reservior engineering answer a b and c

Saga oil field's initial reservoir pressure is 3300 psia and the cumulative produced GOR at 2750psia is 1100SCF/STB. This field also has reservoir temperature of 250F and the standard conditions is 14psia and 61F. The PVT data are as illustrated in Figure 1 and Figure 2. Based on the provided data, estimate: (a) The recovery factor at 2750psia, if the reservoir exhibits only volume depletion (compaction drive). (b) The initial oil in place and recovery factor if the cumulative oil production at 2750 psia is 53 MSTB, the volume of water encroachment at 2750 psia is 55Mbbl, the cumulative water production at 2750psia is 35.3MSTB, and the water formation volume factor is 1.34bbl/STB. (c) Comparing the recovery factor from (a) and (b), what can be analyse
