ABSTRACT:
A method of treatment of subterranean formations in which leakoff through natural fractures is controlled through the use of fibers. The method involves pumping a mixture of a formation treatment fluid and a fiber into the formation for matrix stimulation, fracture stimulation, diversion, and/or water control. In carbonate formations, the formation treatment fluid is preferably an in situ gelled acid. The method optionally also involves pumping the same or a different formation treatment fluid without fiber.
