Abstract This paper investigates cracking failure of the casing tube. There were longitudinal cracks in heavy oil thermal recovery well occurred an field. The fracture cause was analyzed by macrographic observation, chemical composition analysis, mechanical property test, metallographic scanning electron microscope (SEM) and residual stress calculation. results showed that crack failed originat...

Introduction There are three major oil sand areas in Canada, all in Alberta. There is also an oil sand deposit on Melville Island in the Arctic. The three major oil sand areas are from highest to lowest volume of reserves-in-place (AEUB 2003) Athabasca, Cold Lake and Peace River oil sand areas notwithstanding that bitumen reserves are also evident in subcropping carbonate rocks in Athabasca and...

in this paper, a simplified formulation for compositional reservoir simulator is presented. these types of simulators are used when inter-phase mass transfer depends on phase composition as well as pressure. the procedure for solving compositional model equations is completely described. for equilibrium calculation, property estimation peng robinson equation of state is used. this equation was ...

recently, a renewed interest arises in the application of nanotechnology for the upstream petroleum industry. in particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening the sand consolidation, reducing the inter-facial tension and...
