摘要
Oil field chemical delivery fluids containing a mixture of a base fluid and microcapsules having an oil field chemical contained within the microcapsule are described. Chemical groups in the outer surface of the microcapsules interact with the base fluid and promote the dispersibility of the microcapsules in the base fluid. Chemical groups in the outer surface of the microcapsules interact with the targeted areas of a hydrocarbon reservoir and promote the substantivity of the microcapsules to the targeted areas of the reservoir. The oil field chemical delivery fluids provide for the placement of microcapsules in a desired location within the well and/or reservoirs using properties such as the density of the microcapsules. Methods of making oil field chemical delivery fluids, systems containing oil field chemical delivery fluids, methods of fracturing rock in a reservoir and tracing the movement of fluid in a hydrocarbon reservoir using these fluids are described.
