Tracerco has developed a range of specialist tracer
technologies that allow measurement of interwell
flow of injected water, gas and enhanced oil
recovery chemicals. The technology is commonly
applied in new field developments that use
waterflooding or gas injection as part of their initial
recovery mechanism, as well as more mature
reservoirs where enhanced recovery programs are
used to extract incremental oil remaining within the
field. A Tracerco Interwell Tracer Study is typically
used alongside other reservoir surveillance tools
to refine or validate computer flow simulators
to optimise ongoing field design and ultimately
maximise hydrocarbon recovery.
Our technology provides measurement of water, gas
or steam flow from each injector to production wells
allowing the determination of:
- First injection water or gas breakthrough.
- Reservoir interlayer connectivity.
- Detection of fault block communication.
- The presence of high flow permeable channels.
- Measurement of flood wide reservoir preferential
Alongside dynamic flow information, the use of
specialist tracers allows additional information to be
gained concerning the effectiveness of enhanced oil
recovery applications such as:
- High permeable channel blocking.
- Release of immobile residual oil inflow paths
For cases of channel blocking, tracer can be
used to determine sweep extent and timing
prior to the blocking chemical addition and then
repeated afterwards. Data generated alongside the
measurement of incremental oil production can be
used to validate its effectiveness.
For mature reservoirs, tracers can be used to
benchmark residual oil saturation levels prior to a
tertiary recovery treatment. Subsequent measurement
of changes to residual oil within the formation allows
the effectiveness of a treatment to be determined.
