Abstract
A practical workflow is also developed and presented to estimate reservoir and hydraulic fracture properties using 2-phase RTA for hydraulically fractured vertical wells. The presented workflow works in a reverse order by first analysing boundary-dominated flow regime and then proceeds to other existing flow regimes developed at earlier production history of the well. Although analysis of each flow regime provides a standalone method to calculate some of reservoir properties, the full development of all flow regimes allows crosschecking and brings more confidence into calculation. In this workflow, the reservoir properties derived from later flow regimes, feeds earlier flow regimes to extract other reservoir variables such as fracture half-length. A hydraulically fractured CSG well from the Ordos Basin, China, is analysed using AI and the proposed workflow to demonstrate the field application of this study.
