GLJ is a global leader in Carbon Capture Utilization and Storage (CCUS) evaluation, offering specialized services to meet your unique business goals. With over 50 years of experience in energy evaluations and 30 years of expertise in CCUS and CCS, our dedicated team provides customized solutions for your needs. Our comprehensive services include site screening, geological modeling, dynamic simulation, independent evaluations, economic modeling, monitoring, and storage capacity certification. GLJ’s extensive experience in CCS, Enhanced Oil Recovery (EOR), gas storage, and reservoir surveillance gives our clients confidence in their business plans.
There are two main streams of carbon capture, CCUS and CCS where the “U” stands for Utilization. The pure sequestration or CCS projects take the anthropogenic CO2 and permanently sequester it in deep saline reservoirs or depleted hydrocarbon reservoirs. For CCUS cases CO2 is captured and transported for injection into EOR schemes. For many years the CO2 injected was not anthropogenically sourced but as emissions reductions have become a top priority in recent years these schemes are now sourcing anthropogenic CO2.
GLJ has over 25 years of Canadian and international experience in the evaluation of Carbon Capture and Storage (CCS) projects and Enhanced Oil Recovery (EOR) schemes. EOR experience includes the application of waterflooding, gas and CO2 injection, cyclic steam stimulation (CSS), steam flooding, and steam assisted gravity drainage (SAGD), as well as polymer and Alkali-Surfactant Polymer (ASP) flooding.
Our more recent work with CCS has been extensive, as our global client base aims to further investigate and invest in it’s potential as a key component of their emissions reduction strategies. GLJ holds important relationships with organizations with different skillsets so that we may offer clients an integrated project team capable of evaluating all aspects of the CCS value chain.
The CCUS Process – 4 Major Steps
- Capture: The separation of CO2 from other gases produced at large industrial process facilities such as coal and natural-gas-fired power plants, steel mills, cement plants, and refineries.
- Transport: Once separated, the CO2 is compressed and transported via pipelines, trucks, ships or other methods to a suitable site for geological storage.
- Utilization: Captured CO2 is utilized in Enhanced Oil Recovery (EOR) schemes into carefully selected hydrocarbon reservoirs via an injection well. Oil production is enhanced by forcing the unrecovered petroleum within the pore space to production wells which increases the rate of recovery.
- Storage: CO2 is injected into deep underground rock formations, usually at depths of one kilometer or more.
