With the decline in discoveries of new oil fields and increasing demand from developing countries it is believed that enhanced oil recovery (EOR) technologies will play a key role to meet the energy demand in years to come. Based on the recently-published data, this paper discusses current status of global EOR market and technical development trends. The EOR market includes oil produced through various EOR recovery methods, such as thermal recovery, gas injection, chemical injection. Also, EOR methods are addressed screening criteria by reservoir and fluid characteristics including lithology, depth, thickness, and oil properties such as composition and gravity. Finally, the examples of field applied by various EOR methods are discussed with respect to reservoir characteristics and performance.

한국 경제에 근간이 되는 산업은 제조업이고, 그중 석유화학산업은 전량 원유를 수입하여 우리나라의 기술력으로 가공하여 재수출하는 전략적 성장 산업이다. 수많은 제조업의 원료가 되는 원유를 전량 해상운송을 통해 수입하는 우리나라는 변동성이 심한 유조선 운임 시장에 대해 기민하게 대응해야 한다. 유조선 운임 시장의 위기는 관련 해운회사의 위기에서 끝나지 않고 원유를 사용하는 산업에서부터 국민의 생활까지 영향을 미칠 수 있으므로, 본 연구에서 신호접근법을 활용한 조기경보모형을 제시했다. BDTI 운임지수를 활용하여 유조선 해운시장 위기를 정의하고, 38개의 거시경제, 금융, 원자재 지표 그리고 해운시장 데이터를 활용해 시차상관관계를 분석하여 유조선 해운시장 위기에 선행적으로 반응하는 종합선행지수를 도출했다. 연구 결과, 종합선행지수는 두 달 전 가장 높은 0.499의 시차상관계수 값을 가졌으며, 5개월 전부터 유의미한 상관계수 값을 나타냈다. 더불어 QPS 값은 0.13으로 위기 예측에 대해 높은 정확성을 지니는 것으로 검증됐다.

Northeast Asia where is an epicenter of the global financial crisis's conquest is traditional imbalanced region of oil production and consumption. In recent years, the region has been suffered by the shortage of oil storage and transportation facilities due to surging oil trading and necessity in strategic reserves. Therefore, since independent petroleum logistics with the storage facilities and oil trading hub is required to form efficient oil market in this region. In this study, we analyzed the efficiency of refinery facilities by country that is of importance in being a logistics hub in Northeast Asia by employing non-static and dynamic efficiency analysis, which are a part of DEA(Data Envelopment Analysis) and then policy implications have been drawn. The result illustrates Korea's is the highest country in terms of efficiency of oil refining facilities in Northeast Asia. It implies that Korea has strong position to be the oil hub in Northeast Asia.

주요 현물유가(WTI, Brent, Oman, Dubai)와 선물유가간의 동태적 관계를 시계열 분석 방법을 이용하여 살펴보았다. 현물유가 및 선물유가들은 1차 적분된 시계열(I(1))로 보여진다. 현물유가들사이 및 현물유가와 선물유가사이에도 공적분관계(cointegration relation)가 있는 것으로 보여진다. 한편, 선물유가는 현물 유가를 인과(Granger-cause)하지만, 현물유가는 선물유가를 인과하지 않는 것으로 나타났다. 이러한 공적분관계 및 인과관계의 결과는 합리적 기대가설(rational expectations hypothesis)에 의한 효율적 석유시장(efficient oil markets)과 일치하는 것으로 보여진다. 수정오차모형(error correction model)에 의해 3/4분기 및 4/4분기의 유가들을 예측해 보았다.

세계 자전거 시장에서 절대 빼놓을 수 없는 브랜드 중 하나가 바로 트렉(TREK)이다. 석유 파동과 함께 미국의 자전거 산업이 커지기 시작한 1970년대 중반(1976년), 5명의 장인들이 헛간에서 품질 좋은 자전거를 만들겠다는 마음가짐으로 시작된 트렉은 현재 세계에서 가장 큰 자전커 브랜드로 성장했기 때문이다.

Interest of unconventional Oil and Gas, which is produced in a different way, has been increasing due to exhaustion of traditional oil and gas. However production of unconventional Oil and Gas is closely related to its technology level. Accordingly in this research, we can analyze technology level of unconventional Oil and Gas with country/sector/year patent analysis. Through the result of this research, U.S is highest patent application national, patent application in oil sand is increasing. In addition, oil sands-realated patents and shale oil-realated patents applying actively in early 1970's and since the mid-1980's showed a decreasing trend. And patent application in unconventional oil and gas has been increasing due to the rise in the oil price 2000's.

Since the liberalization of petroleum product prices in 1997, there has been persistent suspicion with regard to asymmetry in the movement of petroleum product prices in Korea. In particular, academics and consumer groups suggest that prices decided by refining companies and gas stations have moved asymmetrically compared with international petroleum product prices. The primary aim of this study is to determine, using the Error Correction Model, to perform multi-country asymmetry analysis including the United States, the United Kingdom, Germany, France, Italy and Japan. We shows that comparison of domestic prices with international prices in the six countries mentioned above revealed a fairly low level of asymmetry in those countries, although some asymmetry was found in some countries at various times within the period of analysis. To explain the different degrees of asymmetry between countries, this study looked at asymmetry in the United States, Germany and Italy and sought correlations between each country's oil industry structure and its level of competition.

This paper investigates an oil refiner's asymmetric behavior in the adjustments of gasoline and diesel prices to changes in his own price and his rivals' prices as well as input costs. An asymmetric error correction model which allows a firm's pricing behavior to the deviation of other firms' prices from their long-run equilibrium level is employed for estimation using weekly data for the period April 2009 to January 2015. Evidence is found that there is a significant degree of asymmetry in the adjustment of wholesale prices to changes in crude oil price. A similar result in regard to the exchange rate is also found by the data. The estimation results for firm's response to changes in other firms' prices indicates that implicit collusion could be more easily exploited in the wholesale petroleum market as results of firms' interaction with each other and anticipation of rivals' pricing behavior. A few refiners show competitive price adjustment in response to the upward deviation of the others' prices from their equilibrium level.

Prices of oil products such as gasoline and diesel are deregulated since 1997 while electricity price is still controlled by government. This difference may explain recent discrepancy in the patterns of demand for oil products and electricity - constant increase in electricity consumption and stagnant demand for oil. To verify it empirically, we estimate price and income (production) elasticity of demand across time by using a rolling regression with 10 year-window based on monthly data for 1981-2011. Estimation results show that the sensitivity to price in demand for gasoline and diesel has increased since mid-90s while the elasticity of demand for electricity has become smaller. Second, income (production) elasticities of demand have shown no significant changes for both oil products and electricity. Third, cross-price elasticity was found meaningful only for gasoline before mid 1990s and for diesel after then.
