These levels were built based on an assumption of increasing exploitation costs.

    Anticipation

    The oil and natural gas supply curve in the COFFEE model were built based on several studies. The data was obtained from detailed resource assessments in the engineering literature, detailed technical and cost parameters (such as Enhanced Oil Recovery, or EOR, recovery rates and potential) are available in 123. Data were gathered processed and compiled to determine the supply curve, as shown in Figure 1 and Figure 2.

    A coal resource assessment profile was also developed to check this availability. In the model, the categories defined for coal are betuminous, sub-betuminous, and lignite, all of them split in surface or mining availability for each region. Main sources for developing a specific supply curve include 2 and other related literature that was used to the estimate the methane content for every coal resource category (Figure 3).
