Geomechanical modeling of mini-frac tests in tight formations

这项拟议的研究的目的是通过油藏和地质力学耦合建模来更好地理解致密地层中的微裂缝测试。目前的研究将集中于获得一种能够被业界广泛接受的微型裂缝解释的标准方法。这些目标将通过建立致密地层中微型压裂的代表性模型来实现，模拟理想的滤失行为以及随之而来的非理想现象，如井筒储存、压力相关的滤失和高度后退-横向储存等。在模拟微型压裂时，将使用整体和基于PTA的方法来分析模拟的压力响应，以努力确定任何此类方法在解释文献中所提到的各种现象时的适用性。

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.
