The present invention involves a pack-off system for use in packing off an area of interest within a wellbore. The pack-off system comprises at least two packing elements disposed on a tubular body. The packing elements of the present invention comprise overlapping leaves which are pivotally mounted on the tubular body. The present invention further involves a method for using the pack-off system, wherein the packing elements are placed adjacent to an area of interest within a wellbore. The overlapping leaves of the packing elements are extended radially to effectively obstruct fluid flow in the annular space between the outermost portions of the packing elements and the wellbore. The bulk of the fluid introduced into the wellbore is trapped between the packing elements and is thereby forced into the area of interest.

A stay-in-place method of manufacturing a composite form that is used to provide a strong and durable concrete structure. The form includes a composite shell having an inner wall surface defining an enclosure into which concrete may be poured and allowed to harden. The composite shell may be made of one or several layers of fabric having a resin matrix impregnated therein. The concrete hardens to form a concrete core within the enclosure and a liner is affixed to the inner wall surface of the composite shell to protect the composite shell from alkalinity in the concrete core. The liner includes at least one sheet of a water-impermeable material to protect the concrete core from water and other corrosive elements. The fabric layers are selected such that the fibers elongate as the concrete is poured into the enclosure due to a weight of the concrete and partially shrink back to compensate for shrinkage of the concrete as the concrete dries to form the concrete core. Such stay-in-place composite form can be used in prefabricated form to strengthen new constructions.

The invention provides durable nonwoven fabrics comprising staple fibers. Methods of preparing durable nonwoven fabrics based on staple fibers are also provided.
