(a) Arbitrary seismic Inline; (b) Arbitrary seismic Xline (flattened by surface C), (c) Coherence slice (surface O3) display the typical seismic response characteristics of the Halahatang oilfield, which hinders the detection of strike-slip faults. The blue arrows indicate the karst valley. The pink ellipse and arrows indicate the bead-like reflection.
