2. History • In 2002 Smith developed two “helper” utilities to graphically map information between a database and a WITSML document • XtrudeTM - XML export tool • XhumeTM - XML import tool • Using these tools a developer can add XML capability to an existing program with as little as 3 lines of code, without extensive XML or WITSML knowledge

3. Objective • The two tools were limited to generating XML files which would be then consumed by application • There was a need for a tool to query the data in different WITSML stores, apply transformations to the data and view the results before it is actually stored

4. Features • Verification of Use Case Scenarios and Work Process Functions • Maintenance tool • Performance monitoring of different WITSML servers using multiple queries to benchmark • Provides persisted connections • Supports both v 1.2 and v 1.3.1 WITSML Server queries • Fully configurable

5. WITSML Stores Tested Compatibility • Sense Intellifield (Version 1.2.0 and 1.3.1) • Pason (Version 1.2.0) • Petrolink (Version 1.2.0) • Visean (Version 1.1.0) • Baker Hughes (Version 1.2.0) • Halliburton (Version 1.2.0) • Schlumberger (Version 1.2.0) • Aspen Tech (Version 1.2.0) • Datalog (Version 1.2.0)

6. Product Features Connection Manager

7. Product Features Expanded Tree View

8. Product Features Tabbed View of multiple WITSML Stores

9. Product Features XML view of a Standard Query

10. Product Features Grid View of a Standard Query

11. Advanced Features Database Mapping

12. Advanced Features Query Configuration

13. Advanced Features Stored Procedures and User Defined Functions Example Consider the following translation expression:  @Func1(%value%) %else% @Func2(%value%) %else% @Func3() if %value% is not available, the expression value will be the return value of Func3, as the first two functions cannot be called. If %value% has a value, but for some reason Func1 has an unhandled exception, then Func2's value will be used. If the stored procedure Func1 always catches and handles all errors, then Func2 can never be called.//-------------------------------------------------------------------------------------------------------------//These are test functions to test the user defined function calls. These call functions//in the UserFunctions.dll installed with this product. function integer test1(integer a,integer b){   return @AddInts(a,b)*3;}function number test2(number a,number b){   return @AddNumbers(a,b);}
