3. PetroSteer / GeoSteer Consulting Services
 Well Trajectory Design Base on 3D Geomodels
 Real-Time Wellbore Optimal Placement
 Best Solution to Uncertainty and Sweet-Spots Detection

4. Oil Sands ( SAGD/Mining) and Heavy Oil Projects
 Special ways developed to build the 3D models and to evaluate and
develop oil sand (SAGD/Mining) and heavy oil reservoir.
 The 3D models built in three cases (upside, base and lowside cases)
based on the stochastic simulation result using different channel
ranges.
 The reserve estimation, net pay map, reservoir quality map and
simulation model were made from the 3D geological model.

5. Conventional Oil & Gas Projects
 Standard Industry Flow to Develop 3D Geomodels
 Geomodels Used for Evaluation and Development
