in this work, the potential of auto-ignition of heavy oil during in-situ combustion (isc) process was studied. kinetic studies were carried out using thermo gravimetric analyzer (tga), differential scanning calorimetry (dsc) and accelerating rate calorimetric (arc) techniques. effects of oxygen partial pressure, reservoir pressure and clay on auto ignition condition were investigated on a numbe...

In this research attempts were made to estimate the in-situ stresses acting on a hydrocarbon reservoir based on routine activities of acid injection in oil reservoir. It was found that the relation between the re-opening pressure of fracture and principal in-situ stresses can be estimated using rock mechanics equations for the circular underground cavities. An appropriate relation between the m...

Dahuofang Reservoir is an important drinking water source for Shenyang, Fushun, Anshan, Liaoyang, and other cities. The quality of the upstream inflow river directly affects supply safety. When a sudden pollution accident occurs reservoir, risk to can be minimized if variation rule pollutant concentration along course accurately simulated in time. Therefore, based on Mike 21, this paper establi...

reservoir characterization plays an important role in different parts of an industrial project. the results from a reservoir characterization study give insight into rock and fluid properties which can optimize the choice of drilling locations and reduce risk and uncertainty. delineating hydrocarbon bearing zones within a reservoir is the main objective of any seismic reservoir characterization...

The chemical surfactant flooding can mobilize the trapped oil by lowering the interfacial tension between oil and brine and in some cases altering the reservoir rock wettability. In this work, the effect of surfactants on oil/brine interfacial tension was experimentally investigated. First, the effect of surfactants concentration was surveyed. Afterwards, the effect of salinity on surfactant be...

This study analyses the impact of climate change on inflows, sediment loads, and nutrient inputs to Sabalan dam reservoir, a warm monomictic lake located northwest Iran. For this purpose, Soil Water Assessment Tool (SWAT) was calibrated (2005–2018) validated (2001–2004). Future climate-based data under AR5 emission scenarios were obtained from HadGEM2–ES general circulation model then downscale...

Planning for supply water demands (drinkable and irrigation water demands) is a necessary problem. For this purpose, three subjects must be considered (optimization of water supply systems such as volume of reservoir dams, optimization of released water from reservoir and prediction of next droughts). For optimization of volume of reservoir dams, yield model is applied. Reliability of yield mod...

background: zoonotic cutaneous leishmaniasis (zcl) is a neglected disease with public health importance that is common in many rural areas of iran. in recent years, behavioral resistance and/or bait shyness against the common rodenticide among reservoir hosts of zcl have been reported. the aim of this study was to evaluate the effectiveness of klerat® and zinc phosphide against natural reservoi...

permeability is a key parameter in reservoir characterization. in fact, without accurate information about reservoir permeability, there is no good solution for reservoir engineering problems. up to now, permeability values of a reservoir have been calculated through laboratory measurements or well testing methods. these methods are useful but they cannot describe a reservoir reliably and preci...
