Abstract:
Multi-channel reflection seismic data (MCS) were obtained by means of a 144-channel digital streamer (Hydroscience Technologies Inc.) with an active length of 600 m and a hydrophone-group interval of 4.167 m. The streamer was depth controlled by four navigator birds (Geospace Technologies) and towed at a water depth of 2 to 2.5 m. As seismic source, an array consisting of a standard GI gun and a mini GI gun was used with a total volume of 150+45 in3. The airguns shot with a pressure of 180 to 200 bar every 12.5 m or 16.7 m at a survey speed of 5 to 5.5 kn. Data were sampled with a rate of 1 ms and a record length of 4 s and were stored SEG-Y format. The profiles are fully processed and time migrated by the use of the Halliburton-Landmark ProMAX 2D software package.
