To characterize the path of an injector's fluid flow, chemical tracers can be used to determine the flow direction and sweep efficiency from injector to producer. This data can be used to identify the location of any potential thief zones (high perm streaks, natural fractures, faults etc.) and empower the operator to realign injection patterns and execute conformance improvement programs.

Tracer testing has become a popular tool to reduce the uncertainty of reservoir models by determining the degree of connectivity between well pairs. By combining tracer data with field production history, tracers can provide a baseline for volumetric sweep efficiency and is a critical exercise prior to beginning an EOR project. Flow quantification is carried out using mean residence time distribution analysis (RTDA) and can be used to estimate many valuable reservoir parameters.

ResMetrics offers a wide range of chemical tracers suitable for tracing most IOR/EOR project types. From basic waterflooding to advanced EOR injection, our chemical tracers have been screened in the laboratory and in the field for use during flooding operations. Produced fluid compatibility tests can be carried out beforehand to ensure compatibility with injection & formation fluids.

ResMetrics provides all high-pressure injection equipment required to pump the chemical tracers downhole.

ResMetrics offers unparalleled expertise in tracer test design, injection, and analysis for IOR/EOR projects. The design phase of a tracer program is critical to ensure reliable detection of the injected tracer at offset producers in the well pattern. The timing of tracer injection is of equal importance since tracer arrival will depend on the state of reservoir voidage or fill-up. Our engineering teams will provide a detailed technical proposal which will walk through all of the steps of the tracer test.
