| 1 | Screening of inhibitors for remediation of asphaltene deposits: Experimental and modeling study显示文摘One of the most severe problems during production from heavy crude oil reservoirs is the formation of asphaltene precipitation and as a result deposition in the tubing,surface facilities and near wellbore region which causes oil production and permeability reduction in addition to rock wettability alteration in the reservoir.So one of the economical ways to prevent such incidents is using the chemicals which are called asphaltene inhibitor.In this study,the influence of three commercial inhibitors,namely;Cetyl Terimethyl Ammonium Bromide(CTAB),Sodium Dodecyl Sulfate(SDS),Triton X-100 and four non-commercial(Benzene,Benzoic Acid,Salicylic Acid,Naphthalene)inhibitors on two Iranian crude oils were investigated.This study extends previous works and contributes toward the better understanding of interactions between asphaltene and inhibitor.Effect of functional groups and structure of inhibitors on asphaltene precipitation were studied and it seems clear that the nature and polarity of asphaltene(structure and amount of impurities presented)has a significant impact on the selection of inhibitors.asphaltene dispersant tests and Core flood tests were designed for evaluation of inhibitors in static and dynamic conditions.The results revealed distinguished mechanisms for asphaltene solubilization/dispersion(such as hydrogen bonding,pep interaction and acid-base interaction)and influence of additional side group(OH)on inhibition power of inhibitor.During the experiments,it was found that increasing inhibitor concentration may lead to the self-assembly of inhibitor and declining of asphaltene stabilization.So,finding optimum concentration of inhibitor with high efficiency and available at a reasonable price is very important.The results suggest that 600 ppm of CTAB and 300 ppm of SDS were approximately optimum concentrations for the studied crude oils.One of the most important findings that differ from previous studies is the revelation of the mechanism behind the SDS/asphaltene behavior in various concentrations of inhibitor.Effect of chosen inhibitors on asphaltene precipitation and consequently deposition in porous media was studied,and then experimental data were modeled for evaluation of permeability impairment mechanisms.Permeability revived after inhibitor squeezing and cake formation mechanism played an important role in permeability reduction before and after treatment in porous media.The findings can also be applied to prediction of future behavior of reservoirs in oil field scale and evaluation of formation damage in the different period of production if needed any treatment process. | Mehdi Madhi Riyaz Kharrat Touba Hamoule | 2018 | Petroleum2018，4，2： | 7 |
| 2 | 基于瞬时产量递减分析确定天然裂缝性油藏平均地层压力显示文摘以Warren和Root等提出的裂缝-孔隙双重介质模型为基础,拓展延伸了Mavor、Cinco-Ley和Daprat等的裂缝系统拟稳态-定产量生产的解及基质系统拟稳态-定压力生产的解,提出了根据天然裂缝性油藏定压开采的瞬时产量递减准确估算油藏平均压力的新方法。具体方法为:分别将基质产量方程和裂缝产量方程两端取自然对数,得到两条直线;再利用其斜率和截距确定弹性储容比、油藏总储容以及泄油面积,最后确定平均地层压力。经算例和实例验证,新方法简单实用,与物质平衡法和Tiab直接合成技术法得到的估算结果十分接近。 | Daryasafar Amin Amareh Iman Fathi Nasab Mohammad Kharrat Riyaz Jalilian Milad | 2015 | 石油勘探与开发2015，42，2： | 5 |

| 11 | Microsponge based drug delivery system for augmented gastroparesis therapy:Formulation development and evaluation显示文摘The intention behind the present work was to develop a microsponge based novel dosage form for sustained delivery of domperidone.Quasi-emulsion solvent diffusion method was employed using Eudragit RS-100 with various drug-polymer ratios for the preparation of microsponges.For optimization purposes,several factors which affect microparticles’physical properties were investigated.Characterization techniques followed for the formed microsponges were DSC,FTIR,SEM,XRD and particle size analysis,along with morphology,drug loading and in vitro drug release.It was found that there were no chemical interactions between drugs and polymers used as per DSC and FTIR results.The drug-polymer ratio showed remarkable impact on drug content,encapsulation efficiency and particle size.SEM micrographs revealed that microsponges were spherical in shape with porous surface,and had 104±0.22μm mean particle size.The microsponges were then loaded in capsules followed by in vitro drug release study;which depicted that microsponges with drug-polymer ratio of 1:2 were more proficient to give extended drug release of 76.38%at the end of 8 h,superior in contrast to conventional marketed formulation Domstal®,which got exhausted incredibly earlier by releasing 82.57%drug at the end of 1⁄2 h only.Hence,the developed microsponge based formulation of domperidone would be an expectant,promising substitute to conventional therapy of gastroparesis,emesis and alike gastric ailments. | Riyaz Ali M.Osmani Nagesh H.Aloorkar Bharati U.Thaware Parthasarathi K.Kulkarni Afrasim Moin Umme Hani Atul Srivastava Rohit R.Bhosale | 2015 | Asian Journal of Pharmaceutical Sciences2015，10，5： | 1 |
