Reservoir Response to Variation in Injection and Production at Different Timescales

Introduction of renewable energy sources such as wind or photovoltaic to power upstream activities in oil and gas production can reduce emissions and play an important part in the transition required to address the GHG challenges. A main challenge with the mentioned renewables is the variability in power production due to weather variations. This can be compensated by supply of non-renewable (thermal) power with associated CO2 emissions, if a stable power demand is required. Alternatively, power consumption can be allowed to vary in line with available renewables by identifying the least critical loads in the petroleum production system in terms of affecting the overall production. In the presented work, effect on oil and gas production from varying energy consumption in the top side facilities is investigated at different timescales. Water injection pumps, export pumps and compressors, and the oil processing plant are subject to variable energy input and hence the injection and production profiles are varied, or at times fully shut down. Dynamic effect on production profiles and effect on total performance were investigated at field scale using an open available full field reservoir model.
