摘要： A method is provided for determining formation resistivity, anisotropy and dip from wellbore measurements includes moving a well logging instrument through subsurface formations. The instrument includes longitudinal magnetic dipoles and at least one of tilted and transverse magnetic dipoles. Formation layer boundaries and horizontal resistivities of the formation layers are determined from longitudinal magnetic dipole measurements. Vertical resistivities of the formation layers are determined by inversion of anisotropy sensitive measurements. Improved vertical resistivities of the formation layers and dips are determined by inverting symmetrized and anti-symmetrized measurements. Improved vertical resistivities, improved boundaries and improved dips are determined by inversion of the all dipole measurements. Improved horizontal resistivities, further improved layer boundaries and further improved dips are determined by inversion of all dipole measurements.

摘要： An orientation vector, referred to hereinafter as the “geosteering vector,” is directed to the more conductive formation area within the DOI of the tool and away from the more resistive formation areas. Accordingly, drilling in a direction opposite the geosteering vector leads to more resistive formation. Also, the disclosed geosteering vectors obtained from the real and imaginary components will not align with each other for non-planar formations and therefore the misalignment of the geosteering obtained from real and imaginary components is indicative of a non-planar formation. A superposition method is disclosed which can be used to calculate electromagnetic (EM) couplings in a non-planar geometry formation (as well as in a planar geometry formation) in real time, without requiring two or three dimensional modeling calculations.

摘要： A system and a method use dual telemetry for tools located in a wellbore. A first telemetry system and a second telemetry system coordinate communication with the tools. Both the first telemetry system and the second telemetry system may transmit data regarding the tools and/or drilling conditions from the tools to a surface location simultaneously. The first telemetry system or the second telemetry system may communicate with the surface location if communication using the other telemetry system is interrupted. The first telemetry system and the second telemetry system may have a master/slave relationship so that data requests from a specific telemetry system do not interfere with data requests from the other telemetry system.

摘要： Exemplary embodiments provide semiconductor devices with a high-quality semiconductor material on a lattice mismatched substrate and methods for their manufacturing using low temperature growth techniques followed by an insulator-capped annealing process. The semiconductor material can have high-quality with a sufficiently low threading dislocation (TD) density, and can be effectively used for integrated circuit applications such as an integration of optically-active materials (e.g., Group III-V materials) with silicon circuitry. In an exemplary embodiment, the high-quality semiconductor material can include one or more ultra-thin high-quality semiconductor epitaxial layers/films/materials having a desired thickness on the lattice mismatched substrate. Each ultra-thin high-quality semiconductor epitaxial layer can be formed by capping a low-temperature grown initial ultra-thin semiconductor material, annealing the capped initial ultra-thin semiconductor material, and removing the capping layer.
