Which is a Pure play company in oil industry?
Frontier Oil Co, Continental Resources, ExxonMobil and Plains
All American can all be considered to fall within the "Oil
Industry" but to be a little more helpful, one should decide on
which component of the oil industry to focus on i.e refiners,
drilling/exploration/production, pipeline/transportation/marketing,
or fully integrated oil companies.
The above examples would fall into these more specific classes
of oil companies as follows:
Pure Play Refiner: Frontier Oil Company
Pure Play Driller/Producer: Continental Resources
Pure Play Tranporter/Pipeliner : Plains All American
Pure Play fully integrated oil company: ExxonMobil
