  • Patent number: 12163417
    Abstract: An integrated drilling system includes a rotary steerable control unit and an electromagnetic LWD control unit deployed in an external collar. The rotary steerable control unit is deployed below the electromagnetic LWD control unit and is configured to control a direction of drilling of the integrated drilling system. A near bit electromagnetic antenna is deployed in a recess on the collar circumferentially about the rotary steerable control unit. At least one electromagnetic transmitter and at least one electromagnetic receiver are deployed in corresponding recesses in the collar circumferentially about the electromagnetic LWD control unit with the at least one transmitter and at least one receiver configured to make electromagnetic logging measurements while drilling. An electrical jumper provides an electrical connection between the near bit electromagnetic antenna and the electromagnetic LWD control unit.

  • Patent number: 8498852
    Abstract: Methods and systems for characterizing hydraulic fracturing of a subterranean formation based upon inputs from sensors measuring field data in conjunction with a fracture model. Such characterization can be generated in real-time to automatically manipulate surface and/or down-hole physical components supplying hydraulic fluids to the subterranean formation to adjust the hydraulic fracturing process as desired. The hydraulic fracture model as described herein can also be used as part of forward calculations to help in the design and planning stage of a hydraulic fracturing treatment. In a preferred embodiment, the fracture model constrains geometric and geomechanical properties of the hydraulic fractures of the subterranean formation using the field data in a manner that significantly reduce the complexity of the fracture model and thus significantly reduces the processing resources and time required to provide accurate characterization of the hydraulic fractures of the subterranean formation.
