摘要： A device and method for retrieving a tool string from downhole locations through the use of one or more engagement sensors. The one or more engagement sensors are activated by the tool string engaging an overshot device. The one or more engagement sensor may be mechanical, electric, or magnetic and may be located at various locations on the overshot device, the tool string, or both. Additionally, any number of engagement sensors may be used at the same time.

摘要： A cable includes a conductor. A plurality of inner armor wires is wrapped around the conductor. At least some of the plurality of inner armor wires have non-circular and non-rectangular cross-sectional shapes. A plurality of outer armor wires are wrapped around the inner armor wires. At least some of the plurality of outer armor wires have non-circular and non-rectangular cross-sectional shapes.

摘要： Downhole cables are described that are configured to protect internal structures that may be detrimentally impacted by exposure to the downhole environment, by protecting such structures by at least two protective layers. In some examples, the structures to be protected may be housed in a protective tube housed within the protective outer sheath. The described configuration enables the use of structures such as polymer fibers in the cables for strength and load-bearing capability by protecting the fibers, by multiple protective layers, from exposure to gases or fluids within a wellbore.
