    摘要： Compositions containing a mixture of microcapsules and a bulk polymer, where the microcapsules have an oil field chemical contained within the microcapsules are described. The microcapsules can be present in a variety of configurations. The microcapsules contain a core or a micro-matrix containing the oil field chemicals. The core or micro-matrix can be surrounded by one or more polymeric shells, where each shell contains at least one polymer that affects the release of the oil field chemical from the composition. The compositions provide for the sustained release of an oil field chemical into fluid in an oil field reservoir over long periods of time. Methods of making the compositions and articles containing the compositions are described. Methods of tracing the movement of fluid in a hydrocarbon reservoir using the compositions, and methods of providing for the sustained release of oil field chemicals are also described.

    摘要： Use of a partitioning tracer for determining a property of a system is disclosed. The partitioning tracer comprises a sulfone compound having a log K0w value in the range -0.5 to 3. A method of determining a property of a system is also claimed and involves introducing a conservative tracer and a partitioning tracer in the system and monitoring production of the tracers over time to determine the property where the partitioning tracer is a sulphone according to the following formula. The system may be a reservoir and the property may be the residual oil saturation in the reservoir.
