Correlation between per-well average dynamic reserves and initial absolute open flow potential (AOFP) for large gas fields in China and its application

Correlation between per-well average dynamic reserves and initial absolute open flow potential (AOFP) for large gas fields in China and its application

Based on performance data of over 600 wells in 32 large gas fields of different types in China, the correlation is established between per-well average dynamic reserves (G¯) and average initial absolute open flow potential (q¯IAOF) of each field, and its connotation and applicability are further dis...
