A well servicing rig for communicating with a fluid source and an efflue nt reservoir (such as a flow back tank) has an apparatus for holding and dispensing coiled tubing. A manifold assembly is advantageously located on the rig for routing the pressurized fluid (such as nitrogen gas mixed with proppant) fro m the fluid source between the coiled tubing apparatus, the well and the effluent reservoir. The manifold assembly controls the flow of the fluid to perform fracturing operations, for reverse fluid circulation, for a common coiled tubing operation, for pressure testing, and the like. The assembly includes remotel y controlled valves and pressure transducers for controlling the fluid flow, a nd chokes for diffusing fluid energy prior to entering the effluent reservoir. The rig, fluid source, effluent reservoir and a fluid pumper provide a novel method o f servicing an underground formation (such as a coal bed) for natural gas.</SD OAB>
