"Past experience of shale oil and shale gas suggests that these resource estimates are likely to be revised upwards significantly over time."
If the Organization of Petroleum Exporting Countries cuts production in response to the extra supply, oil prices will fall to around $100 per barrel in today's money by 2035, the report said.
If OPEC does not cut production, oil could fall to around $83 per barrel in today's money by 2035, PwC estimated, or $50 less than the EIA's 2035 real-terms forecast price of $133.
Brent crude oil is currently trading around $119 per barrel.
Lower oil prices will feed into stronger GDP growth, adding $1.7-$2.7 trillion per year, or $230-$370 per person, PwC said.
The level of support will vary greatly, however, from country to country, it said.
