Title: Seismic data interpretation digitising scanner
Inventor: BRANSON RICHARD
IPC: G01V1/32
Filed: 1990-10-05
Abstract: An automated scanner for the digitisation of interpreted data on seismic sections, comprising a powered document transport system, a computer processing unit (C.P.U.) 42, and a scanner head 32 consisting of a linear illuminator 12 and sensor elements 14. The data interpretations are drawn on a seismic section 10 using ultra-violet sensitive wax crayon pencils, and the section is transported beneath the scanner head where the wax is illuminated by ultra-violet light and ultraviolet fluorescence is detected by the sensor elements. A single scan of the seismic section will therefore detect all interpretations on the section. The data are then processed by the C.P.U. and converted into digital signals, which are transferred to external computer devices for further data processing or stored internally. <IMAGE>
