DIVISIONS OF BAPEX
GEOPHYSICAL DIVISION AT A GLANCE
Geophysical Division has acquired 5024 line km of seismic data from 1989 to 2010. The data are processed in
Geophysical Data Processing Department and interpreted in Geophysical Interpretation Department under the Division.
Time and depth contour maps are prepared for interpretation. Geological settings are tried to match with the nearby wells of
the delineated structures. Location of exploratory or development wells are suggested from the division. Most onshore part of
the basin is explored seismically by the division, starting from single fold to multifold seismic, also gravity and magnetic data
taking under consideration. The division preserves all internal prepared reports. Coordinates of Geophone Position (GP) and Shot
Position (SP) recorded and filed. SEG-D and SEG-Y format data are also preserved in tape.

- Past Activity (before 1989) :
- Before forming BAPEX the division was under Petrobangla. From 1978, the division
started acquiring multifold seismic data. A total of 14,235 line km of 6/12/24-fold
seismic data were recorded, processed and interpreted by the division. Single fold analog
data of 6,642 line km were recorded from 1963-78 under Oil and Gas Development Corporation (OGDC) and then Petrobangla.
