co2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. in this study, the lower part of es1 reservoirs in pucheng oilfield was introduced as the target reservoir. by studying the minimum miscible pressure in co2 flooding, the reservoir could achieve miscible flooding. long core displacement experiments prove...

In areas of flooding, soil bacteria could infect humans. We report a 78-year-old woman who developed Pseudomonas putida soft tissue infection associated with bacteremia after passing through the water of a flooded area. She recovered very well after a 14-day course of intravenous ceftazidime therapy. Physicians should be alert to soft tissue pseudomonae infection during the flooding season.

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 supports this id...

One of the methods to achieve optimal conditions in increasing oil recovery through injecting polymers is by optimizing parameters that influence success provide information and be considered when determining new schemes for implementation future. Optimization obtain optimum value factor best PV, injection rate, time, pressure, adsorption, residual resistance (RRF), inaccessible pore volume (IP...

Aim at the reservoir characteristics of Suizhong 36-1 Oil Field, this paper has developed typical twodimensional physical model in parallel between the layers and studied the macroscopic displacement effect of polymer flooding and binary compound flooding, and studied the interlayer spread law and oil displacement efficiency of polymer flooding and binary combination flooding by using saturatio...

introduction: water crisis as a majorlimitation factor for agriculture, like other arid and semiarid regions exists in isfahan province which is located in the central part of the zayandehrud river basin (zrb). rice appears to be the far-most profitable crop but at the same time it has a major impact on basin scale water resources, especially affecting downstream farmers. in the study area (sha...

The effect of flooding can be a serious problem for wheat farmers, even at dry land condition. Amount of flooding damage depends on duration flooding, developmental stage, wheat type and variety. Therefore as a factorial experiment in randomized complete design based on winter bread wheat cultivars (Pishtaz, Marvdasht, Shiraz, Zarin, Shahriar, C-81-4, Sardari, Agosta seed, FGS and Azar2) at sta...

The frequency of summer flood events has strongly increased in Eastern Europe during the last decades. The creation of water storage areas to avoid flooding is often combined with the recreation of more natural and biodiverse riverine systems. This urges the need to understand the consequences of summer inundation, when microbial activity is significantly higher than during winter inundation, f...
