A set of seismic track data and accompanying interpretations in XGEO proprietary format. All of the data are project based and are commercially obtained. The interpretations and track data are confidential to the customer. Track data is digitised from maps and charts and combined with digitised seismic profile data interpreted by the geologist. Data are held by project and by user id. All project based datasets are complete but these data are not available to users except where explicit permission has been sought from the data supplier. Seismic track data is usually sampled at every 10th shotpoint. This represents a sampling interval of 250m. The seismic sections will have limits in two way time up to 10 seconds. Data is presented to UKOOA and SEQ standards in terms of data formats. There is a low level of consistency in reflector nomenclature inter-project but totally consistent intra-project.
