Abstract
Summary
We present a case study of the early stages of the storage development of an onshore Bioenergy with Carbon Capture and Storage project in Saskatchewan, Canada. The focus is on how 2D seismic is used to help determine the project’s suitability, siting, risk management, and Initial Characterization. We highlight the intersection of site specificity, economics and data availability. The project is locally unique due to its modest scale, proximity to sedimentary provenance in the storage complex— the Deadwood formation—its shallow depth and paucity of both wells and modern log data, including a complete lack of sonic logs. These site-specific issues increased the need for seismic imaging, while at the same time creating challenges for an accurate seismic interpretation. The lack of sonic logs was an exigent problem, necessitating the creation of an ad-hoc method for creating pseudosonic and pseudo-synthetic seismic and seismic models. The method was more successful than expected and resulted in synthetic models of sufficient quality to inform the location and magnitude of erosion of the DDWD seal section on the 2D seismic. In turn, this led to the critical decision to relocate the site and optimized subsequent efforts in the Initial Characterization stage.
