摘要： A method for measuring pressure exerted by earth material includes: providing a pipe with a longitudinal bore defining an inner diameter, providing a device with sensors to sense said inner diameter, wherein the device is to be moved within the pipe along the longitudinal bore, while a measurement of the inner diameter is taken in a first transversal direction at one longitudinal position of the pipe. Then a measurement of the inner diameter in a second transversal direction at the predetermined longitudinal position is taken, wherein the second transversal direction is oriented differently to the first transversal direction. Finally, an ovalization of the pipe is derived at that predetermined longitudinal position of the pipe through subtracting a diameter value of the first transversal direction from a diameter value of the second transversal direction.

摘要： Apparatus, systems, and methods may operate to detect rugosity in a borehole. Additional activity may include generating a rugosity correction, responsive to detecting rugosity in the borehole, by finding an effective borehole diameter, consistent with the presence of rugosity, for which a simulation of a model of the borehole using the effective borehole diameter generates simulation resistivity measurements that match, within a tolerance, resistivity measurements before execution of a borehole correction algorithm. Additional activity may include applying rugosity correction by generating resistivity logs, using the effective borehole diameter, that are corrected for rugosity and borehole effect. Additional apparatus, systems, and methods are disclosed.

摘要： A bottomhole assembly (BHA) coupled to a drill string includes one or more controllers, and a hole enlargement device that selectively enlarges the diameter of the wellbore formed by the drill bit. The hole enlargement device includes an actuation unit that may move extendable cutting elements of the hole enlargement device between a radially extended position and a radially retracted position. The actuation unit may be responsive to a signal that is transmitted from a downhole and/or a surface location. The hole enlargement device may also include one or more position sensors that transmit a position signal indicative of a radial position of the cutting elements. In an illustrative operating mode, one or more operating parameters of the hole enlargement device may be adjusted based on one or more measured parameters. This adjustment may be done in a closed-loop or automated fashion and/or by human personnel.

摘要： Methods for measuring wellbore gauge and dogleg severity are disclosed. The methods include deploying a downhole tool in a subterranean wellbore. The downhole tool includes first and second axially spaced stabilizers deployed on at least one tool body section coupled to a universal joint. The method for measuring wellbore gauge further includes measuring first and second axial directions of the tool body section when the universal joint is tilted in corresponding first and second cross-axial directions and processing the first and second measured axial directions to estimate the wellbore gauge. The method for measuring dogleg severity further includes measuring first and second tilt angles of the universal joint when the universal joint is tilted in corresponding first and second cross-axial directions and then processing the first and second measured tilt angles to estimate the dogleg severity.

摘要： A system, method and computer-readable medium for developing an earth formation is disclosed. A tool conveyed in a borehole induces a stress in the earth formation proximate a borehole. A sensor assembly obtains a measurement of a physical property of the borehole at a plurality of azimuthal locations in the borehole. The values of the physical property are indicative of the induced stress in the formation. A processor forms an image of the borehole using the obtained measurements of the physical property, estimates an azimuthal variation with borehole depth of the induced stress in the formation from the formed image, and alters an operational parameter of a device for developing the earth formation using the estimated azimuthal variation with depth of the induced stress in the formation.
