The Permeability Factor in Coalbed Methane Well Completions and Production

SPE Western Regional Meeting, 2010
Abstract After 30 years of CBM production in the USA, and internationally more recently, general principles and decision trees have emerged to guide an operator in choosing a well completion based on permeability. If enough permeability measurements are made, well completions can be prioritized, and hybrid well completions evaluated. The

Application of Well Temperature Logging in Coalbed Methane Well Fracture Effectiveness Evaluation

Applied Mechanics and Materials, 2014
Mature oil well temperature logging technique was applied to coalbed methane wells in order to monitor the fracture height and guide the fracturing and drainage. The results show that, after fracture treatment, fracture height was bigger than that of perforated interval, and mainly extended upward.

Effect of Coal Dust on Coalbed Methane Wells Productivity

Advanced Materials Research, 2013
CBM has the largest reserve except for conventional natural gas and is the cleanest energy. However, neither coal seam permeability nor CBM vertical well productivity has been determined when the immigration of coal dust are considered, which restricts the economic CBM exploitation.

Magnetic Orientation Method for Coalbed Methane Connected Wells

Geological Journal
ABSTRACT In the context of connected wells, a rotating array magnetic dipole model is utilised to study the spatial propagation characteristics of the active alternating magnetic field. A low‐frequency alternating magnetic field guiding and positioning algorithm for connected wells is proposed, and a characteristic magnetic field ...
