Abstract: A method and apparatus are provided for making directional measurements toward a formation of different resistivity that is proximate to the borehole, but which is not penetrated by the borehole. The disclosed methods and apparatus include the use of at least one insulated gap and at least one magnetometer positioned within a non-magnetic housing that is disposed within a non-magnetic tubular. An electric current is applied across the insulated gap, which results in current leaking into the surrounding formations. When a formation of contrasting resistivity is proximate to the logging apparatus, the magnetometer detects a secondary magnetic due to the contrasting formation. The direction of the secondary magnetic field can be used to determine the direction to the contrasting formation. The magnitude of the secondary magnetic field can be used to determine the distance position to the contrasting formation.

Abstract: In one example, a data center may be built in modular components that may be pre-manufactured and separately deployable. Each modular component may provide functionality such as server capacity, cooling capacity, fire protection, resistance to electrical failure. Some components may be added to the data center by connecting them to the center's utility spine, and others may be added by connecting them to other components. The spine itself may be a modular component, so that spine capacity can be expanded or contracted by adding or removing spine modules. The various components may implement functions that are part of standards for various levels of reliability for data centers. Thus, the reliability level that a data center meets may be increased or decreased to fit the circumstances by adding or removing components.
