THE ANSWER FOR COALBED METHANE WELL COMPLETION IS
HERE!
Centura's patented process
uses ultra high pressure water jet cutting technology capable of piercing
the casing and cement in seconds. This process eliminates conventional
perforating and acidization, both of which create problems for optimum
gas production.
Multiple laterals eight to ten feet in length and
ten inches or more in diameter are bored into the formation resembling
the spokes of a wheel from the vertical well-bore.
In cased wells with multiple pay zones, the process
is repeated at precise predetermined depths resulting in numerous slots
with a significant area of exposure and drainage in the coal seam. In
open hole completions, the area of influence of the jet completed well
is far greater than achieved by the under-reaming process presently
used for completion.
The jetted completion results in a sixteen to twenty-foot
diameter area of exposure to the formation at multiple depths, eliminating
the cost and potential damage of a frac job in most wells, and better
directs the frac if implemented.
The focused cutting stream, capable of cutting through
16 inches of steel uses approximately 4 gallons of water per minute
pressurized to 55,000 psi, exits the cutting head at mach 3 enabling
the tool to "horizontally drill" and never physically leave
the vertical well bore.
The jetting process typically requires only two
days on the site, and the costs are far less than conventional completion
techniques.
