Abstract: The Application of Seismic Attributes as a Predictive Tool to Optimize Gas Development at Lawit Field

Wan Zurushdi Muhammad, Abdul Khair Abdul Aziz

Geological Society of Malaysia (GSM)

Abstract: Seismic Processing of Ocean Bottom Cable and Streamer Data over Seligi Field

Lye Yue Choong, Abdul Razak Mohd Nurin

Geological Society of Malaysia (GSM)

... PHIFAR filter was applied to both the OBC and streamer data to dephase and convert the data into zero phase. OBC data were found to be very sensitive...
