In many oil-recovery systems, relative permeabilities (kr) are essential flow factors that affect fluid dispersion and output from petroleum resources. Traditionally, taking rock samples the reservoir performing suitable laboratory studies is required to get these crucial properties. Despite fact kr a function of saturation, it now well established pore shape distribution, absolute permeability...

We present a case from a running series of inflatable penile prosthesis failure due to improper folding of the Conceal™ reservoir. The Conceal™ Low-Profile reservoir gained popularity due to claims of improved cosmesis and ease of implantation. As the number of patients receiving this and other low-profile reservoirs increases, it is imperative to review and document any novel complications. Wh...

in this study, a one-dimensional model called dyresm was used to simulate the thermal structure and artificial destratification of 15-khordad reservoir over a period of one year. the simulation showed that the reservoir is warm monomictic and is stratified during 210 days of the simulation year. the model reproduced the temperature of the meta- and hypolimnion very close to the observed data, b...

We present the results of a combined experimental and numerical investigation of the coalescence of a drop with a liquid reservoir of a miscible but distinct fluid. Particular attention is given to elucidating the influence on the coalescence process of a surface tension difference between drop and reservoir. Drops are gently deposited on the surface of the reservoir, and so coalesce with negli...

Igneous intrusions in sedimentary basins can influence basin-scale fluid flow and petroleum systems various ways. They may act as barriers, preferential pathways or even reservoirs for fluids. The fracture networks of usually represent the main control their hydraulic properties. However, our understanding different fracturing mechanisms quantitative effect on network properties remains limited...

High frequency (8-15 KHz) seismic waves that travel between two boreholes are used to probe the detailed structure of rock in the Los Alamos Scientific Labora:ory Fenton Hill geothermal energy reservoir. Because of the unique ability to control fluid pressure in the reservoir, we can make in situ seismic measurements at different fluid pressures and apply the results of pertinent laboratory mea...

In reservoir history matching or data assimilation, dynamic data such as production rates and pressures are used to constrain reservoir models and to update model parameters. As such, even if under certain conceptualization the model parameters do not vary with time, the estimate of such parameters may change with the available observations and thus with time. In reality, the production process...

This paper discusses noise generation mechanisms and techniques for noise reduction in fluid power units. Major noise sources in fluid power units can be identified with a sound intensity method. It has been proved that components of power units with larger sound radiating surfaces such as an electric motor and an oil reservoir produce a major part of global noise radiation.

productivity of an oil well is an important parameter in any oil field development. low production rate of the wells, impose more production wells drilling which directly jeopardizes the economical feasibility of the project. oil production rate in some of the wells is very low due to low permeability of the reservoir rock. several practice like hydraulic fracturing and acid fracturing is very ...
