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...

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...

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...

Introduction: Leishmaniasis is a complex parasitic disease with various epidemiological and clinical features. Visceral leishmaniasis (VL) can be extremely fatal in untreated cases. The objective of this study was to assess the epidemiological and clinical aspects of the disease in children with VL in Kerman province during 1991-2006. Method: In a descriptive-analytical survey, medical file...

In the recent years, there has been an increasing rate of kala-azar disease in the south of Baft (Kerman/Iran). A survey on the records of admitted patients in the main hospital of Kerman city from 1993- 2003 showed that from the total of 36 cases of visceral Leishmaniasis, 12 cases (33/3%) were from south Baft. Since awareness of visceral Leishmaniasis vectors status has a key role in disease ...

In this study, seven walnut populations (Rabor, Hanza, Sardoueih, Dalfard, Bidkhan, Dehbakri, and Baft) were selected from Kerman province and compared for drought stress tolerance. Water potential between 0 and -1.5 MPa was obtained by polyethylene glycol 6000 solutions. Germination percentage, leaf relative water content (LRWC), and growth parameter of seedlings diminished with increasing dro...

background: cutaneous leishmaniasis constitutes a major public health problem in many parts of the world including iran. the primary objective of this study was to identify leishmania spe­cies in endemic districts of kerman province, south-eastern iran . methods: this study was conducted by random sampling as cross- sectional descriptive between 2008 and 2010. overall, 203 skin scraping smears ...

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...

Reservoir operation involves many critical decisions due to unpredicted circumstances, such as drought or flood. The reservoir water release decision is one of the challenging tasks for the reservoir operator since the decision to deal with many complicated decision variables and multipurpose operation. Typically, the water that flow into the reservoir comes from the upstream river network. The...
