The objective of this proposed research is to develop an improved understanding of mini-frac tests in tight formations through coupled reservoir and geomechanical modeling. The current research will focus on attaining a standard methodology for mini-frac interpretation that can be widely accepted by the industry. The objectives will be met through building a representative model for min-fracturing in tight formation, simulating the ideal leak-off behavior followed by non-ideal phenomena such as well bore storage, pressure dependent leak-off and height recession - transverse storage etc. While modeling min-fracturing - simulated pressure response will be analyzed using both Holistic and PTA based approach in an effort to identify appropriateness of any such method in explaining various phenomena noted in the literature.

这项研究的目的是通过油藏和地质力学耦合建模，提高对致密地层中微型压裂测试的理解。目前的研究将侧重于获得一种可被行业广泛接受的小型压裂解释标准方法。通过建立具有代表性的致密储层最小压裂模型，模拟理想漏失后的非理想现象，如井筒储集、压力相关漏失、高度衰退-横向储集等。在进行最小压裂模拟压力响应建模时，将使用整体方法和基于PTA的方法进行分析，以确定任何此类方法在解释文献中提到的各种现象时的适用性。
