Deepwater Hydrocarbon Exploration in China Seas: Yesterday, Today and Tomorrow

Zhi-gang Zhao,Hai-zhang Yang,Wu Tang,Shi-xiang Liu

《工程管理前沿（英文）》 2016年第3卷第4期页码 390-395 doi: 10.15302/J-FEM-2016059

摘要： Deepwater area has been one of the hottest areas in the global hydrocarbon exploration. However, deepwater hydrocarbon exploration in China started late and mainly concentrated in the South China Sea (SCS) with low level of researches. Although there are some achievements, there are even more challenges. For this reason, this paper reviewed the history of deepwater exploration in China Seas and summarized the current exploration situation. The future directions of deepwater hydrocarbon exploration mainly consist of five aspects: establishing key technology system of complex structure and reservoir seismic acquisition and processing in deepwater areas of SCS, clarifying the development mechanism of high quality source rock and establishing matching assessment technology, studying the formation conditions of favorable reservoir and creating reservoir identification technology, improving accumulation theory of large and medium-sized oil and gas field of deepwater, deepening the researches of petroleum geology conditions of middle and south part of SCS. Simultaneously, the concept of portfolio should be utilized in the exploration process, with economic benefits considered. These understandings will help guiding the future deepwater hydrocarbon exploration in China Seas.

Wen-ming Han,Shui Yu,Hong-yan Zhao,Yang Zhao,Liang Chen

《工程管理前沿（英文）》 2016年第3卷第4期页码 314-320 doi: 10.15302/J-FEM-2016050

摘要： Deepwater offshore area, with rich oil and gas resources, has currently become the hot area for oil and gas exploration and the main battlefield where global oil majors compete with each other. This article summarizes the current situation of deepwater oil and gas exploration and development overseas from the perspectives of exploration history, exploration achievements and technical progress, and analyzes the difficulties and challenges faced by the industry, such as low level understanding of hydrocarbon accumulation conditions, global security and environmental challenges. And then, several feasible implementation strategies have been proposed on how to actively deal with the challenges, promote Chinese oil companies’ overseas exploration, and realize efficient exploration and development of deepwater oil and gas fields overseas. These strategies consist of three aspects: profit-oriented operation principle, exploration ideas supported by theory and technology, and exploration strategy that puts safety first. In the era of low oil prices, Chinese oil companies must build up confidence, seize the opportunity and face the challenge while taking efforts to innovate technologies and theories, updates strategic ideas, and cultivate deepwater talents so as to be in an active position in global deepwater exploration and development industry in the future.

A Fast Evaluation and Research Method for Exploration Potential of Oversea Basins

Hong-quan Kang,Yun-hua Deng,Huai-cun Jia,Tao Cheng,Bo Bai

《工程管理前沿（英文）》 2016年第3卷第4期页码 338-342 doi: 10.15302/J-FEM-2016052

摘要： Oversea hydrocarbon exploration always faces some problems, such as multiple basin types, different exploration prospects, various exploration degrees, diverse data quantities and geological recognitions. This paper focuses on overseas basins with different exploration degrees and offers a new evaluation system and research method for fast evaluation and risk analysis on hydrocarbon potential. Based on the theory of probability, this new evaluation system evaluates each parameter and core accumulation factor with comprehensive and quantitative assignment, to accelerate geological evaluation. In addition, this paper suggests that source rock evaluation should be the core criterion in screening evaluation of poor-explored basins, and also proposes that both the exploration potential and geological recognition should drive the evaluation for basins with high exploration degrees. This new system and method, which is an effective system for fast basin evaluation, is suggested to be used in oversea evaluation and decision-making objectively, scientifically and efficiently.

Bao-quan Yang,Li Yang,Fan-jie Shang,Xin Zhang,Chen-xi Li

《工程管理前沿（英文）》 2016年第3卷第4期页码 356-361 doi: 10.15302/J-FEM-2016057

摘要： Deepwater oilfields will become main sources of the world’s oil and gas production. It is characterized with high technology, huge investment, long duration, high risk and high profit. It is a huge system project, including exploration and appraising, field development plan (FDP) design, implementation, reservoir management and optimization. Actually, limited data, international environment and oil price will cause much uncertainty for FDP design and production management. Any unreasonable decision will cause huge loss. Thus, risk foreseeing and mitigation strategies become more important. This paper takes AKPO and EGINA as examples to analyze the main uncertainties, proposes mitigation strategies, and provides valuable experiences for the other deepwater oilfields development.

exogenous degrader-enhanced bioremediation with low-dose persulfate oxidation for polycyclic aromatic hydrocarbon

《环境科学与工程前沿（英文）》 2023年第17卷第11期 doi: 10.1007/s11783-023-1733-x

摘要： Polycyclic aromatic hydrocarbon (PAH)-contaminated soils are usually complex and characterized by a lack of nutrition and soil salinization, resulting in difficulties in soil remediation. In this study, bioaugmentation with a PAH-degrading Bacillus PheN7 (BA) and low-dose persulfate oxidation (PS), along with natural biodegradation, were utilized to remediate alkaline PAH-contaminated soil. The soil used in the study had a pH of 9.35, and the total PAH content was 568.8 ± 31.0 mg/kg dry soil. After 42 d of remediation, the degradation efficiency of PAHs was 96.72% and 93.88% using persulfate oxidation and bioaugmentation, respectively, whereas 38.66% of PAHs were degraded in natural attenuation (NA). Bacillus was the dominant genera throughout the process of bioremediation with the relative abundance of 79.3% on day 42 in the BA system, whereas, Alcanivorax was enriched and became the dominant genera in PS systems. In the meantime, PAH degradation genes were detected with remarkably higher level in the BA system than in PS system during the remediation. In addition to the degradation of contaminants, persulfate oxidation promotes microbial bioremediation efficiency mainly by lowering the pH to neutral and increasing the active phosphorus content in the soil. Microbial species and ecological niches were less reduced in the PS system than in the BA system. Collectively, persulfate oxidation had a better impact on the soil microbiome and is more suitable for long-term soil health than bioaugmentation through PheN7 addition.

Analysis of physical properties of gas hydrate-bearing unconsolidated sediment samples from the ultra-deepwater

《能源前沿（英文）》 2022年第16卷第3期页码 509-520 doi: 10.1007/s11708-021-0786-4

摘要： Marine natural gas hydrate has recently attracted global attention as a potential new clean energy source. Laboratory measurements of various physical properties of gas hydrate-bearing marine sediments can provide valuable information for developing efficient and safe extraction technology of natural gas hydrates. This study presents comprehensive measurement results and analysis of drilled hydrate-bearing sediments samples recovered from Qiongdongnan Basin in the South China Sea. The results show that the gas hydrate in the core samples is mainly methane hydrate with a methane content of approximately 95%, and the other components are ethane and carbon dioxide. The saturation of the samples fluctuates from 2%–60%, the porosity is approximately 38%–43%, and the water content is approximately 30%–50%, which indicate that high water saturation means that timely drainage should be paid attention to during hydrate extraction. In addition, the median diameter of the sediment samples is mainly distributed in the range of 15 to 34 μm, and attention should be paid to the prevention and control of sand production in the mining process. Moreover, the thermal conductivity is distributed in the range of 0.75 to 0.96 W/(m∙K) as measured by the flat plate heat source method. The relatively low thermal conductivity of hydrates at this study site indicates that a combined approach is encouraged for natural gas production technologies. It is also found that clay flakes and fine particles are attached to the surface of large particles in large numbers. Such characteristics will lead to insufficient permeability during the production process.
