Today’s energy industry isn’t the one your parents knew. Not very long ago, players in the energy industry were grouped, at least in peoples’ minds, by their business lines. Some were oil companies, some were gas, some explorers, others, producers. Pipeline companies moved the products that others produced. Coal-fueled electricity generation, and everyone generally knew what the others were up to. The world has changed and so has the energy sector and all its players.

The world’s energy needs continue to increase but socio-economic, environmental priorities and political imperatives have increasingly been converging and sometimes clashing so that global energy players are no longer segmented; their assets, their operations, their businesses, cross sector lines. Oil and gas companies are invested in and operate renewables, drillers are accessing mineral brines as part of the battery supply chain and new markets are being explored and developed.

This push to diversify assets, operations and business lines is new to many. It adds complexity and uncertainty to companies who might be exploring opportunities, contemplating projects or holding assets that are significantly different from what they have previously. GLJ are the industry experts in the full range of evaluations in the energy sector and its dedicated Integrated Studies team are global leaders in responding to our clients’ needs and bring together comprehensive data, insight and analysis to deliver robust solutions to complex challenges.

“Integration is a key to success for our industry, our customers, and their business. GLJ’s Integrated Studies are tailored to our clients’ needs and bring together comprehensive data, insight and analysis to deliver robust solutions to complex challenges.” says Greg Owen, GLJ’s Vice President of New Ventures and Technical Services. “GLJ’s Integrated Studies team has conducted over 40 in-depth integrated studies in dozens of countries on 6 continents. Our work in this area provides clients with the data, analysis, and recommendations they need to fully understand and take advantage of their whole asset-base.”

It is all about minimizing risk and maximizing value. That is the service our Integrated Studies team at GLJ provides our clients.”

In March, GLJ Integrated Studies team members will present at two conferences that consider issues that are relatively new in the energy sector, including CCS/CCUS.  GLJ’s Manager of Integrated Studies, Vicky Wang, presents GLJ’s study “Understanding Thermal-Induced Risks on CO2 Storage Capacity and Caprock Integrity: Integrating Real World CCS Data and Geomechanical Modeling of a Saline Aquifer in Central Alberta,” at the SPE, AAPG, SEG CCUS Conference in Houston.

GLJ’s team, including Vicky Wang, Zan Chen, Mitchell Gillrie, and Suzy Chen, quantified the risks of thermal effects on storage capacity and containment using real-world data from a CCS project. Vicky will explain how the injected cold CO2 encounters significant temperature changes from the wellhead to the bottomhole and storage destination in a deep saline aquifer. Understanding the thermal-induced risks, stemming from geomechanical uncertainties, micro-seismicity, and fluid property variations, is critical for successful Carbon Capture and Storage operations. GLJ’s study provides guidelines to mitigate the risks of containment breaches and assists with MMV plan updates. To learn more visit [CCUS 2024 Houston (ccusevent.org)]

At the SPE CET Conference in Calgary, Vicky presents GLJ’s report: Risk Mitigation and Pressure Management in the Strategic Planning of Regional CCS Hub System in Alberta.  Co-authored by Vicky Wang, Jordan Hughes, Mitchell Gillrie, Zan Chen, Graham Dolce and Suzy Chen, the report considers that five of the 25 hubs with approved evaluation permits are located adjacently to facilitate emission reduction from Alberta’s industrial heartland. Including the Quest CCS project, six hubs covering approximate 40,000 km2 aim to store CO2 in a large saline aquifer. However, there is limited information available regarding quantifying interference risks at a regional level. This study identifies critical risks and proposes mitigation plans to strategically manage the CCS projects from a large-scale aquifer perspective. It also indicates the necessities to establish regional protocols as guidance to proactively avoid potential significant interferences.

If you’re looking to get the most from your asset base and gain a deep understanding of the challenges you’re facing as well your full CCUS potential, get in touch with GLJ’s Integrated Studies Team.
