many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...

Several countries, including Canada, contain sizeable bitumen resources in highly fractured carbonate rocks. Any possible recovery of bitumen from these reservoirs will be highly dependent on proper understanding of the rock and fluid properties and how they vary in the reservoir. These carbonates are extremely heterogeneous, and as a result proper reservoir characterization is challenging. In ...

conclusions the widespread distribution of l. major parasites in human suggests not only t. indica was the main reservoir but also other rodents and mammalian hosts might be the reservoir hosts of zcl in the region. molecular and phylogenetic analyses confirmed the strength of haplotype variation maintaining the circulation of leishmania species in their reservoir hosts. results leishmania majo...
