| 1 | Co-optimization of carbon dioxide storage and enhanced oil recovery in oil reservoirs using a multi-objective genetic algorithm(NSGA-Ⅱ)显示文摘Climate researchers have observed that the carbon dioxide(CO2) concentration in the atmosphere have been growing significantly over the past century. CO2 from energy represents about 75% of the greenhouse gas(GHG) emissions for Annex B(Developed) countries, and over 60% of global emissions. Because of impermeable cap rocks hydrocarbon reservoirs are able to sequester CO2. In addition, due to high-demand for oil worldwide, injection of CO2 is a useful way to enhance oil production. Hence, applying an efficient method to co-optimize CO2 storage and oil production is vital. Lack of suitable optimization techniques in the past led most multi-objective optimization problems to be tackled in the same way as a single objective optimization issue. However, there are some basic differences between the multi and single objective optimization methods. In this study, by using a nondominated sorting genetic algorithm(NSGA-II) for an oil reservoir, some appropriate scenarios are proposed based on simultaneous gas storage and enhanced oil recovery optimization. The advantages of this method allow us to amend production scenarios after implementing the optimization process, by regarding the variation of economic parameters such as oil price and CO2 tax. This leads to reduced risks and time duration of making new decisions based on upcoming situations. | SAFARZADEH Mohammad Amin MOTAHHARI Seyyed Mahdia | 2014 | Petroleum Science2014，11，3： | 6 |
| 2 | 未开发远景区页岩气的综合评价方法--以伊朗卢雷斯坦页岩气区为例显示文摘页岩气评价方法及关键参数研究表明,仅靠技术指标来寻找地质甜点并不能实现页岩气的商业经济开发。通过将总有机碳含量、镜质体反射率等技术指标与内部收益率、投资回收期等经济指标相结合,提出一套经济指标和技术指标相结合的研究方法,用以筛选页岩气未开发区的最佳技术经济开发甜点。采用该方法通过总有机碳含量、镜质体反射率、有效储集层厚度和含气量等参数筛选21个地质甜点。再基于类比研究法,以压力梯度、黏土矿物含量、埋藏深度等参数为类比依据,选择Eagle Ford页岩为类比对象,提取采收率和生产曲线两项指标,估算研究区的技术可采储量。在此基础上,结合内部收益率、投资回收期等经济指标评价地质甜点的经济性。应用这套多参数综合评价方法,对伊朗卢雷斯坦地区白垩系页岩气储集层S_(1)层和S_(2)层进行评估,确定该区域的最佳技术经济开发甜点。结果表明,在净现值取其P_(10)值(累计概率10%时对应的参数值)的情况下,技术可采储量和经济可采储量总量分别为7875×10^(8)m^(3)和4306×10^(8)m^(3),有11个地质甜点具有商业开发价值,其中1号甜点价值最高,净现值为35×10^(8)美元。 | ABDOLLAHI Reza MOTAHHARI Seyed Mahdia ASKARI Amir Abbas HEMATPUR Hamed ZAMANI Ziba TIRTASHI Rahim Bagheri DARYABANDEH Manouchehr 陈浩 | 2022 | 石油勘探与开发2022，49，3： | 1 |

| 6 | A systematic step-wise approach for shale gas assessment in undeveloped prospects:A case study of Lurestan shale gas area in Iran显示文摘Key parameters and evaluation methods of shale gas show that it is not possible to guarantee the commercial and economic development of shale gas by sorting out geological sweet spots only according to technical indicators.A research method combining technical indicators including total organic carbon content and vitrinite reflectance with economic indicators including internal rate of return and investment payback period is proposed to screen the best technological and economic development sweet spots in undeveloped areas.This method was used to evaluate the best technological and economic development sweet spots in Cretaceous shale gas reservoirs S_(1) and S_(2) of Lurestan area,Iran.Twenty-one geologic sweet spots were picked out based on effective reservoir thickness,vitrinite reflectance and gas content.Based on analogy method,the pressure gradient,clay mineral content,buried depth and other parameters were taken as comparative indicators,the Eagle Ford shale as comparison object,recovery factor and production curve were extracted to estimate the technologically recoverable reserves of the study area.On this basis,the economic indexes such as internal rate of return and investment payback period were used to evaluate the economy of the geological sweet spots.In the case of P_(10) distribution,the total technologically recoverable reserves and economically recoverable reserves are 7875×10^(8)m^(3) and 4306×10^(8)m^(3) respectively,11 geological sweet spots have commercial development value,among which,No.1 sweet spot has the highest value,with a net present value of 35×10^(8) USD. | ABDOLLAHI Reza MOTAHHARI Seyed Mahdia ASKARI Amir Abbas HEMATPUR Hamed ZAMANI Ziba TIRTASHI Rahim Bagheri DARYABANDEH Manouchehr CHEN Hao | 2022 | Petroleum Exploration and Development2022，49，3： | 0 |
