The basal unit of Sequence 1 consists of a set of parallel and landward restricted reflectors (Figure 25). The GR log for this interval shows an upward increasing trend ending with a peak in basinward wells (F02-1 and F06-1), while the trend is questionable in well F03-4. Ending peak was interpreted as a maximum flooding surface (Figure 24). Based on the reflection terminations and the GR response, this unit is interpreted as a TST.The MFS records the deepest water facies within a sequence and marks the turnaround from transgression to normal regression. The MFS is commonly associated with sediment condensation or starvation. The TST is overlain by the second package, which shows prograding parasequence sets. This package shows dipping and prograding sigmoidal reflections that downlap onto the MFS (or downlapping surface; Figure 23). Thus, this package is interpreted as an HST which is landward restricted and contains normal regression deposits. Well logs for this interval are characterized by upward decreasing GR values. The package is bounded at the bottom by the MFS and at the top by both the subaerial unconformity (SU) and the basal surface of forced regression (BSFR). The SU is interpreted to be the result of both regional uplift and local uplift caused by Zechstein salt intrusion into the overlying sediments. The third package is characterized by offlap reflection terminations of a set of prograding clinoforms. This unit is confined to the basinward direction indicating a detached forced regressive unit (Figure 23). Therefore, this interval is interpreted as a falling stage systems tract. The FSST is bounded at the bottom by the BSFR and at the top by the SU and correlative conformity (CC). The CC corresponds to the end of forced regression. The BSFR corresponds to the seafloor at the onset of forced regression (De Bruin and Bouanga, 2007). The surface bounding the FSST at the top is interpreted as the first sequence boundary (SB). The FSST interval cannot be clearly identified in well logs; its interpretation is thus solely based on seismic geometries.
