Tight carbonate gas well deliverability evaluation and reasonable production proration analysis

Abstract It is very important to accurately predict the gas well productivity and reasonably allocate production at early development stage of reservoirs. However, both non-Darcy stress sensitivity effects have not been investigated in dual-porosity model tight carbonate This paper proposed a new binomial deliverability single-well proration numerical model, which consider sensitivity. The field tests data validated accuracy analytical helpful method when lacking test. A geological was built on results log, testing, analysis. Then, reasonable analysis conducted based history matched model. index curve production–prediction MX22 several simulation cases were adopted analyze proration. indicate that 1/6 may be suitable for high In addition, absolute open flow rate from higher than equation, also shows pressure transient sometimes has some deviation formation property prediction. suggested comprehensively utilizing evaluation.
