Abstract: 3-D Shallow Water and Transition Zone Seismic Acquisition Gets Results and Production in A Severely Demanding Environment

Oil companies and acquisition contractors both recognize the problems of acquiring cost effective 3-D seismic in the areas between where the land crew finishes and the deep water vessel begins. These areas, known as Transition Zones, often produce problems with data quality and production rate.

An acquisition crew has overcome these problems by using the Aram recording system. The combined experience of both the seismic crew and equipment manufacturer allowed for the successful completion of a 403 square kilometer 3-D survey in Sumatra, Indonesia. The 3-D survey was carried out in one of the harshest environments of its kind in the world.

Shown in the poster paper will be:
1) Before and After seismic sections
2) Satellite images of the area showing the land, transition zone area and deep water marine areas
3) Preplot projections of the survey
4) Numerous field photos of the seismic acquisition project showing the various types of terrain and environment
5) Testimonials about the quality of the data and acquisition planning and execution.
