Turning Filling Material into Proppant for Coalbed Methane in Poland—Crush Test Results

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...

Turning Source Code into a Design Material

Computer programming is a highly creative and explorative process. In spite of this, current programming tools provide significantly better support for well defined situations than for exploration. This makes programming unnecessarily difficult. This MSc thesis investigates how design professions use hands-on learning, materials and visual cognition to support creative problem solving. A cognit...

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...

Analysis of Slug Test Data From Hydraulically Fractured Coalbed Methane Wells

This paper presents new type curves for analyzingslug tests in hydraulically fractured coal seams. The type curves were viable producers, Therefore, these conventional slug test analysis developed using a finite-conductivity,vertical fracture model and techniques cannot be used to either assess the success of the fracturetreatmentor to evaluatethe px.t-fracture potentialof these are presented i...
