Figure 4.18A. The play resource distributions for the two windows are
shown in Figure 4.18B. The 0.9 probability prediction intervals for the
time windows of each play are similar.
Remarks
Assessment results are controlled by two factors: the quality of the
pool reserves booked at the time of assessment and the number of discoveries available for the assessment. Gas and oil pool appreciation

windows. (B) Play resource distributions for the pools from each time window
after evaluation by LDSCV displayed as upper 95th percentile (lower end),
