Experimental Study of Foam Flooding in Low Permeability Sandstones: Effects of Rock Permeability and Microscopic Heterogeneity
Foam flooding (or injection of foam) is a common technology to enhance oil recovery. Although the effects of permeability on foam flooding were well studied in many laboratory experiments, little research has been focused on the specificity of low permeability. In this paper, a series of constant-quality nitrogen foam flow experiments were conducted to investigate the effects of permeability on...
متن کاملeffect of bataine and sulphate supplement on wool and milk characteristics and lambs performance in naine ewes
تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...
15 صفحه اولA Study on the Mechanism of Urea-assisted Steam Flooding in Heavy Oil Reservoirs
The Biqian-10 block, located in Henan Oilfield of Sinopic, contains many thin and interbedded reservoirs, which have been operated by cyclic steam stimulation for 20 years or more. Therefore, it is a challenge to implement the conventional steam flooding. In order to improve the recovery of steam flooding, urea was used to assist steam flooding. Urea can decompose into CO2 and NH3, which are be...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولA new investigation on modeling of permeability reduction during CO2 flooding processes in sandstone oil reservoirs
Permeability reduction in oil reservoirs during primary oil recovery and using the enhanced oil recovery methods are complicated problem which most of the oil field in worlds has encountered. In this work, a modified model based on four phase black oil model (oil, water, gas, and asphaltene) was developed to account permeability reduction during CO2 flooding in cylindrical coordinates around a ...
