CO2 Sequestration

Carbon capture studies help improve understanding of seals.

In today's Carbon Capture world, assessing seal capability at proposed CO2 storage sites is a prime requirement for choosing suitable long-term storage locations.

 

Carbon capture studies help our understanding of seals.

 

Seals are probably the least understood part of the petroleum system. This holds true for CO2 sequestration. Cores and sophisticated logs are historically limited to reservoir sections in hydrocarbon appraisal wells. This is the state of play because the main economic driver for data acquisition is optimising hydrocarbon production. Very rarely is seal cored! Fine-grained rocks, which make up the seals, are much less commonly studied in outcrop in comparison to reservoir rocks. Only very recently, due to the advent of shale gas exploration, have researchers and field geologists seriously started to study fine-grained rocks; and contrary to received wisdom they are finding that they are far from the assumed uniform, non-heterogeneous units they were only recently thought to be.

 

Use of methods such as Mercury Injection Capillary Pressure to predict column height, correlation of regional, primary and secondary seals from existing wells to determine thickness and continuity of potential seals, relating seal thickness to fault throw, fault mapping in 3D, and risking potential target prospects for technical and economic viability is helping us describe the critical characteristics of seals and potential carbon storage locations.

Detailed seismic analysis, including inversion to lithology and mapping of faults from seismic data is visualising potentially week spots at possible Carbon Capture and Sequestration (CCS) sites.

 

We proudly include CarbonNet and the Department of Primary Industries, Government of Victoria, Australia, among our clients and are privileged to have one of the world authorities on fault seal among our consulting team of geologists and geophysicists.

 

If you have a demanding CO2 project and would like the best analytical geologists and geophysicists to advise on your project, we'd be happy to discuss your requirements.
