摘要： A method of running tubulars includes attaching a load collar to a first tubular; landing the load collar on a load support member; connecting a second tubular to the first tubular; removing the load collar from the first tubular; and lowering the first tubular and the second tubular. In one embodiment, at least one of the first tubular and the second tubular is a screen.

摘要： An apparatus and methods for tracking a plurality of marine riser assets is provided. Part of a riser lifecycle monitoring system, the apparatus can include an oil and gas riser spider to connect a plurality of riser pipe sections during assembly of a riser pipe string. The riser spider forms an annulus around a first section of the plurality of riser pipe sections and supports the first section of the plurality of riser pipe sections during connection to a second section. The apparatus can also include an antenna to read a plurality of radio frequency identification tags, e.g., directional 125 kHz RFID tags, attached to outsides of the plurality of riser pipe sections. The antenna can include an oblong loop attached to and substantially spanning about half of an internal surface of the riser spider so that the antenna follows the contour of the riser spider.

摘要： Methods for gripping an oilfield tubular include engaging a band with a ring member to form a load ring. The band has an arcuate component with a gap separating first and second ends, an interior surface, and an inclined exterior surface. The ring member has an interior surface with a groove therein. The inclined exterior surface of the band is associated with the groove of the interior surface to form the load ring. The load ring can be engaged with an oilfield tubular, and a force can be applied such that the groove of the ring member engages the inclined exterior surface of the band for securing the load ring to the oilfield tubular.
