摘要： 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.

摘要： A perforating gun technique. The technique includes perforating with the gun in a manner that deforms internal support structure thereof. Thus, follow-on treatment with a breakup fluid tailored to the material of the support structure may be utilized to dissolve the structure. The carrier of the gun which houses the structure may then be utilized as a conduit for fluid flow.

摘要： Managed pressure drilling and completion systems and methods, usable to urge a passageway through subterranean strata, place protective lining conduit strings between the subterranean strata and the wall of said passageway without removing the urging apparatus from said passageway, and target deeper subterranean strata formations than is normally the practice for placement of said protective lining conduit strings, by providing apparatuses for reducing the particle size of rock debris to generate lost circulation material to inhibit the initiation or propagation of subterranean strata fractures.
