SUBJECT : "RECENT ADVANCES IN ACQUISITION TECHNOLOGY"

ABSTRACT
3D seismic technologies have advanced rapidly during the 1990's. The new
generation of seismic vessels such as the Ramform design with their massive
towing capacities has changed the way in which modern seismic data is
acquired. This has resulted in a large increase worldwide in the use of 3D
seismic data during the exploration phase because of the reduction in the
cost of 3D data. A statistical data base has emerged showing that drilling
on 3D data will double the commercial success rate compared to drilling on
2D data.
Historically, dual-source acquisition has dominated exploration, by
comparison to single-source acquisition, due to cost savings associated with
the fact that single-source acquisition implies a geophysical requirement to
tow the streamers at half the separation of dual-source acquisition.
However, data quality associated with single-source acquisition is typically
much superior to dual-source data. The ability now to tow 12 - 16 streamers
has reduced costs so that single-source acquisition is now cost effective.
The surveys using single source acquisition allow 3D data to be acquired
with significantly higher trace densities and crew efficiencies than
industry standard. These High Density 3D or HD3D surveys have benefits of
increased fold, improved spatial resolution and improved imaging quality.
They can now be routinely conducted, especially in "difficult" data areas.
This talk will discuss HD3D showing examples as well as future ideas
relating to wide-azimuth overlapping recording to improve illumination of
structures and increase signal to noise ratios.
FUTURE TALKS
Suggestions and volunteers for talks are always welcome. Topics should be
relevant to exploration and production in Indonesia and/or be of interest to
a wide range of disciplines.
