T S Ramakrishnan, David J Wilkinson: Well logging method for determining fractional flow characteristics of earth formations. Schlumberger Technology Corporation, Leonard W Pojunas, Martin M Novack, March 5, 1996: US05497321 (34 worldwide citation)

A logging tool provides a log of fractional flow characteristics of formations surrounding an earth borehole. The logging tool is suspended in the borehole and resistivity measurements are made at different radial depths of investigation while the logging tool is moved through the borehole to obtain ...

Berwin W Darrow, David J Wilkinson: Lubrication control apparatus. International Business Machines Corporation, Kenneth P Johnson, April 27, 1982: US04326603 (25 worldwide citation)

Automatic lubrication control system in which current flow between two mating electrically conductive, lubricated members in sliding contact is integrated with respect to time and used to provide a control signal for a pump that applies lubricant to the contact surface. The voltage level resulting f ...

Terizhandur S Ramakrishnan, Lawrence M Schwartz, Edmund J Fordham, William E Kenyon, David J Wilkinson: Method for estimating pore structure in carbonates from NMR measurements. Schlumberger Technology Corporation, Mark Levy, William B Batzer, March 21, 2000: US06040696 (12 worldwide citation)

In this invention a new interpretation methodology has been developed. A pore structure model is used to compute the relaxation behavior. This model is then used as the kernel of a best-fit inversion scheme against the measured data, in contrast to inverting for a T.sub.2 distribution that relies on ...
