Abstract

Seismic stratigraphical interpretation of rock deposits has been done using migrated 3D seismic data in SEGY format. This has taken into consideration the analysis of both seismic sequences and seismic facies within the hydrocarbon reservoir of the Dongian oil block, North-east China. Methods adopted include that which identifies contacts of the upper and lower boundaries of the depositional sequences that were not absolutely correlatable. The style of the reflection patterns is discovered to be borne out of the very chaotic and dipping basement rocks. This is responsible for the arrangements of the overlying sequences which were continuous or truncated either on the basement or by the gently dipping listric fault amidst the middle portion of the sequences. In all two unconformities were observed. It was discovered that sequence 1 is the prolific reservoir and the overlying sequence 2 characterized by the sub-parallel to sigmoidal internal reflection pattern is a combination of reservoir and the seal that impedes hydrocarbon migration and makes the trapping system effective
