Nowadays solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) have been investigated as carrier systems for many applications. SLNs consist of pure solid lipids, while NLCs are made of a solid matrix that entraps liquid lipid nano-compartments. These systems revealed several advantages compared to other colloidal carrier systems. They provide a controlled drug release and an ...

The vapor extraction (VAPEX) process, a solvent-based enhanced oil recovery process has been found promising for some heavy oil reservoirs. In this work, the VAPEX process is studied using a compositional simulator on a number of single-block and multiple block fractured systems. PVT data of one of an Iranian heavy oil reservoir are used to tune the equation of state. Effects of fracture sp...
