摘要

The combination of pressure-transient and production-log (PL) analyses has prove valuable in characterizing reservoir flow behavior in the giant Tengiz field. Among the important findings is the absence of clear dual-porosity flow. This observation contra- dicts an earlier interpretation that the reservoir contains a well- connected, natural fracture network. Fracturing and other secondary porosity mechanisms play a role in enhancing matrix permeability, but their impact is insufficient to cause dual-porosity flow behavior to develop.
