Supply/Price Dynamics of Unconventional Petroleum Production
Oil prices more than tripled in the last decade, yet crude oil supply increased by only 7%
Old Price Norm
New PriceNorm
Horizontal Drilling and Hydraulic Fracturing is the only reason that both US oil & gas
production are not in decline
Production Costs – Marginal Oil Supply
Fantazzini, et al. Global marginal cost of production 2008. Source: LCM Research based on Booz Allen/IEA data (Morse, 2009).

Shale and tight reservoir plays are ‘high-hanging fruit’•Disseminated oil and gas, i.e. not concentrated
•Low permeability - the petroleum doesn’t flow
•Rock must be ‘stimulated’ to release the HCs
•Well production rates are much lower than conventional reservoirs
•Ultimate recovery much lower than conventional reservoirs (2-8% v 35-40% of original oil in place)
•Decline rates are much steeper
Market Dynamics
•Dry gas drilling in US largely uneconomic at recent prices of $2 - $4 MMbtu. Glut keeps price down.
•Rigs switching to oil and ‘wet gas’ with NGLs
•Power plants switch from coal to gas around $4
•US nat gas prices (<$4) is less than ½ Europe’s price ($10-$12) and ¼ of Asia’s ($15-18)
•Pressure for LNG export terminals
Supply/Demand Balance is Resolved by Price•Price is set at the margins
•FLOOR: Cost to produce the next barrel or mcf Oil: Deepwater ? Tar Sands ? Shale Oil? Gas: Horizontal drilling, fracking, water, regs
•CEILING: Price the marginal consumer is willing to pay for an additional barrel.
•What price will the Seller/Exporter accept? Can decide to leave in ground for the future
