  • Method For Improving Resolution Of Nuclear Magnetic Resonance Measurements By Combining Low Resolution High Accuracy Measurements With High Resolution Low Accuracy Measurements

    view source
  • US Patent:
    6600315, Jul 29, 2003
  • Filed:
    Dec 14, 2000
  • Appl. No.:
    09/681061
  • Inventors:
    Nicholas J. Heaton - Houston TX
    Charles Flaum - Ridgefield CT
    Chanh Cao Minh - Katy TX
  • Assignee:
    Schlumberger Technology Corporation - Sugar Land TX
  • International Classification:
    C01V 300
  • US Classification:
    324303
  • Abstract:
    A method that is usable with an NMR measurement apparatus includes averaging first spin echo trains acquired from different regions of a sample to form a second spin echo train. The first spin echo trains are used to produce a first estimate of a property of the sample, and the first estimate has a first resolution and a first accuracy. The second spin echo train is used to produce a second estimate of the property, and the second estimate has a second resolution that is lower than the first resolution and a second accuracy that is higher than the first accuracy. The first and second estimates are combined to produce a third estimate of the property. The third estimate has a third resolution near the first resolution of the first estimate and a third accuracy near the second accuracy of the second estimate.

  • International Classification:
    G01V 5/12
  • US Classification:
    250256, 2502693, 250265, 250261

  • US Patent:
    6232778, May 15, 2001
  • Filed:
    Jun 11, 1998
  • Appl. No.:
    9/096320

  • Assignee:
    Schlumberger Technology Corporation
  • International Classification:
    G01V 300
  • US Classification:
    324303
  • Abstract:
    The present invention provides methods for determining the bound fluid volume (BFV) of a formation utilizing nuclear magnetic resonance (NMR) techniques in which less than full polarization occurs and in which less than a complete NMR distribution is acquired. The effect of the polarizing static magnetic field is shortened in time by applying a shortened wait time between NMR measurements so that only the bound fluid of the formation is polarized. The shortened wait time is effectuated by early application of the oscillating magnetic field to the formation which, in conjunction with a limited number of refocusing pulses, induces signals in the formation that are measured by the NMR tool. The peak amplitude of these signals corresponds to the BFV. The present invention provides information so that a partial polarization calculation curve in T. sub.

  • Filed:
    Sep 7, 1989
  • Appl. No.:
    7/405396
  • Inventors:
    Charles Flaum - Houston TX
    James E. Galford - Sugarland TX

  • Assignee:
    Schlumberger Technology Corporation - Houston TX
  • International Classification:
    E21B 4700
  • US Classification:
    73152
  • Abstract:
    A method for determining a characteristic of a subsurface geological formation enhances the vertical resolution of dual-detector measurements by utilizing a continuous calibration factor which is obtained from an environmentally compensated characteristic derived from at least two resolution-matched sensor signals, and from a resolution-matched sensor signal from the near-detector of the tool. This method also can enhance the statistical precision of the characteristic without degrading the vertical resolution.

  • Assignee:
    Schlumberger Technology Corporation - New York NY
  • International Classification:
    G01V 510
  • US Classification:
    250266
  • Abstract:
    A method for determining the porosity of a subsurface geological formation traversed by a borehole is provided. The method generally comprises obtaining a means which relates ranges of apparent formation porosity (. phi. sub. a) as determined by a neutron-neutron log, formation fluid salinities, formation total capture cross sections (. SIGMA. ), formation matrix and fluid constituents, and true formation porosity (. phi. sub. T) according to a predetermined equation. The predetermined equation relates the apparent porosity to a function of a modified migration length which is obtained in a semi-empirical manner (i. e. physics modifed by data). The modified migration length includes a slowing down length and a diffusion length, but causes at least the diffusion length to be a function of the slowing down length. The means which relates the apparent porosity to salinity,. SIGMA. , matrix and fluid constituents, and. phi. sub.

  • International Classification:
    G01V 300
  • US Classification:
    324303
  • Abstract:
    A method and apparatus for determining gas corrected porosity using nuclear magnetic resonance (NMR) and density measurements is disclosed. The total porosity (TCMR) or an earth formation is determined using an NMR tool. A log output is generated that indicates the density of the formation. The density porosity of the formation is determined from the log output. The difference between the TCMR-density porosity log accurately indicates the presence of gas. A gas corrected porosity,. phi. , and gas saturation, S. sub. g, are determined based upon the density porosity and TCMR.
