Optimization of CO2 EOR and geological sequestration in high-water cut oil reservoirs

Journal of Petroleum Exploration and Production Technology
In terms of the collaborative optimization of CO2 flooding for Enhanced Oil Recovery (EOR) and CO2 sequestration, previous studies have co-optimized both cumulative oil production and CO2 sequestration by various algorithms. However, these solutions fail

Estimation of time of peak gas production in coalbed methane wells using production data analysis

, 2015
For coalbed methane (CBM) wells with rising gas production, time to reach peak of gas production and peak gas rate are two fundamental features of a production profile. This paper investigates the time of occurrence of peak of gas production in CBM wells
