Step 1. Well Log Received LOG HEADER Logged By: Schlumberger Offshore Services Service: Compensated Neutron Instrumentation: CNT-H, HNGS-BA, … Curves: (ignoring channels with units that are count rates, count rate ratios, …) (noting those with engineering units, such as porosity, inches, API gamma ray, …) NUCA, NPOR, NPL, NPHI, ENPH HNPO, HTNP, TNPH, HSGR

Step 2: Verify Logging Company • Reference: http://w3.posc.org/pwls/industry_data/organization.txt • Look for Schlumberger Offshore Services • Find Schlumberger with organization code = 440 • OK
Step 3: Verify Service • Reference: http://w3.posc.org/pwls/well_log_service_class.php • Look for Organization is Schlumberger = 440 Service is Compensated Neutron • Find Compensated Neutron Tool with Code ‘CNT’ • OK
Company:Schlumberger, 440 Service Class:Compensated Neutron Tool; CNT
Step 4: Find Well Log Tool Series • Reference: http://w3.posc.org/pwls/well_log_tool_series.php • Look for Organization is Schlumberger = 440 Service Class is Compensated Neutron Tool = ‘CNT’ • Find CNTH as a close match among several choices. • OK
Company:Schlumberger, 440 Service Class:Compensated Neutron Tool; CNT Tool Series:CNTH, …
Step 5: Verify Curves for Service • Reference: http://w3.posc.org/pwls/service_channel_x.php • Look for Organization is Schlumberger = 440 Source Type = Tool Source Id is Compensated Neutron Tool = ‘CNT’ • Find Several Curve Entries, e.g. NPOR, NUCA but not HSGR • Mystery: curve HSGR not expected for this service class.
Company:Schlumberger, 440 Service Class:Compensated Neutron Tool; CNT Company Channel:NPOR, NUCA but not HSGR Tool Series:CNTH, … Service-Channel XReference:CNTH, …
Step 5: Find Service from a Curve • Reference: http://w3.posc.org/pwls/service_channel_x.php • Look for Organization is Schlumberger = 440 Channel Type = channel Channel Id = HSGR • Find ‘HNGS’ = Hostile Natural Gamma Ray Sonde. • Now check the tool series for this service.
Company:Schlumberger, 440 Service Class:Hostile Natural Gamma Ray Sonde; HNGS Company Channel:HSGR Tool Series: Service-Channel XReference:HSGR
Step 6: Find Well Log Tool Series • Reference: http://w3.posc.org/pwls/well_log_tool_series.php • Look for Organization is Schlumberger = 440 Service Class is Hostile Natural Gamma Ray Sonde = ‘HNGS’ • Find HNGS with variants HNGS-AA and HNGS-BA is a second tool series also described as Hostile Natural Gamma Ray Sonde. Does it generate the HSGR curve? • Go on…
Company:Schlumberger, 440 Service Class:Hostile Natural Gamma Ray Sonde; HNGS Company Channel:HSGR Tool Series:HNGS-AA and HNGS-BA Service-Channel Xref:HSGR
Step 7: Verify Curves for Service • Reference: http://w3.posc.org/pwls/service_channel_x.php • Look for Organization is Schlumberger = 440 Source Type = Tool Source Id is Compensated Neutron Tool = ‘HNGS’ • Find Yes, our HSGR curve is here! • OK. We have a log from a double tool string generating Compensated Neutron and Gamma Ray services.
Step 8: Find Generic Tool Classes • Reference: http://w3.posc.org/pwls/well_log_service_class.php • (a) Look for Organization is Schlumberger = 440 Service is Compensated Neutron Tool = ‘CNT’ • (b) Look for Organization is Schlumberger = 440 Service is Hostile Natural Gamma Ray Sonde = ‘HNGS’ • Find Generic Well Log Tool Classes are NEU and SGR • OK!! NPD file name is WL_NEU-SGR_%%.DLIS where %% is the operator’s run number.
