevent oil flow from reservoir to processing facilities are becoming an issue because deposited material can be occurred in case oil is exposed to very different environment from reservoir. Wax deposition which is one of flow assurance problems can be a major technical and economic issue because it is very sensitive to temperature. In order to predict and mitigate wax problems, the precise measurement of wax appearance temperature (WAT) which is the starting temperature of wax precipitation is very important. Various methods have been suggested for WAT measurement of opaque oil because there is no standard method for opaque oil. In this study, the WAT of opaque oil samples was measured using viscosity measurement method, differential scanning calorimetry, filter plugging method, and pressurized filter plugging method. Wax deposition test and high temperature gas chromatography analysis were applied to verify measured WAT. As a result of study, the WAT of opaque oils was successfully measured and verified. If WAT measurement methods of opaque oil related to oil characteristics is systematized using the results of this study, it can be a valuable tool for WAT measurement of opaque oil and flow assurance related to wax deposition.

The shortage of proven hydrocarbon reserves has resulted in exploration progressing from the offshore into progressively deeper water of the continental shelf. Despite the success of seismic acquisition at ever greater depths, there are marine geological terrenes in which the interpretation of seismic data is difficult, such regions dominated by scattering or high reflectivity that is characteristic of carbonate reefs, volcanic cover and submarine permafrost. A marine controlled-source electromagnetic (CSEM) method has recently been applied to the oil and gas exploration thanks to its high-resistivity characteristics of the hydrocarbon. In particular, this method produces better results in terms of sensitivity under the deep water environment rather than the shallow water. Only in the last five years has the relevance of CSEM been recognized by oil companies who now use it to help them make exploration drilling decisions. Initial results are most promising and several contractors now offer magnetotelluric and CSEM services.

Azerbaijan, located on western part of Caspian Sea, has been developed oil and gas exploration and production business from about 200 years ago and once charged of 50% of world oil production in the early 20th century. After Azerbaijan was independent of Soviet Union in 1991, foreign oil companies, including Korean oil companies, have been investing in Azerbaijan oil business on offshore blocks. Productive capacity of downstream in the Azerbaijan is lower than productive capacity of upstream, whereas there are important pipelines, such as BTC, SCP, NREP, and WREP, provide opportunities of the oil and gas exporting to the world. Oil fields in onshore blocks in the Azerbaijan are almost mature oil fields, caused by high recovery rate. Offshore oil blocks are still high potential in oil exploration with high risk.

This study is focused on concepts and types of drilling investigating the scope of activity and problems the application of marine environment and safety acts related to deep-sea drilling for the development of the continental shelf in Korea. For the systemic development of subsea mineral resources, this study suggest a legislative proposal for the establishment of a separate law based on the UK Offshore Installation (Safety Case) regulation and improvement of the marine environment management act, maritime safety act and oil & mining safety regulation. Specially, this study emphasized on the necessity of establishing education, training and evaluation system according to the international certification training for the domestic work force based on accident cases related to overseas offshore plants.

The development of limited petroleum resources for use with mankind inevitably explores and seeks to develop oil fields in the deep sea area, under the rise of the oil prices market situation. The use of Oceanic Thermal Energy Conversion (OTEC) technology, which operates the power generation facility using the temperature differences between the deep water and the surface water, is progressing actively as a trend to follow. In this study, the application of the Discharged Thermal Energy Conversion (DTEC) was designed and analyzed under the condition that the supply condition of seawater used in the FPSO installed in the deep sea area is changed up to 400m depth. In this case, it was confirmed that the design of the system that can generate more electric power according to the depth of water is confirmed, by thus applying the DTEC system by taking the cooling water at a deeper water depth than the existing design water depth. The FPSO considers the similarity of the OTEC power generation facilities, and will apply the DTEC system to FPSO in the deep sea area to accumulate technology and the conversion to further utilize the OTEC power generation facilities after the end of life cycle of oil production, which could be a solution to two important issues, namely, resource development and sustainable development.
