Publication number: 20140083186Abstract: A gravimeter, a gravimeter system, and a method for measuring gravitational acceleration within a borehole are described herein. The gravimeter includes a proof mass that is constrained by springs and an optical interferometer for measuring displacement of the proof mass. The optical interferometer generates a light path from a light source to a reflective surface on the proof mass. Spatial displacement of the proof mass from a reference position to a position of gravitational equilibrium is determined by measuring a change in length of the light path. In turn, gravitational acceleration can be determined from the spatial displacement of the proof mass. A number of such gravimeters can be used in a gravimeter system to make measurements of gravitational acceleration in variety of different directions.Type: ApplicationFiled: August 13, 2013Publication date: March 27, 2014Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: BENJAMIN LEVITT, MARTIN E.

Patent number: 7501817Abstract: The present invention is directed to a nuclear magnetic resonance apparatus and method for generating an axisymmetric magnetic field having long, straight contour lines in the resonance region. A magnetically permeable member is used to shape the static magnetic field generated by an array of permanent magnets. The magnetically permeable member minimizes variations of the static magnetic field in the formation due to vertical motion of the apparatus while obtaining a nuclear magnetic resonance measurement. Further, the magnetically permeable member may minimize variations of the static magnetic field in the formation due to lateral motion of the apparatus while obtaining a nuclear magnetic resonance measurement.Type: GrantFiled: March 3, 1998Date of Patent: March 10, 2009Assignee: Schlumberger Technology CorporationInventors: Bruno Luong, Krishnamurthy Ganesan, Martin E.
