Patent number: 7500388Abstract: A wireline-conveyed side-wall core coring tool for acquiring side-wall core from a geological formation for performing in-situ side-wall core analysis. The coring tool has a core analysis unit operable to measure geophysical properties of an acquired side-wall core. The measured geophysical properties may be used to determine the success of the acquisition of side-wall cores by the coring tool. The core analysis unit is operable of performing an in-situ interpretation of measured geophysical property of the side-wall core and transmitting in near real-time the measurements or the interpretation results to surface data acquisition and processing apparatus.Type: GrantFiled: December 15, 2005Date of Patent: March 10, 2009Assignee: Schlumberger Technology CorporationInventors: Go Fujisawa, Oliver C.

Patent number: RE39803Abstract: A non-vibrating capacitance probe for use as a non-contact sensor for tribological wear on a component. The device detects surface charge through temporal variation in the work function of a material. A reference electrode senses changing contact potential difference over the component surface, owing to compositional variation on the surface. Temporal variation in the contact potential difference induces a current through an electrical connection. This current is amplified and converted to a voltage signal by an electronic circuit with an operational amplifier.Type: GrantFiled: May 1, 2001Date of Patent: September 4, 2007Assignee: Georgia Tech Research CorporationInventors: Steven Danyluk, Anatoly Zharin, Elmer Zanoria, Lennox Reid, Kenneth Hamall
