Topics to be covered are CCS well design, including how to plan for and mitigate low pH reservoir influences (external issues), borehole conditions (internal issues), and wellhead and Christmas Tree (surface issues). We will build off earlier discussions in Session 1 and begin to incorporate tangible design criteria that pertain to specific operational PVT conditions. For example, what are the operating ranges of pressures, volumes (rates), or temperatures expected, and how should those guide the design? How “pure” or “water-free” is the CO2 to be injected, and how do various contaminants, such as free oxygen in the injectate and the Cl⁻ content in the reservoir fluid, affect the choice of construction materials?  Finally, we'll address practical considerations for material selection, given concerns around availability, lead times, and cost, which may impact project viability.
