    摘要： An improved method for transport of particulate matter in a wellbore fluid, and particularly the transport of particulate matter in subterranean wells, such as hydrocarbon wells, is disclosed, the method being characterized by utilization of specified fibers to aid in transport of the particulate matter. Additional embodiments include the removal of particulate matter (particles) and particle deposits, such as from drill cuttings, during the drilling of wells, and the removal of particulate matter deposits in cleanout operations.

    摘要： A method is given for treating a subterranean formation penetrated by a wellbore with a viscosified fluid. The fluid contains a solid hydrolysable polyacid that upon dissolution and hydrolysis releases an acid that is a breaker for the viscosifying system. Suitable solid hydrolysable polyacids include polylactic acid and polyglycolic acid. The fluid also contains a pH control agent, present in an amount sufficient to neutralize any acid present in the solid hydrolysable polyacid before the injection and to neutralize any acid generated by the solid hydrolysable polyacid during the injection, so that the acid breaker is not available to break the fluid during the injection. In one embodiment the viscosifier is a viscoelastic surfactant fluid system and the solid hydrolysable polyacid is of a size selected to be a fluid loss additive, for example in fracturing or gravel packing. In another embodiment, the solid hydrolysable polyacid is used in particles sufficiently small that they enter the pores of the formation. In either case, the viscosifier is broken after the solid releases more acid than can be neutralized by the pH control agent.

    摘要： Methods and apparatus for forming a fluid for use within in a subterranean formation comprising combining a partitioning agent, crosslinkable polymer, and crosslinker into a fluid, wherein more than 50 percent of the crosslinkable polymer crosslinks and less than 10 percent of the partitioning agent crosslinks, and introducing the fluid into the subterranean formation. Methods and apparatus of forming a fluid for use within in a subterranean formation comprising combining a partitioning agent, crosslinkable polymer, and crosslinker into a fluid, wherein a critical polymer concentration for crosslinking the crosslinkable polymer is lower than if the partitioning agent were not in the fluid, and introducing the fluid into the subterranean formation.
