Brief Description: BGP has inserted our SDK into its self-developed software
GeoEast, which enables it possess capability of 3D Geo-modeling and could meet
the modeling requirement for forward modeling, inversion and reservoir
characterization. This project has entered into the final phase of testing and a new
version will be released soon. BGP will pay GridWorld for every user of GeoEast
and it will make GridWorld have stable income. In addition, the same cooperation
model has been discussed with other large oil service companies and software
companies.
