Notes Standard CBM well construction involves drilling 15" OR 12.25" borehole to approximately 2300 foot depth and cementing 9 -5/8" casing, then drilling 8 -3/4" borehole into the
projected longwall fracture zone and casing the fracture zone with 6 -5/8" slotted casing for methane drainage.
Typical GVB well construction involves drilling 12.25" or 9 5/8" borehole to 20' above coal. 9 5/8" casing installed and cemented to 100' above coal. 100' of slotted 7 inch liner
to bottom of borehole extending up into the 9 5/8" casing 50'.
As noted, new road disturbance may provide access to several wells (existing roads used as noted) Some new road segments may be retained in conjunction with existing
ranch roads to provide ongoing access for the surface owner.
