in this research the experimental and theoretical studies on different enhanced oil recovery (eor) techniques, i.e. water flooding (wf), gas injection (gi) and water alternating gas process (wag) were performed on specimens taken from an iranian carbonate offshore reservoir at the reservoir condition. the experimental results for each specified techniques were compared with the corresponding re...

Aim. The aim of the research was to investigate induction Triticum aestivum L. non-specific tolerance by nicotinic acid hypoxia during flooding stress. Methods. Winter wheat plants cv. Ladyzhynka were grown in laboratory conditions and had been treated solution then stress started. hydrogen peroxide content leaves morphometric parameters measured experimental period. Results. It is shown that i...

prior to the implementation of co2 injection eor projects, the screening evaluation of candidate reservoirs will promote the economic benefits of co2 injection. currently, a uniform screening method for co2 miscible flooding does not exist. based on more than 112 successfully implemented co2 miscible flooding reservoirs, which was referred in 2010 worldwide eor survey, and co2 miscible flooding...

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...

The objective of this paper is to establish relationships between rainfall extremes and damage data from Dutch insurance industry. Rainfall data are based on a network of 33 automatic rain gauges held by the Royal Netherlands Meteorological Institute. Rainfall characteristics, such as peak rainfall intensity and rainfall volume, are correlated with damage statistics of claims in the vicinity of...

Soybean (Glycine max) is sensitive to flooding stress, and flood damage at the seedling stage is a barrier to growth. We constructed two mathematical models of the soybean metabolic network, a control model and a flooded model, from metabolic profiles in soybean plants. We simulated the metabolic profiles with perturbations before and after the flooding stimulus using the two models. We measure...

The mangrove plant Acanthus ilicifolius and its relative, mollis, have been previously proved to possess diverse pharmacological effects. Therefore, evaluating the differentially expressed proteins of these species under tidal flooding stress is essential fully exploit benefit from their medicinal values. roots A. mollis were exposed 6 h per day for 10 days. dry weight, hydrogen peroxide (H2O2)...

The waterlogging tolerance and the physiological responses to this stress were tested in seedlings of Fraxinus angustifolia, an ash tree inhabiting riparian forests, and two provenances of the closely related Fraxinus excelsior, one derived from a riparian forest (FER) and one from a mountainous region (FEM). Besides visible damage, physiological parameters reflecting adaptations of plants to w...

Rice bran application just after transplanting has been increasingly practiced as a herbicide-substitute for organic rice production in Korea. However, this practice is frequently reported to be unsatisfactory in weed suppression. An experiment with five treatments that combine flooding depth (shallow and deep), rice bran application level (low and high), and herbicide application was carried o...

This study sought to probe the role of input flooding through listening tasks on the uptake of simple present tense and the present progressive tense among pre - intermediate English a s Foreign Language ( EFL ) learners. To comply with the objective, an experimental design was adopted. 55 pre - intermediate learners participated in the study. They were randomly divided into one control group, ...
