Abstract:
This thesis is based on 2D seismic reflection data and well logs. The data is
acquired from the area of Khipro, Southern Indus Basin (Sindh) of Pakistan, provided
by the Landmark Resources (LMKR) with the permission of Directorate General of
Petroleum Concession (DGPC). Six seismic sections having line numbers along with
Base Map are 2000-KH-04, 2000-KH-08, 2000-KH-30, 2000-KH-35, 2000-KH-36
and 2000-KH-42. Out of these six seismic lines, five seismic lines; 2000-KH-04,
2000-KH-08, 2000-KH-30, 2000-KH-36 and 2000-KH-42 are dip lines. The
remaining line, 2000-KH-35 is a strike line. Root mean square and interval velocities
which were computed during processing are also provided with the seismic section at
selected Common Depth Points (CDPS) and are used for the calculation of average
velocities to convert the given time into depth.
Four reflectors were marked due to their prominent reflection on the seismic
sections. The two way travel time structural map for each reflector has been drawn
and depth contour map of probable reservoir has also been drawn by using velocity
and one way travel time. Moreover, Cross Sections in time and depth domains have
also been drawn. Normal faults exist in the area and the associated Horst and Graben
structures are observed along with Negative Flower structure and step faults.
By using well log data, petrophysical evaluation of Siraj South-1 shows the
characteristics of hydrocarbon bearing zone which confirms the results of the 2D
seismic interpretation.
