    • A technique is described for interpretation of IPTT tests. In one implementation, the technique may be configured or designed to standardize the complete interpretation procedure of IPTT in a heterogeneous reservoir, using if available, modern wireline logs (such as, for example, nuclear magnetic resonance and imaging), dynamic data from wireline formation testers and/or any other relevant information (such as, for example, geological description, core data and local knowledge) as constraints on the interpretation. Additionally, an iterative method may be used to define formation layering. An advanced regression technology may also be used to obtain optimized horizontal and vertical permeabilities of reservoir layers. Further a graphical user interface (GUI) based IPTT workflow technique of the present invention provides an integrated user-friendly interpretation platform for analyzing formation testing pressures and flow rate measurements in order to estimate the values and associated uncertainties of local characteristics of a hydrocarbon reservoir such as, for example, local permeability, local reservoir pressure, local compressibility, etc.
    • 描述了一种用于解释IPTT测试的技术。 在一个实现中,该技术可以被配置或设计为使用如果可用的现代有线日志(例如,核磁共振和成像),来自电缆形成的动态数据,在异质储层中对IPTT的完整解释过程进行标准化 测试者和/或任何其他相关信息(例如地质描述,核心数据和本地知识)作为解释的约束。 另外,可以使用迭代方法来定义地层分层。 也可以使用先进的回归技术来获得储层优化的水平和垂直渗透率。 此外,本发明的基于图形用户界面(GUI)的IPTT工作流技术提供了用于分析地层测试压力和流量测量的综合的用户友好的解释平台,以便估计烃储层的局部特征的值和相关不确定性,例如 例如,局部渗透率,局部储层压力,局部压缩性等

    • A method for determining rock and fluid properties of a fluid-containing subsurface geological formation is provided. First, a low resolution model of the geological formation is initially created from a lumped average parameter estimation derived from at least fluid pressure transient data obtained along a linear wellbore that traverses the formation. Next, the model parameters are updated using grid-based parameter estimation in which the low resolution pressure transient data are combined with data from at least one of seismic data, formation logs, and basic geological structural information surrounding the linear wellbore. Depending on the data available, this process may be carried out in a sequential manner by obtaining and combining additional dynamic data at selected areas. Through this process, multiple realizations of the properties of the geological formation (within the geological structural model) may be created based from the pressure-data conditioned geostatistics i.e. geostatistics that have been informed by data from both static and dynamic sources. Finally, the dynamic simulation of models should be compared to the results of the lumped average parameter estimation to provide a final calibration of the created models.
    • 提供了一种用于确定含流体的地下地质构造的岩石和流体特性的方法。 首先,地质构造的低分辨率模型最初是从至少从穿过地层的线性井眼获得的流体压力瞬态数据得到的集总平均参数估计来产生的。 接下来,使用基于网格的参数估计来更新模型参数,其中低分辨率压力瞬态数据与围绕线性井筒的地震数据,地层日志和基本地质结构信息中的至少一个的数据组合。 根据可获得的数据,可以通过在选定区域获得和组合附加动态数据来以顺序方式来执行该过程。 通过这个过程,可以从压力数据调节的地质统计学(即由静态和动态源的数据通知的地质统计学)创建地质构造的性质(在地质结构模型内)的多重实现。 最后,模型的动态仿真应与集总平均参数估计的结果进行比较,以提供所创建模型的最终校准。

    • A system and method determine formation permeability and/or at least one property indicative of formation permeability of a subsurface geological reservoir having radial-flow. Pressure data is obtained with an observation probe during a formation test, wherein the observation probe is located at a setting position within an open hole wellbore formed within the reservoir. The system and method measure radial-flow response of the reservoir at or adjacent to the setting position of the observation probe by analyzing the collected pressure data. The formation permeability and/or at least one property indicative of the permeability of the reservoir is determined based on the measured radial-flow response of the reservoir at or adjacent to the observation probe.
