Abstract

An expanding auger axis with a hollow end adapted to receive an unmovable sensor tube in which gamma ray, gamma spectrograph, and/or neutron sensors may be placed, the auger adapted to rotate or circulate a discrete media about the sensors.

Claims

exact text as granted — not AI-modified
1 . An apparatus for logging the properties of a discrete media, comprising:
 a. a rotatable auger, having a generally central auger shaft, the auger shaft having at least a portion having a central void, the void adapted to receive a sensor; and   b. an auger housing for containing the auger and the discrete media, wherein the auger is adapted to rotate the discrete media about the sensor.   
   
   
       2 . The apparatus of  claim 1 , further comprising drive means for rotatably driving the rotatable auger. 
   
   
       3 . The apparatus of  claim 1 , wherein the sensor is rotationally fixed relative to the auger housing. 
   
   
       4 . The apparatus of  claim 1 , wherein there is relative rotational movement between the sensor and the auger shaft. 
   
   
       5 . The apparatus of  claim 4 , wherein the sensor is fixed and the shaft rotates. 
   
   
       6 . The apparatus of  claim 4 , wherein the shaft rotates in a first direction and the sensor rotates in a second direction, the second direction opposite the first direction. 
   
   
       7 . The apparatus of  claim 1 , the sensor comprising a gamma ray sensor. 
   
   
       8 . The apparatus of  claim 1 , the sensor comprising a gamma spectrograph sensor. 
   
   
       9 . The apparatus of  claim 1 , the sensor comprising a neutron capture sensor. 
   
   
       10 . The apparatus of  claim 1 , further comprising a lead shield about the auger housing. 
   
   
       11 . The apparatus of  claim 1 , wherein the auger is further adapted to move the discrete media axially along the generally central shaft. 
   
   
       12 . The apparatus of  claim 1 , wherein the discrete media is cuttings from a drilling operation. 
   
   
       13 . A method of logging a property of a discrete media, comprising:
 a. providing at least one sensor for determining the property of the discrete media; and   b. providing relative movement of the discrete media about the sensor.   
   
   
       14 . The method of  claim 13 , wherein the discrete media is cuttings from a drilling operation. 
   
   
       15 . The method of  claim 13 , wherein the sensor is fixed. 
   
   
       16 . The method of  claim 13 , wherein the discrete media is tumbled about the sensor. 
   
   
       17 . The method of  claim 13 , wherein the discrete media is rotated about the sensor. 
   
   
       18 . The method of  claim 13 , the sensor comprising a gamma ray sensor. 
   
   
       19 . The method of  claim 13 , the sensor comprising a gamma spectrograph sensor. 
   
   
       20 . The method of  claim 13 , the sensor comprising a neutron capture sensor.
