## 4 Seismic Data Interpretation
The location of the Tola (1) well is added in the base map. The Tola (1) well is located at 875-KBR-230 line in the Base Map. Owing to the seismic data interpretation, four reflectors are defined in the seismic sections. The well tops of Tola-01 are utilized for the correlation. The horizons are the Dunghan, Samana Suk, Datta, and Warcha formations, as shown in Table 4. Similarly, the horizons of seismic lines are given in detail in Figures 3-7. The Tola (01) well is located on the 875-KBR-230 line in the base map. The 875-KBR-230 line is used as a reference for marking our seismic sections. The well tops of the Tola-01 well were used to locate the required reflectors on the seismic section. The well tops data give us the formation tops with a required depth. As far as the well tops of the Tola-01 well \begin{table}

The fit line curve created from the velocity windows calculation and the graph help us find the time against the depth on the time section. The time values of the prescribed formations have been obtained using the time depth chart. Then, these time values obtained from the time-depth chart of well Tola-01 were projected on the seismic line 844-KBR-230. Furthermore, a line is drawn from the prescribed shot point crossways on the seismic traces toward the second time vertically, and the values of the time are also pinpointed on the well line over the seismic line. The time picked on the seismic line is shown in Tables 4 and 5. For labeling the seismic horizons and faults, the time of each reflector will be recognized at various shot points, and the travel time of each reflector will be marked along with faults on the \(y\)-axis, in contrast to the shot points on the \(x\)-axis. In the present study, there are four marked reflectors with normal faults on each line. Gridding of these lines was assembled for a contouring plan as well as to interpret the configuration model of these lines for the arrangement of contouring. The horst along with the graben configurations that existed on the seismic sections (Figures 3-7) may be a proper vicinity for the gathering of hydrocarbons. Thus, the labeled seismic sections are the promoted sections of the reflectors, which point out the subsurface configurations in the time domain. The values of the time depth are taken on the seismic line 845-KBR-45. Therefore, the trace on a specific time, using the referred time scaling, is used to locate the time on the well spot. In addition, after four traces are marked, four of them are therefore spread, using the common line joining the trace. The trace is observed by watching it parallel to the paper orientation rather looking from the top. Then, the horizons are marked on the seismic line. The time contour maps of four horizons are organized and demonstrated in Figures 8a, 9a, 10a and 11a. The average stacking velocities are used to convert the two-way travel time (TWT) of these four horizons into depth at Tola-01, and the resulting depth structure maps are shown in Figures 12a, 13a, 14a and 15a. The seismic line 844-KBR-5, which is a strike line, was reserved as a control line for the correlation.
