Laboratory Study on Hydrate Production Using a Slow, Multistage Depressurization Strategy

Figure 4

Comparison between the numerical results and experimental results for two-step multistage depressurization. (a) The gas production rate and cumulative gas production evolution behaviors with time. (b) The pressure evolutionary behaviors at different locations in the simulated formation. The dash lines represent experimental results, while the solid lines represent numerical results.
