heavy oil
-
Thermal steam stimulation is considered the most effective of current methods for heavy-oil production. However, the method has problems with low coverage by steam injection and decreased efficiency. -
Chemical enhanced-oil-recovery methods such as polymer and alkaline/surfactant/polymer (ASP) flooding are generally not considered suitable for oil viscosities greater than 100 or 200 cp.
-
To sustain the current level of heavy-oil production, which comprises roughly 12–15% of total production, process efficiency must be enhanced to control costs.

Q&A to discuss heavy oil production and some of the challenges of working in harsh environments.
-
To support subsea processing of heavy crudes, an inline electrocoalescer was tested for separation of water droplets dispersed in the crude oil.

This paper presents data from both pilot tests and field tests of a recent burner retrofit of a horizontal heater treater at an oil sands field in northern Canada.
-
Europe’s largest onshore oil field, the Patos-Marinza in southern Albania, has been given a new lease on life after seeing production soar from 600 B/D just over a decade ago to more than 20,000 B/D this year.
-
With the decline in oil price and typical product differentials, the current year will be particularly challenging for heavy-oil operations.
-
Hybrid steam/solvent processes have gained importance as a thermal-recovery process for heavy oils in recent years.
