Zusammenfassung:	A fluid slug consolidation is maintained in a fluid system for use in downhole applications. The fluid system has an interfacing fluid of a different character adjacent to the fluid slug. The method is carried out by admixing a particulate material with at least one of the fluid slug and adjacent interfacing fluid in an amount wherein discrete interfacing fluid margins are formed between the slug and the adjacent interfacing fluid under laminar flow conditions. The fluid system is introduced into a well bore of a well formed in a subterranean formation. In certain applications at least a portion of the particulate material is provided with adhesive properties to facilitate aggregation of the particulate material within the at least one of the fluid slug and adjacent interfacing fluid.
