1 The Main Objective of WITSML The Right-Time Seamless flow of well data between service companies and operating companies to speed up and enhance decision making.

2 Energistics Membership members members members ~ 10 members provide WITSML aggregation server solutions.

3 Therefore. MOST companies interested in WITSML are Consumers of the data, with client application that want easy, efficient access to wellsite data. WITSML today provides efficient transfer of this information.

4 BUT There is a problem! It Does not provide for data organisation or data management. Consumers want a consistent view of the data, regardless of source.

5 Status of WITSML Transmit at local NOC Service Company A Service Company B Service Company C Service Company D Standard Uid Log Curve Info Uid Curve Description Number of Curves Log Per Curve Curve Naming No No Not Clear > 100 No Different No No Clear < 100 Yes Different Yes Yes Please find summary of differences between Some are log object Yes from service companies: < 100 No Different clear Yes Some are clear < 100 No Different Service Company A sends unnecessary curves, and redundant information. Service Company B sends a Log Object for each Curve ~34 for each Run Service Company C sends Logs per section, whereas D sends them from surface to TD No Service Company follows Operator requested Curve naming and UOM

service companies: < 100 No Different clear Yes Some are clear < 100 No Different Service Company A sends unnecessary curves, and redundant information.

6 The Main Objective of WITSML So No Seamless Flow? The Virtual WITSML Server

7 Applications need to Understand each Format

8 Structure Transparency with a Virtual Server

9 The Virtual WITSML Server Presents a single view of the data, in a consistent structure, regardless of source. Different Implementations of WITSML data organization are transparent to the Application Ability to easily switch Realtime Displays between multiple wells as it presents a similar view to the end user, regardless of source. Ability to reduce number of WITSML objects from all mnemonics to only the data needed for specific users. (removes unnecessary data from the client query ) Applications will only require one set of Queries for any Service Provider Data Set, regardless of source. Reduces cost, complexity and most of all, user workload when consuming WITSML data into end user applications.

similar view to the end user, regardless of source. Ability to reduce number of WITSML objects from all mnemonics to only the data needed for specific users.

10 The Virtual WITSML Log Objects The Virtual Server manages log data to provide a consistent view, regardless of source data organization. Merge Multiple Logs into One Log Handle Curve Splicing Generate Logs with Calculated Curves Change Mnemonics or Units of Measure Splice logs together Virtual logs are created on the fly based on the original data to serve user specific queries. The original data remains undisturbed by any of the processing that we do for generating the Virtual log objects Virtual logs can be used to aid automation, standardising or processing. 3 rd Party Application can receive the data in the format that it requires.

logs are created on the fly based on the original data to serve user specific queries.

11 Implementation Virtual logs are in use today in major gulf NOC Reduces cost of internal data management applications. Applications only have to handle ONE data organisation format. End users can concentrate on the data Not how it got there or from whom. Can provide customized views for applications which still require a specific format.

Applications only have to handle ONE data organisation format.
