Patent number: 10825008Abstract: Methods and apparatus identify downhole equipment and correlate input data with the equipment to improve planning and/or inventory operations. For some embodiments, oilfield equipment or tubular goods such as drill pipe include a shaped recess along an outer circumference for receiving a tag cartridge by shrink fitting. Once tagged, detector system configurations at pipe yards may facilitate logging the presence and location of each drill pipe and correlating specific data, such as inspection data, to each drill pipe. Further, this correlation populates a database utilized to achieve other business functions such as forecasting number of additional drill pipe needed to purchase, invoicing customers according to actual tracked wear/use of the drill pipe being returned, and providing well or job specific drill string population using known history pipe joints.Type: GrantFiled: November 21, 2017Date of Patent: November 3, 2020Assignee: Weatherford Technology Holdings, Inc.Inventors: Paul Steven Griggs, Patrick M. Ljungdahl, Stephen Sarradet, Larry Williams, Matthew G. Miller, Simon John Harrall, Tuong Thanh Le

Patent number: 8997879Abstract: A well containment assembly comprising a first pressure-containing device and a diverter spool. The diverter spool comprises a body having a longitudinal central axis and at least partially defining a primary flowbore, an upper connection assembly coupled to the body, a lower connection assembly coupled to the body, and a plurality of side outlets. Each of the plurality of side outlets has a longitudinal central axis and at least partially defines a secondary flowbore. Each of the plurality secondary flowbores is in communication with the primary flowbore, and the angle between the longitudinal central axis of the body and the longitudinal central axis of the plurality of side outlets is less than 90° with respect to the primary flowbore. The first pressure-containing device is coupled to the diverter spool via the upper connection assembly.Type: GrantFiled: September 1, 2011Date of Patent: April 7, 2015Assignee: Halliburton Energy Services, Inc.Inventors: Douglas N. Derr, Patrick M. Ljungdahl
