    • A method for determining flow distribution in a formation having a wellbore formed therein includes the steps of positioning a sensor within the wellbore, wherein the sensor generates a feedback signal representing at least one of a temperature and a pressure measured by the sensor, injecting a fluid into the wellbore and into at least a portion of the formation adjacent the sensor, shutting-in the wellbore for a pre-determined shut-in period, generating a simulated model representing at least one of simulated temperature characteristics and simulated pressure characteristics of the formation during the shut-in period, generating a data model representing at least one of actual temperature characteristics and actual pressure characteristics of the formation during the shut-in period, wherein the data model is derived from the feedback signal, comparing the data model to the simulated model, and adjusting parameters of the simulated model to substantially match the data model.

    • A method of determining a concentration of a component in a flow from a single source or layer contributing to a total flow using the steps of measuring the total flow rate at various depths and sampling the total flow at a depth between two successive sources, measuring a total concentration of one or more flow components within the total flow, repeating the measuring of the total flow rate, the sampling and total concentration in further intervals separating other pairs of successive sources, and determining the concentration of at least one component by solving a system of mass balance equations representing the total flow of the flow components at each sampling depth.
    • 使用以下步骤确定来自有助于总流量的单个源或层的流中的组分的浓度的方法,所述步骤是测量各个深度处的总流量,并在两个连续的源之间的深度处采样总流量,测量 在总流量内的一个或多个流动组分的总浓度,重复测量总流速,采样和总浓度进一步分隔其他对连续的源,并通过求解系统来确定至少一个组分的浓度 的质量平衡方程代表每个采样深度处的流量分量的总流量。
