    • A method for determining integrity of annular seals in wellbores. In an embodiment, two wellbores are selected that extend through a common geological formation which is capable of sealing against casing sections located in the wellbores. A pressure test is typically carried out in a first of the wellbores to check that the formation provides an effective seal, and a logging tool is typically run to obtain well log data from which can be derived a characteristic response that is associated with the formation providing an effective annular seal around the casing section in the first wellbore. A logging tool may then be run in the second of the wellbores to obtain a second set of well log data, which are comparable with the characteristic response to determine whether the formation provides an effective annular seal in the second wellbore.
    • 一种确定井眼中环形密封完整性的方法。 在一个实施例中,选择两个延伸穿过能够密封位于井眼中的套管部分的公共地质构造的井筒。 通常在第一个井筒中进行压力测试,以检查地层是否提供了有效的密封,并且通常运行测井工具以获得测井数据,从中可以得出与地层相关的特征响应 围绕第一井眼中的套管部分的有效环形密封。 然后可以在第二个井筒中运行测井工具以获得与特征响应相当的第二组测井数据,以确定地层是否在第二井筒中提供有效的环形密封。

    • A method is disclosed that generates design profiles and a surface therefrom that promote water drainage from soil in an area of interest. Topographical data describing an initial surface of the area of interest are used to form initial profiles. The method generates the design profiles using the initial profiles and desired design parameters such as minimum slope, maximum slope, optimal slope, maximum depth, optimal depth, starting elevation, ending elevation, rules of curvature, and rules of earth balancing. The method generates design surface profiles so that the cut volumes and fill volumes of the soil are at or near balance as much as possible from the available soil in the area of interest.
    • 公开了一种从感兴趣区域的土壤产生排水的设计简档和表面的方法。 描述描述感兴趣区域的初始表面的地形数据用于形成初始轮廓。 该方法使用初始轮廓和期望的设计参数(如最小坡度,最大坡度,最优坡度,最大深度,最佳深度,起始仰角,结束高程,曲率规则和土方平衡规则)生成设计轮廓。 该方法产生设计表面轮廓,使得土壤的切割体积和填充体积尽可能距离感兴趣区域中的可用土壤处于或接近平衡。
