Towards a Systematic and Sequential Search for Open Fractures in Seismic Data

We present the results of extensive preconditioning and attribute analyses towards a systematic and sequential search for open fractures from depth migrated seismic data volume from offshore Malaysia. To delineate and quantify open fracture networks from seismic data, the three core elements to this workflow are respectively 1)fault network delineation, 2)fracture density zones estimation, and 3)open fracture zones identification. These are then used to visualize the most potent regions in the area. Then through 3D volumetrics, we quantify the amount of open fractures per region and identify areas of interest. We blend the results of all these three attributes and perform extensive validation and correlation with existing wells (producing wells as well as non successful wells) and the results showed a very good match for all wells. The proposed workflow we present in this abstract, may define future areas of high fractures networks. Only the seismic data was used to perform this analysis, and the well data was solely used for correlation and validation purposes. The processing workflows in this abstract will open the gateways for future projects with similar challenges and provides a new dimension in interpretation in search for open fractures from seismic data.
