Abstract: A system for fracturing a hydrocarbon bearing formation includes a valve including a tubular housing having a bore therethrough and one or more flow ports formed through a wall thereof. One or more locator tags are embedded in the housing, and a sleeve is disposed in the housing and movable relative thereto between an open and a closed position. The system also includes a shifting tool comprising a shifter movable between an extended position and a retracted position and operable to engage the valve sleeve. The shifting tool includes a lock that keeps the shifter extended in the locked position and allows the shifter to retract in the unlocked position. The shifting tool also includes an antenna for detecting the locator tags, and an electronics package in communication with the antenna and the actuator for operating the actuator in response to detection of the locator tags.

Abstract translation: 用于压裂含烃地层的系统包括阀，其包括具有穿过其中的孔的管状壳体和通过其壁形成的一个或多个流动端口。 一个或多个定位器标签嵌入壳体中，并且套筒设置在壳体中并且可以在打开位置和闭合位置之间相对于其移动。 该系统还包括换档工具，其包括可在延伸位置和缩回位置之间移动并可操作以接合阀套的换档器。 换档工具包括锁定件，其将变速器延伸到锁定位置并允许变速器在解锁位置缩回。 换档工具还包括用于检测定位器标签的天线以及与天线和致动器通信的电子组件，用于响应于定位器标签的检测而操作致动器。
