We consider a situation where a thin liquid film is driven from a reservoir up a substrate by a thermally induced Marangoni shear stress and investigate the meniscus that connects the film with the reservoir, as well as the wave dynamics near the contact-line. We identify two types of meniscus solutions, and show, via a phase space investigation of the third order ODE that governs the profile, ...

An emerging method to increase the recovery from oil reservoirs is the application of measurement and control techniques to better control subsurface flow over the life of the reservoir. In particular the use of sensors and remotely controllable valves in wells and at surface, in combination with large-scale subsurface flow models is promising. Various elements from process control may play a r...

Numerical reservoir simulation models are used in the energy industry to forecast the behavior of hydrocarbon reservoirs and connected surface facilities over long production periods. The simulation of oil and gas reservoirs requires the construction and solution of large, sparse linear systems with millions or tens of millions of unknowns at each step of a Newton iteration. The problem size an...

The objective of this research is to study plant layout of NCRM (Narrow cold rolling mill division) of Bhushan steels Ltd. Mumbai based on the systematic layout planning pattern theory (SLP) for increased productivity. In this case study, amount of equipments and tools in rolling coil production are studied. The detailed study of the plant layout such as operation process chart, flow of materia...

In seismic interpretation with fluid flow simulation, we construct simple reservoir models with a small number of flow units, such as geologic layers and fault blocks. We call these units tanks and connect them with tubes. For such simple models, we may interactively adjust reservoir properties, such as porosities of tanks and transmissibilities of tubes. Numerical experiments suggest that para...

It is well known that reservoir simulation studies are very subjective and vary from simulator to simulator. While SPE benchmarking has helped accept differences in predicting petroleum reservoir performance, there has been no scientific explanation behind the variability that has frustrated many policy makers and operations managers and puzzled scientists and engineers. In a recent book by the...

background: taking visual acuity is an important part of an eye routine examination. this study was conducted to compare visual acuity measured using an iranian digital tumbling e chart with visual acuity measured using an italian digital tumbling e chart as a familiar foreign chart. materials and methods: this study was carried out on 200 participants (400 eyes; healthy n=40, glaucoma n=40, re...

Multiphase flows are commonly encountered in oil and gas industries. The transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the Baker chart. The effects of small downward inclinations of ...

abstract. in recent years several studies have shown that  control charts with adaptive schemes or double sampling plans detect both small and moderate shifts in the process mean more quickly than the traditional shewhart  chart. in the classical double sampling  chart, the difference between two points were placed in the central region of first stage was not considered. in this study, a new co...

The purpose of this study is the detection of lateral and vertical gradients of relative concentrations of compounds presented in oil. In addition, the detection allows us to assess potential drainage zones in a reservoir during the reservoir production by steam injection. In this paper, a new method for monitoring of steam chamber development in a 2D model was created and tested. The methodol...
