Well Evaluation for Coalbed Methane

Numerical Simulation of Coalbed Methane Seepage in Pinnate Horizontal Well Based on Multi-Flow Coupling Model

Abstract: The motive of the study is to establish a seepage flow model of pinnate horizontal well in infinite reservoir according to the characteristics of 3D distribution of CBM pinnate horizontal well. Taking flow pressure drop along the main and branch boreholes into consideration, the fluid flow formulas of CBM pinnate horizontal well are proposed. The corresponding calculation program has ...

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...

Metagenome-Assembled Genome Sequence of Pseudomonas stutzeri Strain CO183 Isolated from a Coalbed Methane Well

A near-complete Pseudomonas stutzeri draft genome was extracted from a coalbed metagenome. The draft genome described herein provides insight into the functional pathways encoded by this bacterium and its potential role in coalbed methane environments.

Research of Coalbed Methane Development Well-Type Optimization Method Based on Unit Technical Cost

Coalbed Methane (CBM) is a high-quality unconventional energy resource. The successful development and utilization of a CBM resource needs to consider technical feasibility and economic viability. These factors are also necessary for the improvement of production safety in coal mines, reducing carbon emission, and optimizing energy structure. Because of its unique resource characteristics, surf...
