How do you identify bypassed zones and determine the remaining recoverable fluids?
Field reservoir management is needed to recognize the number of intervals involved, the age of the wells and the likelihood of oil being bypassed. Carbon/Oxygen (C/O) logging can be used to identify zones with oil saturations and where additional recovery is feasible.
The RMT Elite™ reservoir monitor tool is a unique through tubing C/O system, offering two to three times higher measurement resolution than other through tubing C/O logging systems. Its high-density Bismuth germanium oxide detectors allow the RMT Elite tool to achieve resolutions previously available only with larger diameter C/O systems. As a result, it can be used to run continuous passes in low porosity formations while other systems can only be run in a stationary mode. It can also be conveyed into a well with tubing completions, unlike larger C/O systems that can only log through casing.
Formation saturation analysis using the RMT Elite tool and porosity data can be provided via Halliburton's cased-hole formation evaluation interpretation in the following software models:
- CarbOxSat™ model oil saturation analysis using C/O measurements
- SigmaSat™ model water saturation analysis using capture cross section measurements (Σ)
- TripleSat™ model three-phase oil, gas, and water saturations using both C/O and Σ measurements
- Chi Modeling® computation service
From open hole to cased hole, coring or laboratory analyses, Halliburton offers multiple solutions that contribute to improving reservoir recovery.
