Sample Sets: Method for Evaluating Hydrocarbon-Containing Subterranean Formations Penetrated by a Directional Well Bore.

Bill Chandler
Lateral Exploration Labs, Graham, Texas

A method of evaluating a hydrocarbon-containing subterranean formation to identify potentially productive zones within the formation. The method may be particularly useful for evaluating formations penetrated by a least one directionally drilled well bore. The method can include releasing,capturing,and measuring at least one property related to hydrocarbon materials entrapped in rock samples obtained from the formation, and the results of the analysis can be use to perform at least one well bore-related activity, such as drilling, geo-steering, stimulating and/or producing a new well bore.

Procedure:
   Drilling a well bore into a hydrocarbon containing formation at an angle of 50 degrees or higher angle.
   Obtain drill cuttings from well bore.
   Release entrapped hydrocarbons from rock samples.
   Capturing released hydrocarbon.
   Measuring at least one property of released hydrocarbon.
   Organizing results on a plot ( Chandler Perforation Plot / or CP/PLOT )
   Transmitting organized results to an end user.
