In-person: 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.

• The presentation will initially introduce the concept of IORSim (jointly developed by the Institute for Energy Technology, NORCE, and the University of Stavanger) and its main features: Reservoir Model integration, topological sorting to ensure numerical stability, computation efficiency, and user experience.
• The IORSim capabilities are then demonstrated by history matching the Snorre water diversion pilot and predicting the reservoir performance over conventional water flooding. Between 2013 and 2019, the thief zone plugging lowered the water production by 1.18 MSm³ while the water cut decreased by 2.9 %. Moreover, due to the 1.34 MSm³ injection water reduction, the injection pump CO₂ emissions decreased by 8,931 tons or 34 %.
