Methods for servicing subterranean wells |
abstract |
Methods for controlling fluid flow through one or more pathways in one or more carbonate-rock formations penetrated by a borehole in a subterranean well, comprise injecting into or adjacent to the formation a treatment fluid comprising at least one viscoelastic surfactant; fibers, or a mixture of fibers and particles; and at least one acid. The initial fluid viscosity is sufficient to transport the fibers and particles; however, upon reacting with the carbonate rock, the fluid viscosity falls. The lower fluid viscosity promotes efficient fiber bridging across the pathways, thereby providing diversion. |
