Low-salinity brine injection has emerged as a promising, cost-effective improved oil recovery (IOR) method for waterflooding reservoirs. Laboratory tests and field applications show that low-salinity waterflooding could lead to significant reduction of residual oil saturation. There has been a growing interest with an increasing number of low-salinity waterflooding studies. However, there are f...
پیشنهاد های زیادی توسط محققین برای کاهش انتشار دی اکسید کربن مطرح و اجرا شده است . یکی از بهترین روش ها، ذخیره سازی در ساختار های زمین شناختی زیر زمینی می باشد. ذخیره سازی وتزریق دی اکسید کربن در مخازن خالی نفت و گاز ، مخازن نفت و گاز برای eor و egr ،سفره های آب شور ، بستر های زغال سنگی و اقیانوس ها انجام می گیرد.کشور ایران دارای سازند های بزرگ نفتی و گازی می باشد.از این رو می توان از آن ها برا...
The ever-increasing demand for energy in our society calls for more efficient andsustainable recovery of fossil fuels. Enhanced Oil Recovery (EOR) deals with im-proving the recovery of oil from reservoirs. It encompasses not only the large-scaleengineering enterprise, but also the fundamental understanding and discovery ofthe relevant physicochemical processes. The motivation fo...
In oil production waterflooding is a popular recovery technology, which involves the injection of water into an oil reservoir. Studies on model-based dynamic optimization of waterflooding strategies have demonstrated that there is a significant potential to increase lifecycle performance, measured in Net Present Value. However, in these studies the complementary desire of oil companies to maxim...
The paper presents the effect of trapped gas during the application of secondary processes, or more precisely, in the period of application of conventional waterflooding of partially depleted oil reservoirs. These processes can be simulated by analogous tests on reservoir rock samples, on synthetic models under laboratory conditions or by numerical models. An explanation of physical mechanisms ...
At the conclusion of flooding in an oilor gas-bearing reservoir, a significant fraction of the original hydrocarbon in place remains in the swept region as trapped residual phase. In addition to the amount of trapped phase, its microscopic distribution within the pore space of a reservoir rock is important to gain a better understanding of recovery mechanisms and for the design and implementati...
Abstract To explore the flow mechanism of micro-remaining oil during cyclic waterflooding in low-permeability reservoir, displacement effect under conventional and different rounds was investigated by using a micro-visual experiment based on microfluidics model. The produced ratio types micro remaining quantified, major oils that can be applied effectively were analyzed. Moreover, investigated....
Reservoir wettability is determined by complex interface boundary conditions acting within the pore space of sedimentary rocks. These conditions have a dominant effect on interface movement and associated oil displacement. Wettability is a significant issue in multiphase flow problems ranging from oil migration from source rocks to such enhanced recovery processes as alkaline flooding or altern...
In this paper, the effect of flow rate on relative permeability curves was investigated in Iranian carbonate rocks. Core samples were prepared from outcrop of Asmari formation. The dynamic displacement experiments were performed at 2.55, 3.55, 4.55 and 5.55 cc/hr during waterflooding and oilflooding. Relative permeabilities have been calculated with the Jones and Roszelle method and then the fl...
