Identification of Casing Collars While Drilling and Post Drilling Using LWD and Wireline Measurements

摘要

Systems and methods identify and/or detect one or more features of a well casing by utilizing one or more downhole measurements obtainable by a downhole component. The one or more features of the well casing are identifiable and/or detectable from the one or more measurements associated with one or more properties of the one or more features of the well casing. The one or more measurements for indentifying and/or detecting a presence and/or a location of the one or more features of the well casing include sonic measurements, nuclear measurements, gamma ray measurements, photoelectric measurements, resistivity measurements and/or combinations thereof

1. A method for identifying a feature of a well casing located within a wellbore, the method comprising:
positioning a downhole component within the wellbore; obtaining one or more measurements associated with the feature of the well casing via the downhole component, wherein the one or more measurements is selected from the group consisting of sonic measurements, nuclear measurements, photoelectric measurements, resistivity measurements and combinations thereof; identifying a location of the feature of the well casing based on the one or more measurements; determining a measured depth based on the location of the feature; and performing a downhole action based on the measure depth.
