Mixed wettability develops naturally on a pore scale in oil reservoirs after primary drainage. The invading fills interiors that become oil-wet by asphaltene deposition, while the residual water retreats into corners, masking them and retaining their wetness. This alteration hinders mobilization during secondary waterflood. Therefore, proper understanding of conditions controlling pore-scale im...

In today’s competitive business and industrial environment, it is becoming more crucial than ever to assess precisely process losses due to noncompliance to customer specifications. To assess these losses, industry is extensively using Process Capability Indices for performance evaluation of their processes. Determination of the performance capability of a stable process using the standard proc...

industrial organizations are complex systems` where the interactions among the various functions such as sales, distribution, manufacturing, materials, finance, human resources and maintenance have to be man-aged towards a common purpose of delivering the customers satisfaction. however, since most of these or-ganizations have a `functional structure`, each function or department works towards ...

Pore-network models have been used to describe a wide range of properties from capillary pressure characteristics to interfacial area and mass transfer coefficients. The void space of a rock or soil is described as a network of pores connected by throats. The pores and throats are assigned some idealized geometry and rules are developed to determine the multiphase fluid configurations and trans...

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 study we analyze the effects of environmental performance on the generation of firm value from dow jones sustainability index europe. we use a sample of 122 firms from different sectors, except financial one, which belong to this index for the years 2007 through 2009. the expected results, taking into account our hypotheses, should show a positive relationship between the generation of ...

bioretention or rain garden is a preferable low impact development (lid) approach due to its characteristics which reflect natural water cycle processes. however, this system is still little understood and quite complicated in terms of design and implementation due to many technical considerations. hence, this paper gives a review of the challenges and developments for the use of bioretention f...
