... was injected as a slug, oil recovery was similar to that with injection of just tetralin. Acceleration in oil production was observed for all the runs but was more pronounced with the presence of the catalyst. Both the tetralin and tetralin-catalyst runs showed a potential application to improve recovery...

... and viscous oils can be accelerated by the adequate use of downhole heaters that, by providing energy to the vicinity of the well, decrease oil viscosity and increase the oil production rate. A consequential advantage of using downhole heaters as a preamble to a steam injection process is that they accelerate...

Steam injection is more effective for heavy oil reservoirs, as for light oil reservoirs; there is the risk of fingering which results in production of steam without sufficient oil production. Even though, in literature, some authors have indicated that the steam...
