  • Patent number: 11542791
    Abstract: Systems and methods for casing drilling riserless sections of a subsea bore may include casing drilling a section of a bore for a casing of the subsea bore to a predetermined depth. The method also may include, while casing drilling the section of the bore, obtaining information indicative of pore pressure and fracture pressure of a geological formation through which the section is casing drilled, and determining a pressure range based at least in part on the pore pressure, the fracture pressure, and a modification to mechanical properties of the geological formation due to the casing drilling of the section. The method further may include selecting, based at least in part on the pressure range and the predetermined depth, a pressure of the bore for casing drilling the section.

  • Patent number: 7603296
    Abstract: Items of equipment and assemblies for use in drilling or completion of a well or in other well operations are monitored from the time they are assembled for shipment to a particular well site for a job through the time of delivery and installation at the well site. Radio frequency identifier devices (RFID's) are mounted with the items to electronically tag them as they are assembled for shipment. The items are assembled into containers which can be readily inventoried during transit to detect loss or pilferage. Detailed information about the individual items can be encoded into the RFID at the time of electronic tagging. If desired, the shipping containers can be provided with separate RFID's detailing the particular items within the container and the progress of the shipment monitored remotely by satellite or the like.
