A landing nose adapted to deploy a sensor package within a tubular string may include one or more fins. The fins may be positioned to extend radially outwardly from the body of the landing nose and extend beyond the end of the landing nose body. The landing nose may be adapted to seat against a landing ring positioned within the tubular string. The fins may be adapted to, when the landing nose is seated, allow fluid to flow between the fins and through a central aperture of the landing ring. The fins may also be adapted to reduce the opportunity for the landing nose and sensor package to catch on any protrusions or features of the tubular string. In operation, the landing nose and sensor package may be run through the tubular string from the surface until the landing nose contacts the landing ring. The sensor package may then survey the wellbore as the tubular string is tripped-out from the wellbore.

Method and apparatus for through-tubular sensor deployment

A sonde based antenna is used for communication within a wellbore. The sonde based antenna may include a toroidal antenna positioned about a conducting element. The sonde may be positionable within a gap sub. The sonde may be electrically connected to the first and second tubulars of the gap sub such that the tubulars are electrically coupled by the conducting element and are otherwise electrically insulated. The sonde may include a first and second structural member, the first and second structural members being electrically insulated except by the conducting element. The first and/or second structural element may extend through and/or around the toroidal antenna to, for example, add structural rigidity to the sonde.
