Thermal 15 was drilled in November, 1983, to a TD of 700 feet. A steam entry encountered at 490 feet was found to communicate with the highpermeability upflow zone of the Thermal Shallow Reservoir. A low-flowrate, higher-pressure steam entry at 600 feet was not detected while drilling but was indicated during a subsequent spinner survey. The pressure, flowrate, and enthalpy of the five wells co...

Xu deep volcanic gas reservoir is typical of complex lithology, severe inhomogeneity, big difficulty to extract. Pressure sensitivity always exists in gas reservoirs. Prorating production is too high or low, causing problems, as for the energy loss, reservoir damage, bottom effusion, thus lowing the gas productivity and affecting development benefit. So it have to research on a new reasonably p...

OBJECTIVE To determine the usefulness of a separate reservoir placed at the site of the shunt in evaluation of shunt malfunction. METHODS AND MATERIALS A ventricular catheter was placed alongside the proximal catheter of the shunt and connected to a subgaleal reservoir in 17 patients, in 9 a double-lumen catheter with integrated reservoir and in 13 patients a dual catheter with a double-port ...

INTRODUCTION Disposable manual resuscitators are commonly used to ventilate patients during cardiopulmonary resuscitation, suctioning, and intrahospital transport, and their clinical performance is critical. METHODS We bench-tested 16 adult disposable manual resuscitators from 9 different manufacturers. We performed a series of tests and made observations using testing industry standards as a...

Wave separation analysis and wave intensity analysis (WIA) use (aortic) pressure and flow to separate them in their forward and backward (reflected) waves. While wave separation analysis uses measured pressure and flow, WIA uses their derivatives. Because differentiation emphasizes rapid changes, WIA suppresses slow (diastolic) fluctuations of the waves and renders diastole a seemingly wave-fre...

Three dimensional (3D) printing technology is rapidly evolving such that printing speed is now a crucial factor in technological developments and future applications. For printing heads based on the inkjet concept, the number of nozzles on the print head is a limiting factor of printing speed. This paper offers a method to practically increase the number of nozzles unlimitedly, and thus to dram...

population growth can greatly impact on greenhouse gas emission pattern in the future. considering the importance of population growth in climate change studies, the present research concentrates on the population growth of the middle east in the late 21th century based on the iiasa population scenarios. under the projections of a1-b1 scenario, the world’s population will grow up to 8.7 billion...

The need for numerical models to simulate geothermal pressure transients has been long recognised. In the last few years various studies have used the TOUGH2 reservoir simulator to model different well tests, in each case with a different model setup. Important features such as the skin effect and wellbore storage are incorporated differently or are sometimes not present. Rarely is the model se...

The reservoir-induced seismicity (RIS) at the Karkheh dam site with a reservoir capacity of about 7.4x109 meters is investigated. Based on the assessment of the seismicity of the dam site in equal time periods before and after reservoir impoundment, it was found that the number of earthquakes have been tripled after impoundment, while their magnitudes and focal depths become smaller. The averag...

The main purpose of this investigation is to study the effect of near miscible CO2 injection in different porous mediums on both lab and field scales. This effect can be traced by the change of two-phase gas-oil relative permeability curves. In this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...
