Pore-scale Simulation of Water Alternate Gas Injection
We use a three-dimensional mixed-wet random network model representing Berea sandstone to compute displacement paths and relative permeabilities for water alternating gas (WAG) flooding. First we reproduce cycles of water and gas injection observed in previously published experimental studies. We predict the measured oil, water and gas relative permeabilities accurately. We discuss the hysteres...
متن کاملAn Experimental Examination of Adsorption Phenomenon in Foamassisted Water Alternative Gas: The Effect of Injection Rate
The main factor affecting the economics of foam-assisted water alternative gas (FAWAG) process is the loss of foaming agent by adsorption onto reservoir rocks. In this study, the effects of phases, surfactant concentration, salinity, adsorbents, and sacrificial agent on adsorption density were investigated by special adsorption experiments. Moreover, a series of FAWAG tests were performed to ex...
متن کاملBlindness Due to Hyaluronic Acid Filler Injection: A Case Report and Review of Literature
Purpose: To Report a case of blindness due to hyaluronic acid filler injection. Case Report: A 28-year-old female patient was referred to our clinic with complaints of vision loss in the left eye, which occurred one hour after hyaluronic acid filler injection for correction of detachment trough hollowness. In the ophthalmologic examination, relative afferent pupillary defect (RAPD) was positive...
متن کاملMulticomponent mass transfer across water "lms during hydrocarbon gas injection
Understanding the dynamics of pore-scale multicomponent gas and oil mass transfer across water "lms during hydrocarbon gas injection in petroleum reservoirs is important in the design of tertiary oil recovery schemes at the "eld scale. The water "lms prevent oil and gas coming into direct contact and, for miscible gas injection, delay the onset of miscibility. We use a pore-scale model to descr...
متن کاملAn Experimental Study of CO2-low Salinity Water Alternating Gas Injection in Sandstone Heavy Oil Reservoirs
Several studies have shown that oil recovery significantly increased by low salinity water flooding (LSWF) in sandstones. However, mechanism of oil recovery improvement is still controversial. CO2 that develops buffer in presence of water is expected as a deterrent factor in LSWF efficiency based on mechanism of IFT reduction due to pH uprising. No bright evidence in literature suppo...
