Brief Description: the above two projects are all at the national level and consisted

by leading reservoir engineering researchers. Their main purpose is to overcome the

technical difficulty of predicting reservoir forming law and targets and improving

high water-cut oil field recovery. In these projects, GridWorld is responsible for geo-

modeling.

model and seamlessly merging.


Cooperator: BGP

Time: 2014

Project: Research and Develop the 3D Geo-modeling Function of GeoEast Based on

SDK Constructed by DepthInsight

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.
