LAB 01 - SHOT NUMBER 12 to 15

​​In this section, displaying a group of seismic shot gathers concatenated together using the same function extracting_shots.m. I have extract shot gather number 12-15 where provided shot_num=12:15; in the following MATLAB code script.

MATLAB SCRIPT LAB 1.4

%% Assignment 1
load SeismicData_C.mat
Dg=D;
shot_num=12:15;
p=0;
[Dshot,dt,dx,t,offset]=extracting_shots(Dg,H,shot_num ,p);
scale=1;
​
%% Wiggle plotting
mwigb(Dshot,scale,offset,t)
xlabel('Offset(ft)','FontSize',14)
ylabel('Time(s)','FontSize',14)

Figure 1: wiggle plotting shot number 12 to 15

%% Gray scale plotting
figure,simage_display(Dshot,offset,t,0)
xlabel('Offset(ft)','FontSize',14)
ylabel('Time(s)','FontSize',14)

Figure 2: gray scaled variable density display shot no 12 to 15

%% Colored image plotting
figure,simage_display(Dshot,offset,t,1)
xlabel('Offset(ft)','FontSize',14)
ylabel('Time(s)','FontSize',14)

Figure 3: colored plotting image for shot gather no 12 to 15

Figure 4: wiggle on top of colored plotting image for shot gather no 12 to 15

From the image shown above, we can observe the existing of bad trace in shot number 12 that requires trace editing and muting.
