1 Sample User Script: Step by Step Matching Stavanger, June 15, 2004 Houston, June 23, 2004

2 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

3 Company: Service Class: Tool Series: Service-Channel Xref: Company Channel: Generic Service/Tool Class: Generic Curve Class:

4 Step 2: Verify Logging Company Reference: Look forSchlumberger Offshore Services Find Schlumberger with organization code = 440 OK

5 Company: Schlumberger, 440

6 Step 3: Verify Service Reference: Look forOrganization is Schlumberger = 440 Service is Compensated Neutron Find Compensated Neutron Tool with Code ‘CNT’ OK

7 Company: Schlumberger, 440 Service Class: Compensated Neutron Tool; CNT

8 Step 4: Find Well Log Tool Series Reference: Look forOrganization is Schlumberger = 440 Service Class is Compensated Neutron Tool = ‘CNT’ Find CNTH as a close match among several choices. OK

9 Company: Schlumberger, 440 Service Class: Compensated Neutron Tool; CNT Tool Series: CNTH, …

10 Step 5: Verify Curves for Service Reference: Look forOrganization 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.

11 Company: Schlumberger, 440 Service Class: Compensated Neutron Tool; CNT Tool Series: CNTH, … Service-Channel XReference: CNTH, … Company Channel: NPOR, NUCA but not HSGR

12 Step 5: Find Service from a Curve Reference: Look forOrganization is Schlumberger = 440 Channel Type = channel Channel Id = HSGR Find ‘HNGS’ = Hostile Natural Gamma Ray Sonde. Now check the tool series for this service.

13 Company: Schlumberger, 440 Service Class: Hostile Natural Gamma Ray Sonde ; HNGS Tool Series: Service-Channel XReference: HSGR Company Channel: HSGR

14 Step 6: Find Well Log Tool Series Reference: Look forOrganization 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…

15 Company: Schlumberger, 440 Service Class: Hostile Natural Gamma Ray Sonde ; HNGS Tool Series: HNGS-AA and HNGS-BA Service-Channel Xref: HSGR Company Channel: HSGR

16 Step 7: Verify Curves for Service Reference: Look forOrganization 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.

17 Step 8: Find Generic Tool Classes Reference: (a) Look forOrganization is Schlumberger = 440 Service is Compensated Neutron Tool = ‘CNT’ (b) Look forOrganization 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.

18 Company: Schlumberger, 440 Service Class: CNT, HNGS Tool Series: Service-Channel Xref: Company Channel: Generic Service/Tool Class: NEU SGR
