Enhanced calibration treatment analysis for optimizing fracture performance: validation and field exakples

摘要

Current pressurre evaluation techniques that assess fracture behavor from calibration treatments are limited to predicting reservoir parameters that govern fracture growth. In addition, significant variability during the evaluation process can result in subjectivity and hence reduce the effectiveness of such tests. The recently proposed "after-closure" analysis attempts to overcome these limitiations by assessing the reservoir-dominated pressure response, following mechanical closure of a hydraulic fracture.
