摘要： The method and apparatus can create excavation cavities suitable for drilling multilateral wellbores through the excavation using a kick-off. One embodiment of the method comprises isolating a wellbore at a determined location, excavating a downhole cavity in a wellbore above the determined location, and removing the apparatus for isolating the wellbore and the apparatus for excavating the downhole cavity from the wellbore to provide full access to the wellbore and the excavation cavity.

摘要： A method and apparatus associated with various phases of a well completion. In one embodiment, a method is described that includes identifying failure modes for a well completion. At least one technical limit associated with each of the failure modes is obtained. Then, an objective function for the well completion is formulated. Then, the objective function is solved to create a well performance limit.

摘要： The present application describes a method and modeling system for managing and modeling well completions. The method includes constructing a wellbore model of a completion. Then, the wellbore model may be applied to generate one or more simulated production profiles, wherein the simulated production profiles include two or more of pressures associated to depth, temperatures associated to depth, flow rates associated to depth, fluid flow velocities associated to depth, and any combination thereof. The completion and one or more sensors may be disposed into a well. Sensory data may be acquired or obtained from the sensors associated with the completion. The sensory data is examined to determine if production conditions have changed. If the production conditions have changed, one or more measured production profiles are generated from the sensory data and are compared to the at least one simulated production profile to determine a modification to the completion. Then, the completion is modified based of the determination. However, if the production conditions have not changed, well operations continue.
摘要翻译：本申请描述了一种用于管理和建模完井的方法和建模系统。该方法包括构建完井的井眼模型。然后，可以应用井筒模型以产生一个或多个模拟生产曲线，其中模拟生产曲线包括与深度相关联的两个或更多个压力，与深度相关联的温度，与深度相关联的流速，与深度相关联的流体流速，及其任何组合。完成和一个或多个传感器可以被放置在井中。可以从与完成相关联的传感器获取或获得感觉数据。检查感官数据以确定生产条件是否改变。如果生产条件已经改变，则从感官数据产生一个或多个测量生产曲线，并与至少一个模拟生产轮廓进行比较，以确定完成的修改。然后，根据确定修改完成。但是，如果生产条件没有改变，运作情况继续下去。
