In-person @ NOD: Snorre conformance control pilot – Modeling the impact on oil recovery and CO2 footprint using IORSim

In 2013, the Snorre field operators implemented a large-scale sodium silicate injection pilot to divert the reservoir water flow, improve volumetric sweep efficiency, and reduce CO₂ emissions per barrel of produced oil. The presented study utilizes IORSim, a geochemical simulation tool, to numerically history match and predict the Snorre water diversion field pilot impact on field performance, reservoir life span, and CO₂ footprint. While an industry-standard reservoir simulator was used to compute the velocity fields of the fluid phases (e.g., water, oil, and gas), IORSim calculated the sodium silicate transport, polymerization, and permeability reduction along the temperature front.
