Archiving 2-D and 3-D Seismic Data Sets

To support the OERA’s initiative to better understand the petroleum geoscience of offshore Nova Scotia, two seismic datasets have been transcribed, reprocessed and archived by Kelman Technologies Inc.  and are available for free at the Canada – Nova Scotia Offshore Petroleum Board’s Data Management Centre.

The datasets include 2-D and recon 3-D surveys acquired in 1985 and 1991, respectively. The two seismic datasets were acquired along the northern portion of the Jurassic Age carbonate bank to evaluate regional oil plays and the Penobscot structure on trend with and similar to the Cohasset, Balmoral and Panuke Oil Fields comprising the Cohasset Project. The Cohasset Project operated from 1992 to 1999 and produced a total of 7.1 million cubic metres (44.5 million barrels) of high quality oil. These digital datasets are the first ones available offshore Nova Scotia that can be loaded and fully interpreted on a geophysical workstation. The field data is also available so that as processing techniques improve, the data can be continuously enhanced and also allows for specialized processing to be done.

Reprocessing has improved the data dramatically thus improving the interpretability of the datasets allowing industry to evaluate new exploration opportunities over the northern portion of the Jurassic Age carbonate bank.
