Title: Use of Seislog for Basin Evaluation and Previous HitFieldNext Hit Development: ABSTRACT

Author(s): R. C. Mummery

Article Type: Meeting abstract


Generation of synthetic sonic logs (Seislogs) from seismic Previous HitdataNext Hit can provide lithologic, porosity, and fluid-content identifications in a variety of

geologic settings. Case studies illustrate the type of information that can be extracted from seismic Previous HitdataNext Hit on carbonate rocks, including North Sea chalk, fractured limestones in Venezuela, and porosity development in regional limestones of western Canada. In the North Sea, 2 adjacent structures that appear similar on conventional seismic sections display porosity development and fluid content changes within the chalk reservoir on the Seislog section. In a South American Previous HitexampleNext Hit, the Seislog display demonstrates the ability of seismic Previous HitdataNext Hit to locate vertical fracture zones. In western Canada, secondary porosity development within Devonian carbonates was identified on Seislog displays, which led to the extension of a gas Previous HitfieldNext Hit. Examples from southeast Asia display a variety of depositio al environments in Miocene sediments. Shallow-marine and shoreline sands can be identified in a Malaysian Previous HitexampleNext Hit. An Previous HitexampleNext Hit from the Natuna Sea displays a lower delta-plain setting, with regional shale markers and thick clastic packages. An upper delta-plain Previous HitexampleTop (Gulf of Thailand) displays more faulting, expansion of clastic packages, and discontinuous channel sands.
