Application of Well Test Data to Evaluation of Hydraulic Fracturing Performance

Abstract

Abstract: Buildup test is now recognized to be the most effective method for evaluation of hydraulic fracturing performance. Formation pressure and effetive permeability can be estimated by pre fracturing buildup test data, then applied to make a proper interpretation for hydraalic frac-tures together with the post-fracturing buildup test data in order to avoid that different results of interpretation take place and provide correct e-valuation of the frac-performance. In this paper, 20 fractured wells in Zhundong low-permeability reservoir and their hydraulic fracture featnres have been explained by the buildup test method, with which comparison of calculated results from a 3D hydraulic fracturing model is conducted, followed by overall evaluation of frac-performance in Zhundong oilfield by nsing these buildup test data.

Key words: buildup analysis, hydraulic fracturing, fracture conductivity, performance, evalnation
