    • A method of approximating or determining at least one dimension or other characteristic of at least one underground geological feature in a zone of interest proximate to a well bore includes generating an electric field in the zone of interest. At least two sensing electrodes are provided in the well bore and configured to detect differences therebetween in electric potential caused by at least one target object in the zone of interest. Proppant containing signal generating devices (SGD) is delivered into the geological feature(s). The SGD generate a detectable signal in response to at least one downhole condition or property. At least one receiver receives the detectable signals and provides data relating thereto. At least one dimension or other characteristic of the geological feature is approximated or determined based at least partially upon data provided by the sensing electrodes and receiver(s).
    • 近似或确定靠近井眼的感兴趣区域中的至少一个地下地质特征的至少一个维度或其他特征的方法包括在感兴趣区域中产生电场。 至少两个感测电极设置在井眼中,并被配置为检测由感兴趣区域中的至少一个目标物体引起的电位之间的差异。 含有信号发生装置(SGD)的支撑剂被输送到地质特征中。 SGD响应于至少一个井下状况或属性产生可检测信号。 至少一个接收器接收可检测信号并提供与其相关的数据。 至少部分地基于由感测电极和接收器提供的数据近似或确定地质特征的至少一个维度或其它特征。
