Seismic reflection amplitude (dim spot) study over the Goodwyn Gas Field, North West Shelf, Australia

Abstract

A Seismic Reflection Amplitude study carried out over the Goodwyn Gas Field found that reflection amplitudes at the major erosional unconformity bounding the reservoir sequence could be directly related to the lithology and fluid content of the subcropping reservoirs. A colour coded amplitude map was generated and has been used for the prediction of lateral sand distribution/continuity within the reservoir units, both in the interpretations leading to the successful 1986 Goodwyn North appraisal drilling campaign and subsequently in planning for development of the field.
