The fundamentals of scaling during waterflooding an oilfield are presented. Mineral precipitation is described using both the kinetics approach, with corresponding equations given, and thermodynamic models’ theoretical foundation discussed—mainly specific ion interaction Pitzer models. This paper focuses on process mixing incompatible waters water injection production from oilfield, as this was...

fractures are considered as one of the important structures in fractured reservoirs due to their effect on fluid currents and reservoirparameters such as porosity and permeability. fracture parameters can only be directly calculated with core and image logs. cores haveserious limitations, so image logs are the best method. the aim of this study is the systematic fractures analysis of the asmari...

The compatibility of the dimensions polymer molecular aggregates and pore throat reservoir were studied. W section Tuha oilfield was study area polymers produced by Daqing Refining Chemical Company used. permeability limit molecules with different masses concentrations, matching relationship between dimension obtained experiments. results research are important for development implementation a ...

This study deals with onshore oilfield drilling fluid system to drill corrosion. Corrosion under static and dynamic conditions of the drilling fluid was evaluated. The effect of temperature and pressure on corrosion was examined. Corrosion was more severely affected by temperature compared to pressure. The combined effect of a deoxidizing agent and an inhibitor was observed to exhibit better pr...

knowledge of the orientation of horizontal in situ stresses is important to some areas of oil and gas field development plans. borehole breakouts observed in image logs and drilling-induced fractures are the main parameters for the determination of the stresses’ directions in situ. in this work, the orientations of borehole breakouts were investigated as a function of depth in oil wells a and b...

Since 2006 wastewater has been injected below the Val d'Agri Quaternary basin, the largest on-land oilfield in Europe, inducing micro-seismicity in the proximity of a high-rate injection well. In this study, we have the rare opportunity to revise a massive set of 2D/3D seismic and deep borehole data in order to investigate the relationship between the active faults that bound the basin and the ...

A Oilfield is Fluvial Facies Low Permeable Reservoir, main layer bend distributary channel sand body deposition, In order to better understand the distribution of single and remaining oil in reservoir, inspection well coring tracer tests have been carried out successively same area oilfield, based on these data, it found that, actual very different from original description both vertical plane....

Khush Mittal I read the paper by Chi et al. with interest. The authors found a greater hypoxia response gene expression in carcinomas than stromal cells grown in vitro, but were not sure of the underlying explanation (see Discussion in [1]). The underlying explanation may be the difference in mitotic activity and hence metabolic activity between these two cell types, such that hypoxia may be pr...
