Development of a decision-making system for coalbed methane development based on GIS

In order to reduce the risk of CBM exploration and development and save development cost, a decision-making system for coalbed methane development based on GIS is developed by using C# development tools. According to the principle of single factor index, fuzzy comprehensive evaluation, step optimization and BP neural network, the resource evaluation system is established; the well-type selection and well-pattern optimization system is built by using multi-fuzzy mathematical evaluation combined with Comet simulation software; based on the development method about GIS, combined with the public interface for external modules, the decision-making expert system with GIS for Coalbed methane is developed. It is a using exploration to traditional geology disciplines combined with expert system technology and GIS technology, the system can accurately decision-making for Coalbed Methane development.
