Method For Determining Resistivity Derived Porosity And Porosity Derived Resistivity

US Patent:
5992228, Nov 30, 1999
Filed:
Oct 9, 1997
Appl. No.:
8/947810
Inventors:
Lanny L. Dunham - Houston TX
International Classification:
E21B 4900
US Classification:
7315205
Abstract:
An improved model and method for analyzing oil and gas well logs is disclosed. This method allows a log analyst to make an accurate interpretation of a well log in oil and gas bearing shaly sand formations by providing a means to correct for missing or faulty data. The present invention provides an improved model and method for determining resistivity when porosity is known and for determining porosity when resistivity is known. This methodology allows the determination of water saturation in a shaly sandstone formation using either resistivity, bulk volume clay or porosity data as a single input. Resistivity data can be corrected using density porosity. The combination of both resistivity and density porosity data in any well will allow corrections to questionable open hole log data. Correction of resistivity data for conductive clays, thin bed effects and hole angle is allowed.
