Automatic Trend Tracking Model for Coalbed Methane Production Forecast

Well Evaluation for Coalbed Methane

Coalbed Methane Canister Desorption Techniques

The British Columbia Geological Survey Branch and the Geological Survey of Canada have initiated ajoint project to assess the coalbed-methane potential of coal deposits in British Columbia. This project entails participation with private industry to obtain fresh coal samples for desorption from exploration projects throughout the province. Samples are collected from the drill site and undergo a...

Permeability Variation Models for Unsaturated Coalbed Methane Reservoirs

A large number of models have been established to describe permeability variation with the depletion of reservoir pressure to date. However, no attempt has been made to draw enough attention to the difference in the effect of various factors on permeability variation in different production stages of unsaturated CoalBed Methane (CBM) reservoirs. This paper summarizes the existing and common per...

Automatic Text Categorization Using Trend-Tracking Technique

In this paper, we propose a novel text categorization method using trendtracking technique. The method classies texts by tracking the transition of information in them. Therefore, it can deal especially well with texts whose content transits gradually with the passage of time, such as Internet news articles, newspaper articles, or web pages which are often updated. Experimental results show tha...

Production Forecasting of Coalbed Methane Wells Based on Type-2 Fuzzy Logic System

Coal bed methane (CBM) reservoir production is controlled by a large set of parameters: geology, tectonics, reservoir, completion and operation. Its simulation process is complicated, relative information is difficult to be obtained, so it is necessary to analyze accurately coal bed gas potential production capacity by adopting other mathematics methods in case of incomplete information.
