Abstract:
Fort Abbas concession is part of Punjab Platform which is a gentle eastward
monoclinal rise at the central Indus Basin. Seismic lines 944-FABS-42, 944-FABS-
43, 944-FABS-48 and 944-FABS-49 shot by OGDCL in year 1994 in Fort Abbas
area, were obtained from DGPC. The seismic lines under study area are dip and strike
lines. Seismic lines 944-FABS-42 and 944-FABS-43 are strike while 944-FABS-48
and 944-FABS-49 are dip lines. Drilling of Fort Abbas well No. 01 was carried out to
test the hydrocarbon potentials of Kussak and Khewra (Cambrian) and Salt Range
Formation of Pre-Cambrian. Three prominent reflectors namely Sui Main Limestone,
Lower Goru and Chiltan Limestone were marked on the seismic sections on the basis
of depth and velocity information of these formations. Time contour maps of the
reflectors were produced using two way time of the reflectors. Average velocities
were used to find the depths of the formations for the seismic section. Based on these
seismic maps the structure of the area was interpreted as a gently dipping broad
monocline.
