Seismic Tiles - a New Way of Working with Seismic Data - 4D Examples

Abstract

Summary Seismic Tiles is a new way of digitalizing seismic reflector information. By representing the seismic data through small, rectangular surfaces that are automatically detected from a seismic data set, a tabular data structure well suited for analytics is available. Time-lapse seismic data is a well-known tool in reservoir management. Integration of multiple surveys in the analysis can become cumbersome as the number of surveys grows. In the Seismic Tiles data structure, each reflector segment (i.e., tile, represented by a row) can store information from multiple surveys (each attribute represented as a column), aiding automatic interpretation. Tailored workflows exploring the data structure also exist. By associating each tile to a horizon, we work with amplitude objects having horizon attributes instead of horizon objects with amplitude attributes. This allows us to query the seismic data to find where specific transmissibility conditions between formations are indicated by the data. The Seismic Tiles technology is general and will aid interpretation wherever we can formulate specific criteria for what we would like to identify or do with the seismic data. The use cases shown are a subset of the potential implementation for time-lapse seismic, and time-lapse seismic is a subset of the domains of implementation.
