Multiseam coal stimulation by coiled-tubing fracturing
In Virginia, coalbed methane (CBM) can be produced from as many as 25 seams in the same well. Fracture stimulations have evolved from single-stage, limited-entry designs to multiple-stage treatments with increased gas production as more stages are added. A five-well project in Buchanan County, Virginia was chosen for multiple-stage coiled-tubing fracturing (CTF). Treatments consisted of 10 to 19 stages.
