The result of burial history modeling from Well FA-SS-35-04 including TTI and
209 Ro data indicates that the source rock is mature in middle Mae Sod Formation
210 (Oligocene) below 5,900 feet and is over mature at lower Mae Sod formation
211 below 6,800 feet as shown in Figure 15-16. In conclusion the source rock were
212 mature and generate mainly oil at 5,600 – 6,700 feet. The source rock deeper than
213 6,700 feet were late mature and generate mainly gas.
