Coal Seam Gas Completions and Production: Principles & Best Practices
Looking for productive coals:
Permeability is key
Strategy for low perm coals
Video Tutorials
Drilling the wells:
Horizontal wellbore stability - during drilling
Wellbore stability during production - hole collapse and fines
Liners
Examples of commercial production:
Highlights of industry survey
Benchmark to predict success in new CBM play
Recent successful CBM plays
Testing the coals:
Pre-completion testing - IFOT versus DFIT versus DST
Pilot testing
Choosing a completion:
Horizontals and multilaterals
Under-ream, cavity, hydraulic fracture
How to choose - decision trees
Diagnosing a completion:
Methods - tracers, microseismic, tiltmeter, frac pressure, well testing
Field cases
Benchmarking completion via production:
Simple rule-of-thumb to evaluate completion
Field examples
Frontiers:
Fracturing horizontal wells
Producing coals with perms < 1 md
Perm changes during production
