Laboratory Services Since 1989 LABORATORY NARRATIVE Modified ASTM D-1945 Kleinfelder Workorder#1002070F Twenty 6 Liter Stimma Special (SIlVI Certified) samples were received on February 02, 2010. The laboratory performed analysis via modified ASTM Method D-1945 for Helium in natural gas using GC/TCD. The method involves direct injection of 1.0 rnL of sample. Method modifications taken to run these samples are summarized in the table below. Specific project requirements may over-ride the ATL modifications. Requirement ASTMD-1945 ATL Modifications Normalization Sum of original values Sum of original values may range between 85-115%. should not differ from Normalization of data not performed. 100.0%by more than 1.0%. Sample analysis Equilibrate samples to No heating of samples is performed. 20-50°F.above source temperature at field sampling Sample calculation Response factor is Peak areas are used for all target analytes to quantitate calculated using peak concentrations. height for C5 and lighter compounds. Reference Standard Concentration should A minimum 3-point linear calibration is performed. The not be<half of nor acceptance criterion is%RSD</= 15%. All target analytes differ by more than 2 X must be within the linear range of calibration(with the the concentration of exception of 02,N2,and C6+Hydrocarbons). the sample.

The laboratory performed analysis via modified EPA Method TO-15 using GUMS in the SIM acquisition mode. This workorder was independently validated prior to submittal using'USEPA National Functional Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based, logic driven, independent validation engine was employed to assess completeness, evaluate pass/fail of relevant project quality control requirements and verification of all quantified amounts.

Laboratory Services Since 1989 LABORATORY NARRATIVE Modified ASTM D-1945 Kleinfelder Workorder#1003669B Two 6 Liter Summa. Special (SIM Certified) samples were received on March 30, 2010. The laboratory performed analysis via modified AST.M Method D-1945 for Helium in natural gas using GC/TCD. The method involves direct injection of 1.0 mL of sample. Method modifications taken to run these samples are summarized in the table below. Specific project requirements may over-ride the ATL modificaticm. Requirement ASTMD-1945 ATL Modifications Normaiization Sum of original values Sum of original values may range between 85-115%. should not differ from Normalization of data not performed. 100.0%by more than 1.0%. Sample analysis Equilibrate samples to No heating of samples is performed. 20-50'F.above source temperature at field sampling Sample calculation Response factor is Peak areas are used for all target analytes to quantitate calculated using peak concentrations. height for C5 and lighter compounds. Reference Standard Concentration should A minimum 3-point linear calibration is performed. The not be<half of nor acceptance criterion is%RSD</=15%. All target analytes differ by more than 2 X must be within the linear range of calibration(with the the concentration of exception of 02,N2,and C6+Hydrocarbons). the sample. Run 2 consecutive checks; must agree within 1%. Sample injection Volume 0.50 mL to achieve i 1.0 mL. Methane linearity. Receiving Notes There were no receiving discrepancies. Analytical Notes There were no analytical discrepancies. Definition of Data Oualifying Flags Six gjalifie s may-have been used on the data analysis sheets and indicate as follows: J- Estimated value.
