Single Well Solutions: logInversion*

   Uses well dataset from GeoInversion system

   Playback well logs using default and user-defined templates, and list and crossplot the dataset

    Define processing sections, where log response equations will be different

    Define processing zones within processing section, where parameters will be different

    Sections and zones can be guided from well markers. Graphic canvas is provided for interactively updating of sections and zones. A different color will highlight the sections and zones

   Two general components, rock or mineral, to define log response equations

   Support to select available log response equations

   Support to select rock components, such as clay, water saturation, sand and limestone if the rock component is selected.

   Support to select mineral components, such as illite, kaolinite, quartz, calcite, oil and water if the mineral component selected

   All parameters can be updated from Human Interface. Some parameters are global and most of parameters are section-variable and zone-variable. The parameters should be section-by-section and zone-by-zone checked and updated.

 

   A state-of-the-art technology, multi-objective optimization method, will be used for inversion. Whether sandstone formation or carbonates, this technique can achieve outstanding results.

Single Well Solutions: logInversion*

   All parameters are classified according to log response equations

    Log response equations consider the contributions of both flushed zone and undisturbed zone if needed.

   Seven resistivity equations (Archie, Dual-Water, Waxman-Smith, Indonesia, Nigeria, Simandoux and Venezuela) are available to calculate flushed and undisturbed zone saturation

   Predefined rules to self-adaptively add/delete the special components, such as coal to add when density is less than 1.5, etc

   Quality control conditions to solve the ill-posed problems, such as porosity > 0 and porosity <= maximum porosity from core analysis, are applied during inversion

   Interactive and batch inversion. The interactive inversion will be real-time to trace and to display the results. It is our special contributions to well logging inversion.
