4 Q B A multi-faceted instrumentation approach is described which has played a significant role in ob*ing fundamental data for two-phase flow model development. This experimental work supports the development of a three-dimensional, two-fluid, four field computational analysis capability. The god of this development is to utilize mechanistic models and fundamental understanding rather than rely...
Petroleum resources are found within sedimentary rocks that have a sufficient interconnected void space to store and transmit fluids. The actual flow of liquid and gas phases occurs on a micrometer scale in the void space between rock grains. On the other hand, the hydrocarbon is typically carried in rock zones that are a few tens of meters thick but extend several kilometers in the lateral dir...
Introduction To enhance slower arterial flow as well as faster flow without increasing imaging time, we have proposed a new MRA technique named hybrid of opposite-contrast MRA (HOP-MRA) that combined standard TOF white-blood (WB) MRA with the flow-sensitive black-blood (FSBB) sequence, resulting in excellent visualization of slow-flow vessels, as compared to the MTC-TOF MRA technique [1,2]. How...
This work shows the observed changes in sample permeability and fracture geometry that occur within a fractured piece of low permeability shale with different effective stress gradients applied to the plug sample. These observations were made using an in-situ micro-CT fluid flow imaging apparatus with a carbon fibre Hassler-type core holder. Changes within the preferential fluid flow path under...
The effects of aggregate characteristics on flow ability of mortar mixtures were investigated. Two types, five single sizes, and three gradations of fine aggregate were considered. Uncompacted voids of the aggregates were measured. Flow properties of 166 mortar batches made with the aggregates, together with different sand-to-cement ratios (s/c) and water-to-cement ratios (w/c), were evaluated ...
در حالت کلی معادلات حاکم بر یک مدل ریاضی از مخزن را نمی توان بوسیله روشهای تحلیلی حل کرد، در حالیکه یک مدل عددی می تواند بوسیله کامپیوتر جوابی تقریبی ارائه دهد. در این پایان نامه، یک دستگاه معادلات دیفرانسیل معمولی توسط گسسته-سازی معادله حاکم بر جریان شعاعی تک فازی نفت بسمت یک چاه (معادله چاه آزمایی) به دست آمده است. این سیستم شامل محاسبه تابع ماتریسی (exp(ka است که در آن k گام زمانی و a ماتریس...
