| Class Definition for Class 166 - WELLS (6036 words) |
| Class 166 however, takes some miscellaneous subcombinations which may be disclosed as used only in drilling operations but which are in fact of general utility in wells, particularly when there is no suitable subclass provided in Class 175 and a suitable subclass is provided in Class 166. |
| Processes of cementing, plugging or consolidating as defined in Class 166 subclass 21 are distinguished from drilling with fluid processes classifiable in Class 175 subclasses 65+ by the interruption of the actual earth cutting operation of the drilling process. |
| Class 166 takes devices for taking a sample of fluid from a potential producing horizon of a well, but such sampling combined with measuring or testing or bore hole study is in Class 73. |
