More than 2 y have passed since the BP-Deepwater Horizon oil spill in the Gulf of Mexico, yet we still have little understanding of its ecological impacts. Examining effects of this oil spill will generate much-needed insight into how shoreline habitats and the valuable ecological services they provide (e.g., shoreline protection) are affected by and recover from large-scale disturbance. Here w...

With immense potential to enhance oil recovery, CO2 has been extensively used in the exploitation of unconventional tight reservoirs. Significant variations are observed occur oil’s composition as well its physical properties after interacting with CO2. To explore impacts on extraction efficiency, two different types crude (light and heavy oil) huff-n-puff experiments. Moreover, numerical simul...

The present work proposes for the first time a mathematical model for describing the rheological behavior of heavy and extra-heavy crude oils in the presence of nanoparticles. This model results from the combination of two existing mathematical models. The first one applies to the rheology of pseudoplastic substances, i.e., the Herschel-Bulkley model. The second one was previously developed by ...

a bacterial culture was isolated from oil-contaminated soil based on its ability to metabolize the quinoline as the sole source of nitrogen. in this research bacillus licheniformis strain was identified based on the result of 16s rrna analysis. optimized conditions were obtained with full factorial experimental design method using design expert software at temperature: 32oc, agitation speed: 20...
