CCS world projects: In Salah

Project Overview

The In Salah Project is one of BP’s two major gas projects in Algeria and is the largest dry gas joint-venture project in the country. The venture involves the development of seven proven gas fields in the southern Sahara, 1,200km south of Algiers. On-stream since July 2004, the project produces around 9 billion cubic metres of gas a year. In Salah is also the world’s first full-scale carbon dioxide capture project at a gas field. Rather than venting CO2 , the project compresses it and injects it into a large underground aquifer lower than the gas reservoir at 1,800 metres depth. Around 1Mt of CO2will be injected into the reservoir each year, with a total of approximately 17Mt of CO2 to be re-injected during the whole life of the project, reducing CO2 emissions of the project by 60%. The main objectives of this project are to demonstrate to stakeholders that industrial-scale geological storage of CO2 is a viable greenhouse gas (GHG) mitigation option and to assure people that secure geological storage of CO2 can be cost-effectively verified and that long-term assurance can be provided by short-term monitoring. CO2 injection costs $6 US /Tonne CO2 .
