An emerging method to increase the recovery of oil from subsurface reservoirs is the application of measurement and control techniques to better control the multiphase flow in the reservoir over the entire production period. In particular the use of sensors and remotely controllable valves in wells and at surface, in combination with large-scale reservoir flow models is promising. Various eleme...

The objective of this research is to study plant layout of iron manufacturing based on the systematic layout planning pattern theory (SLP) for increased productivity. In this case study, amount of equipments and tools in iron production are studied. The detailed study of the plant layout such as operation process chart, flow of material and activity relationship chart has been investigated. The...

State-of-the-art data analysis in production allows engineers to characterize reservoirs using production data. This saves companies large sums that should otherwise be spend on well testing and reservoir simulation and modeling. There are two shortcomings with today’s production data analysis: It needs bottom-hole or well-head pressure data in addition to data for rating reservoirs’ characteri...

Flow charts can be used to organize information, to describe a system, or to provide a framework for predictive calculations. At the least sophisticated level, a flow chart can be used to expose conceptual holes in our understanding of the relationships in a system. Such a chart need only be qualitative, though as the level of understanding increases and the recognized conceptual gaps occur at ...

The blood flow teas measured continuously in the intact vortex vein of the anesthetized rabbit using an ultrasonic Doppler -flowmeter toith a frequency response of approximately 4 Hz. Blood flow correlated well ivith perfusion pressure (arterial pressure minus intraocular pressure). The intraocidar pressure was changed stepwise by perfusion from a saline reservoir, Tonometry teas performed tuit...

The gas flow in shale matrix is of great research interests for optimized shale gas extraction. The gas flow in the nano-scale pore may fall in flow regimes such as viscous flow, slip flow and Knudsen diffusion. A 3-dimensional nano-scale pore network model was developed to simulate dynamic gas flow, and to describe the transient properties of flow regimes. The proposed pore network model accou...

Vacuum-assisted venous drainage (VAVD) is a technique used to increase venous return during cardiopulmonary bypass (CPB). However, VAVD has created some new safety concerns. One potential problem is the pressurization of the venous reservoir in the event of vacuum failure. To prevent this overpressurization, a positive pressure release valve (PPRV) is placed on the venous reservoir. The purpose...

This paper develops a system model for electrification in a flow loop and investigates volume charge accumulation due to recirculatory flow between a charge source and several charge relaxation regions. Enhanced charge densities are predicted when the source is a filter and the residence time in the relaxation regions is small compared to the liquid dielectric relaxation time. Small scale flow ...

Accurate integration of flow simulation and seismic modeling is one of the cornerstones of reliable time-lapse (4D) seismic monitoring. However, the question which scales flow simulations need to resolve to accurately capture reservoir changes during production and whether these scales are resolvable in seismic data is an open one. The answer impacts computational costs and our ability to predi...
