Daniel Wong is a Reservoir Engineer with GaffneyCline. He holds a PhD from Heriot-Watt University where he has been working on advanced applications in reservoir simulation. At GaffneyCline he is part of the excellent technical team in charge of O&G reserves and resources assessment, due diligence, and data analytics. He has has been at the forefront of CO 2 sequestration modelling and SRMS assessment. Abstract:“Carbon Capture and Storage (CCS) is a lot harder than it seems. Storage capacity can be far lower than a back-of-the-envelope calculation would suggest and keeping Carbon Dioxide (CO2) in the desired phase requires careful engineering. As the adoption of carbon pricing mechanisms increase in Asia Pacific, more CCS projects are expected to be developed. In this presentation, we provide an introduction to reservoir engineering considerations required in geological CO2 storage. The presentation provides an overview of storage mechanisms in depleted hydrocarbon reservoirs and saline aquifers, primarily concerning capacity, injectivity and containment. Examples of storage projects are also presented. Finally, the CO2 Storage Resources Management System (SRMS) is introduced.”
